14->''"A little bit o' pain never 'urt anybody... if you know what I mean. Also, I think knives are a good idea. Big, 'fuck-off' shiny ones. Ones that look like they could skin a crocodile. Knives are good, because they don't make any noise, and the less noise they make, the more likely we are to use 'em. Shit 'em right up. Makes it look like we're serious. Guns for show, knives for a pro."''
15-->-- '''Soap''', ''Film/LockStockAndTwoSmokingBarrels''

17Knives have a long history in media of being the weapon of choice for slasher villains, unhinged individuals, or anyone with a penchant for violence.
18
19One reason for this is that knives are ''scary'', as a single glimmer from its profile in AxCrazy hands has been known to provoke screeches of horror (that and the possibility that they're more painful than any gunshot will ever be). Another reason is that knives are very accessible -- if a once-sane person suffers from SanitySlippage, chances are they already have a kitchen full of sharp knives with which to get their killing spree started once their mental state reaches "murderous". Knives are also relatively easy to deal damage with, and a great way to release pent-up rage and hatred. Once a crazy knife-wielder gets close enough to enter a stabbing frenzy, it's almost impossible for their victim or those close by to stop them.

21Many knife nuts do the FiveFingerFillet to showcase their dexterity and general disregard for safety.
22
23A lot of them may double as {{blade enthusiast}}s.

34** Preference for katanas aside, Vicious throws a knife into Spike's shoulder in their final match. He also uses a combat knife to literally StabTheScorpion and thus gain Gren's trust. While he's perfectly capable of handling guns, his use of blades in his later years reflects his more openly AxCrazy behavior.
35* In ''Anime/DigimonGhostGame'', the CyberNinja [[{{mons}} Digimon]] SerialKiller [[KnightOfCerebus Sealsdramon]] exclusively attacks using its special attack "Death Behind", which is a thrown combat knife powerful enough to OneHitKill even other Champion-level Digimon.
36* ''Literature/{{Durarara}}'': [[spoiler:[[{{Yandere}} Haruna Niekawa]], while possessed by [[EvilWeapon Saika]], uses a knife to stab people with in order to [[TheVirus spread Saika's "children"]] before she snaps out of it.]]

Dr. Jackal) from ''Manga/GetBackers'' pulls off {{Diagonal Cut}}s in rapid succession with his (wait for it) scalpels, when he's not throwing them [[FlechetteStorm en masse]] [[CallingYourAttacks ("Deadly Rain!")]]. And you don't want to know where he [[BodyHorror stores them]]...
39* The NightmareFetishist narrator in ''Manga/{{Goth}}'' becomes one of these over the course of the series. He gets his first set of knives from a collection left behind in a home that a SerialKiller had abandoned and quickly becomes proficient with them, his own homicidal urges being a strong source of motivation.
40* Asakura Ryouko, the GirlWithPsychoWeapon in ''Literature/HaruhiSuzumiya''. Worse yet, it's a combat knife with nasty spikes on the backside. And Asakura can be scary. [[UncannyValleyGirl Very scary]].
41* ''Manga/MyHeroAcademia'':
42** Stain, the HeroKiller, is a crazed KnightTemplar on a mission to wipe out all heroes he deems "unworthy". Although his {{Katana|sAreJustBetter}} is his main weapon, he also carries several knives, including five daggers and some throwing knives, which he uses to draw his enemies' blood as his Quirk paralyzes whoever's blood he ingests.
43** Himiko Toga is an AxCrazy {{Yandere}} who carries multiple knives on her as her weapons of choice. She derives great pleasure from stabbing those she loves with them.
44* ''Literature/ReZero'': Elsa Grandhirte is an AxCrazy assassin who fights with [[KukrisAreKool kukri blades]].

52** Recurring rogue Victor Zsasz is a sadistic, AxCrazy SerialKiller who's murdered hundreds. His favorite weapon is a carving knife, which he uses to carve a KillTally onto his own body after each kill.
53** In ''[[ComicBook/BatmanGrantMorrison Batman RIP]]'', the Joker makes frequent, [[NightmareFetishist borderline fetishistic]] use of twin switchblades to mutilate not just enemies and loose allies, [[CombatSadomasochist but himself]].
54* The Corinthian, in his first appearance as a villain in ''ComicBook/TheSandman1989'', seems very fond of knives. This is both for creepy purposes (menacing a victim with one in his hand, [[MuggingTheMonster taking a felled mugger's switchblade]] and opening it in front of his face while commenting on how nice a knife it is...) and for [[EyeScream much more practical ones]].
55* In ''ComicBook/NewKrypton'', both [[GeneralRipper General Zod]] and his [[UnholyMatrimony equally insane wife]], [[ColonelKilgore Ursa]], carried knives with Green Kryptonite blades for use against [[ComicBook/{{Superman}} their]] [[ComicBook/{{Supergirl}} fellow]] [[ComicBook/{{Superboy}} Kryptonians]].
56* Van Grote, a Hessian TortureTechnician from ''ComicBook/{{Tomahawk}}'' #112 who fancies himself the finest knife thrower in Europe.

58
59[[folder:Fan Works]]
60* ''Fanfic/ACertainDrollHivemind'': Abe Eiko, it turns out, was a Dark Side assassin who liked using knives. She managed to get herself benched by flubbing a mission, but she's still very fond of her knives. She admits she's trained in guns, but prefers her knives because "the rush is so much better, you know?"
61-->She smiled at me. Her smile was lopsided - the right side of her mouth turned up more than the left side. I flinched when suddenly a knife appeared in each hand. They were thin blades considerably more narrow and pointed than a standard combat knife. They were also made of swirling black and white indicating that they were made via [[ThePowerOfCreation her esper power]].\
62She held them like she was familiar with their use. The Network was alarmed, but also pleased that we had predicted the threat posed by Abe Eiko correctly.
63* In ''Fanfic/{{Coveralls}}'', [[Series/TheXFiles Scully]] acts a lot more unhinged than normal and has a "knife office".
64* ''Fanfic/AMothToAFlame'', [[FaceHeelTurn Marcy]] was given a LaserBlade knife by Andrias and during her VillainousBreakdown stabs Sasha in the leg with it with a SlasherSmile.
65* In ''Fanfic/OldWest'', two of the antagonists, Ramirez Arvenga and Kepper, fight with knives. The former is fond of using his knife in collecting {{Creepy Souvenir}}s, while the latter is unhinged and carries with him every kind of knife imaginable. He's even known by the trope name.
66[[/folder]]
67
68[[folder:Films -- Live-Action]]

70* ''Film/TheDarkKnight'': The Joker carries a number of knives on him. He states that they're his preferred weapon because he can [[ColdBloodedTorture savor]] his victims' subtle changes in expression as they die. He even carries a [[NoodleImplements potato peeler]].
71* ''Film/DickTracyDetective'': Splitface hacks his victims to death with a surgeon's knife stolen from an undertaker.
72* ''Film/DieHardWithAVengeance'' has Katya, and to make clear she's very psycho, as the baddies invade the federal reserve, she repeatedly slashes a guard until Simon holds her back saying "I think he's dead, my dear."
73* ''Film/DunePartTwo'': This is one of Feyd-Rautha Harkonnen's defining character traits. In his EstablishingCharacterMoment, he gets presented a set of knives by a servant which he proceeds to test out by killing two of the handmaidens attending him, ends up LickingTheBlade of one of the knives, and berates and punishes the servant as he deems the knives are not sharp enough for his tastes. He is also shown to be a {{Sadist}} who takes great pleasure in torturing some of the Atreides captives before having them drugged to fight him in the arena as part of his coming of age celebrations.
74* ''Film/DustDevil'': It's the Dust Devil's weapon of choice when he cuts up his victims.
75* ''Film/TheElf'': The elf doll is seen with a knife in its hand for most of its scenes. When it attacks people, it sometimes uses it.
76* ''Franchise/{{Halloween}}'': While Michael Myers is known to murder his victims with anything he can find, or with his bare hands, his most iconic weapon is a pointy kitchen knife. He's also a complete sociopath who shows no emotions or empathy; all he lives for is murder, murder, and murder.
77* ''Film/TheHobbitTheDesolationOfSmaug'': When the Company is taken into custody by the Mirkwood elves and searched for weapons, Fili is shown to be carrying an improbable number of knives concealed on his person.
78* ''Film/TheLocals'': [[HillbillyHorrors homicidal farmer Bill]] favours the knife, and all of his kills are made with one.
79* In ''Film/Masquerade2021'', Rose stabs [[spoiler:Daniel]] repeatedly with a kitchen knife, and there are several lengthy shots of the leather-clad intruder holding the blood-smeared weapon just to emphasize how crazy this woman is. [[spoiler:Subverted with the reveal that Rose is doing this out of revenge for Daniel killing her parents.]]
80* ''Film/TheNewYorkRipper'' [[GuttedLikeAFish eviscerates]] his victims with a variety of knives.
81* ''Film/{{Nightbreed}}'': The serial killer [[PsychoPsychologist Dr. Decker]] prefers to use huge carving blades to kill his victims, often appearing with one in each hand. He's briefly seen in his apartment with an entire collection of knives and blades laid out in front of him on a conference-style table.
82* ''Film/{{Psycho}}'': In the scary category, the shower scene of Creator/AlfredHitchcock's masterpiece involves a screaming woman, a big knife, and [[PsychoStrings scary music]].
83* ''Film/RazorsTheReturnOfJackTheRipper'': Jack the Ripper uses a box set of knives, each of which has a special meaning to him. The knives are so much a part of him that they constitute an EvilWeapon and allow his spirit to return to Earth.
84* ''Film/RepoTheGeneticOpera'':
85** Luigi Largo. He's known to have sex with the stab wounds he's inflicted, among other delightful things. The Repo Man himself, though his "companion" technically makes him a Scalpel Nut.
86* ''Film/RipperLetterFromHell'': The killer wields a large butcher's knife.
87* ''Film/{{Scream}}'': Every killer that takes the mantle of Ghostface. Has almost always used a rather unique Buck 120 hunting knife, although how they appear usually changes quite a bit. An interesting fact about the Buck 120 is that it was seen on the film posters of ''[[Film/FridayThe13thTheFinalChapter Friday the 13th 4]]'', ''[[Film/FridayThe13thPartVIITheNewBlood 7]]'' and ''[[Film/FridayThe13thPartVIIIJasonTakesManhattan 8]]''. The knife's appearance on these iconic horror film posters may be why it was chosen as Ghostface's primary weapon.
88* ''Film/ShaPoLang'':
89** Jack, the psychotic Triad assassin played by Creator/WuJing, does most of his killings with his tanto knife.
90** Ah Zai, the evil [[NoBrows browless]] assassin from [[Film/ShaPoLangIIATimeForConsequences the sequel]], does knives as well. His weapons of choice are folding knives that he uses both for melee and for throwing. He ultimately faces down Chan Chi-Kit, who is played by Wu Jing, in a furious duel that is reminiscent of Jack's final battle with Ma Kwun from the first movie.
91* ''Film/SpecialFemaleForce'': TheDragon Lung is a deranged {{Sadist}} that favors using a wicked-looking serrated knife as his weapon. Right in his first scene in the ActionPrologue, he's seen practicing his skills by scattering a box of cockroaches all over the road he's sitting on, and then using his knife to skewer roaches. Later his HandStomp method on the heroine who's HangingByTheFingers is to gleefully drive his knife underneath [[{{Fingore}} her fingernails]], slowly tormenting her until the pain gives away, causing her to fall to her death.
92* ''Film/SuspectZero'': SerialKiller O'Ryan uses a long, curved dagger, both for killing his victims and his signature of removing their eyelids.
93* ''Film/{{Sockbaby}}'': Though initially he might seem to be a wacky ninny, Davis The Grey is still deadly with a switchblade. [[spoiler:He uses one to murder Burger in the car and steal Sock Baby while Ronny is distracted, and very nearly defeats Ronny with it.]]
94[[/folder]]
95
96[[folder:Literature]]
97* ''Literature/AngelsOfMusic'': Rollo is the knife-thrower in ''Le Théâtre du Grand-Guignol'' in "Guignol" who is dismissed for collaborating a little too willingly with the horrors. He returns in "Deluge" equipped with dozens of blades and looking to exact vengeance on the Angels by skinning them.
98* ''Literature/{{Discworld}}'':
99** Jonathan Teatime is a knife-wielding, [[PsychopathicManchild psychopathic]] [[PsychoForHire assassin]] in ''Literature/{{Hogfather}}''.
100** Carcer Dun is a knife-wielding, psychopathic SerialKiller who always has an extra one.

102* In the ''Literature/{{Fingerprints}}'' series, one villain says the memorable lines, "I wonder how many cuts it will take you to die? I bet thousands and thousands..."
103* The original novel version of ''Manga/{{Goth}}'' has several of these.
104** The café owner uses a case of knives to carry out his murders. After deducing the café owner's identity, Itsuki takes the knives for himself. [[spoiler:He later lends one knife to a little girl so that she can kill her abusive stepfather with it.]]
105** Mr. Shinohara uses a meat cleaver to cut off the hands of his victims.
106* Clove from ''Literature/TheHungerGames'' has many knives and is very skilled at throwing them. She is also quite sadistic, what with trying to torture Katniss to death and all.
107* Bèbelle from ''Literature/{{Malevil}}''. A CreepyCrossdresser [[DisguisedInDrag who pretends to be a woman]] to get close enough to cut throats.
108* ''[[Literature/InDeath New York to Dallas]]'' has Isaac [=McQueen=], a pedophile and murderer who "favors knives as weapons and as a means of intimidation".
109* Sonia Steiglitz, the beautiful and sadistic daughter of the ex-CIA chief/archaeologist villain of ''The Takers'', a modern TwoFistedTales homage by Jerry Ahern. She uses guns when necessary, but prefers a knife.
110* ''Literature/TheWheelOfTime'': The MergerOfSouls between Padan Fain and Mordeth makes them even more unhinged and malevolent than their component parts, and they wield a [[EvilWeapon cursed dagger]] from Mordeth's home city that they think of as a part of themselves. Whereas the dagger can reduce anyone else to a mess of putrefaction with [[DeadlyScratch a scratch]], Fain takes up LickingTheBlade.
111* ''Literature/TheWitchOfKnightcharm'': The witch Chosovi is introduced while sharpening knives, and when an annoying rookie keeps bothering her, Chosovi very quickly starts joking about stabbing her.
112* ''Literature/{{Worm}}'': While the mass murdering supervillain Jack Slash can use just about any blade as a conduit to project their cutting edge invisibly, he most often uses knives and razors.
113[[/folder]]
114
115[[folder:LiveActionTV]]
116* ''Series/Batwoman2019''. The balisong is the weapon of choice for mad supervillain Alice, who lampshades the advantage of being able to [[EvilIsHammy flip it around in a menacing fashion]] while explaining your EvilPlan.
117* ''{{Series/Dollhouse}}'' has Alpha, who really shows a love for slashing and cutting people during his more psychotic personality periods. He was already a psychopath before the mass upload and it just got worse.
118* ''Series/{{Forever|2014}}'':
119** In the pilot, when Henry's colleagues generally agree that he's highly creepy, the fact that he uses a large hunting knife as one of his main autopsy tools doubtless helps contribute to this image.
120** In both "Hitler On the Half-Shell" and "The Last Death of Henry Morgan" Henry has had bodies on his autopsy table of people Adam tortured to death as part of his quest to reacquire the ''pugio'' knife used in his first death, which was taken from him by the Nazis at Auschwitz. They were covered with long, straight wounds consistent with a knife, and Henry remarks, even before knowing who caused them, that they are the mark of a true sadist who was enjoying the torture. Adam has also used the knife on himself for the MundaneUtility of slitting his own throat simply to get out of a location unseen, thanks to his ResurrectionTeleportation.
121[[/folder]]
122
123[[folder:Music]]
124* Rob Cantor's "Music/{{Shia LaBeouf|Live}}" portrays Creator/ShiaLaBeouf as a hermit murderer who goes after his victims with a knife and [[ImAHumanitarian eats the bodies]].
125* Music/JimCroce:
126** Based on what Slim does to Big Jim in "You Don't Mess Around With Jim", he likely qualifies. To clarify, "And when the cuttin' was done the only part that wasn't bloody was the soles of the big man's feet. Yeah, he was cut in about a hundred places..."
127** The guy "Bad, Bad Leroy Brown" tangles with at the end:
128--->''Well, the two men took to fighting\
129And when they pulled them from the floor\
130Leroy looked like a jigsaw puzzle\
131With a couple of pieces gone''
132%%* While the Music/InsaneClownPosse are more associated with hatchets, Violent J has a solo track on ''The Amazing Jeckel Brothers'' titled "I Stab People". He follows up with a song called "Still Stabbin'" on the later album ''Bizaar''.
133[[/folder]]
134
135[[folder:Mythology and Religion]]
136* The Malingee of [[Myth/AboriginalAustralianMyths Yolngu lore]] is a creature that stalks people at night to stab them with a knife. You can tell it is coming thanks to its rattling knees, but it is usually too late.
137[[/folder]]
138
139[[folder:Podcasts]]
140* Fourvel from ''Podcast/ComedyBangBang'' is an orphan who stabs people to death over [[HairTriggerTemper perceived insults]], and often carries an array of knives with him.
141[[/folder]]
142
143[[folder:Radio]]
144* ''Series/DeadRingers'': Brian Perkins, gangland boss of BBC Radio 4, has a large knife he likes to use on those who incur his displeasure. He also occasionally uses it to help people in non-deadly ways, like opening lunchboxes. While calmly recounting his murder victims screaming like "stuck pigs".
145[[/folder]]
146
147[[folder:Tabletop Games]]
148* ''TabletopGame/Warhammer40000''
149** Konrad Curze (Basically Batman as a KnightTemplar SerialKiller) uses throwing knives rather than a gun. On the tabletop, they are the ''one of the few weapons in the game'' that can potentially circumvent Invulnerable saves altogether.
150** The Dark Eldar gladiator [[DarkActionGirl Lelith]] prefers dual-wielding knives in combat. In-game, the 8th Edition rules for Lelith's knives grant her extra attacks and are able to cut through all but the thickest armour.
151** In the ''Kill-Team'' spinoff game, the Chaos Legionaries team has the "Shrivetalon", whose primary weapon, Flensing Blades, are portrayed as paired knives on the Kill-Team upgrade sprue. On the battlefield, Shrivetalons have the ability to place a token representing a grisly, mutilated corpse to intimidate enemies, and can drain AP from nearby enemies by gruesomely killing people in melee. The general vibe is that of a SerialKiller who just so happens to be a SuperSoldier in PoweredArmour.
152[[/folder]]
153
154[[folder:Theatre]]
155* After she is rescued from the Wolf, Little Red Riding Hood in ''Theatre/IntoTheWoods'' is rarely if ever seen without her knife. It's implied that she becomes rather obsessed with hunting down wolves for her [[spoiler:fur cloak, with which she replaces her red cloak (taken by the Baker)]].
156* The ''Theatre/MrsHawking'' play series: Mrs. Hawking's preferred weapons are knives of all kinds, from a thin, sharp letter blade to throwing knives to a plain sturdy Bowie.
157* ''Theatre/SweeneyToddTheDemonBarberOfFleetStreet'': Sweeney Todd's weapon of choice is the straight razor. Between him and UsefulNotes/JackTheRipper, the razor soon developed a reputation as a murder weapon.
158* ''The Three Penny Opera'' by Music/KurtWeill and Music/BertoltBrecht is probably best remembered for its VillainProtagonist Macheath, or, as he's referred to by the song about him, ''Mack der Messer''. Or in English, ''Mack the Knife'', which is well known from the swinging version recorded by crooner Music/BobbyDarin. Although by the events of the musical Macheath is actually nuts coasting on his reputation, he clearly had a period where he earned that reputation and this trope applies.
159[[/folder]]
160
161[[folder:Theme Parks]]
162* [[Ride/UniversalStudios Universal's]] ''Theatre/HalloweenHorrorNights'': As you might expect from such a classic horror weapon, scareactors wielding these have shown up quite a bit over the years, including horror icons like Michael Myers and Norman Bates.
163[[/folder]]
164
165[[folder:Video Games]]
166* ''VideoGame/AssassinsCreedSyndicate'': Jack The Ripper is perhaps the most exaggerated version of the killer so far. Of course, he mostly wields a knife and a blade in general. However while the real killer mostly struck at night (or at least early morning hours), this version massacred in [[CreepyAwesome broad daylight]]. Also during the DLC, there were plenty of witnesses to Jack's bloody crimes, while the real Ripper was as elusive as a ghost.
167* ''VideoGame/TheBlackHeart'': Peketo has an infinite supply of knives that he uses in combat. Keep in mind that he murdered seven people for the sake of a color [[EnfantTerrible while he was still a preteen]].
168* In ''VideoGame/CultistSimulator'', knives are a common symbol of Edge, the aspect of struggle and strife. Particularly the case for one Edge-aspect cultist, Elridge, "an elegant man of [[AxCrazy inelegant habits]]". He becomes better at hiding the tools of his hobbies and [[BloodSplatteredWarrior other telltale signs thereof]] as he progresses within the cult, but at first:
169-->''He has almost learnt not to pick his teeth with his knife. He has not yet learnt to keep his knife in his boot.''
170* ''VideoGame/CrushCrush'': Ayano repeatedly tries to {{Murder the Hypotenuse}}s with knives and cleavers, although she does use other methods like TamperingWithFoodAndDrink.
171--> '''Ayano:''' ''[describing her new knife]'' Guaranteed not to slip, even when covered in... milk.
172:: Like with Pamu[=:=]
173-->'''Pamu:''' Wow! Some broad has been stalking me with a knife! She's so disturbed and adorable -- I love her!\
174'''Ayano:''' I think that Pamu might not be human... She laughs when she's stabbed... [[OrSoIHeard I hear.]]
175:: And Alpha[=:=]
176-->'''Alpha:''' My handlers told me that I received some poisoned chocolates.[[note]]This could be a possible reference to the game ''VisualNovel/LongLiveTheQueen''[[/note]] I wonder if by accident?\
177'''Alpha:''' I think someone tried to hack my servers today. And by "hack" I mean with a meat cleaver.
178:: And Quill[=:=]
179-->'''Quill:''' Are Cat-Catchers allowed to use steak knives for their jobs? Because the one that's chasing me sure is.
180:: And regarding Elle[=:=]
181-->'''Ayano:''' I heard people with narcolepsy sometimes slip and fall and stab themselves with knives 20 or 30 times. How awful!
182* Many of the Killers in ''VideoGame/DeadByDaylight'' wield knives. Some are famous and iconic {{Guest Fighter}}s from horror movies, such as [[Franchise/{{Halloween}} Michael Myers]] and [[Film/{{Scream}} the Ghost Face]], others are original characters such as the Legion and the Trickster. All are AxCrazy murderers whose goal is to kill every player on the Survivor team.
183* Although Lucas Kane in ''VideoGame/{{Fahrenheit}}'' never uses a knife outside the opening sequence, he is depicted holding a bloody blade on every box art to underline the psychosis surrounding him throughout the game.
184* ''VideoGame/FallenLondon'' has SerialKiller Jack-of-Smiles, an {{Expy}} of Jack The Ripper. [[spoiler:Actually, Jack-of-Smiles ''[[ArtifactOfDoom is]]'' his knives, which explains [[BodySurf his plentiful bodies]] to use. The knives are alive, have a mind of their own, and [[WeaponWieldsYou will take over yours]] if you hold one for too long.]]
185* ''VideoGame/FatalFury'': The PsychoForHire Ryuji Yamazaki habitually keeps a switchblade in his pocket. And he's not above shanking his foes with it while [[LaughingMad laughing his head off]].
186* In ''VideoGame/TheLegendOfZeldaSkywardSword'', Ghirahim is a vicious fighter who can summon an endless supply of daggers in his boss fights to use in conjunction with his sword.
187* ''VideoGame/LikeADragon'': One of Majima's signature weapons next to [[BatterUp a baseball bat]] is a tanto dagger he keeps on him at all times. Once that comes out, you learn right away why he's called the Mad Dog of Shimano.
188* ''VideoGame/MasterDetectiveArchivesRainCode'': Later in the game, we are introduced to [[spoiler:ProfessionalKiller Fink the Slaughter Artist, a local assassin-for-hire in Kanai Ward whose signature weapon is a knife with an F engraved on the hilt. The plot of Chapter 4 revolves around his supposed infiltration of Amaterasu's research lab. He ''did'' infiltrate it, and he promptly attacks Yakou with his knife (as part of Yakou's overarching murder plot), but the "psycho" part doesn't apply, as in this situation, he was actually attacking Yakou due to being ''hired'' to do so. In general terms, though, Fink is most definitely psycho about his use of knives as a weapon.]]
189* ''[[VideoGame/MysteryCaseFiles Mystery Case Files: Broken Hour]]'' introduces Meredith Huxley, a psychopathic woman who murders people with an ornate dagger.
190* ''VideoGame/{{OMORI}}'': Both Omori and Sunny use knives as their primary weapons. Add this to [[AxCrazy the way Omori looks when Manic]], and it's no surprise that much of the fandom sees him this way.
191* ''VideoGame/PathfinderKingmaker'': Nok-Nok is a HeroicComedicSociopath goblin who dual-wields kukri as his main weapons. While he believes the PlayerCharacter is his wise MentorArchetype [[HeroicWannabe who will turn him into a True Hero]] and thus never harms you or your companions, Nok-Nok will offer to "ssstab" practically everyone else you meet who cheeses you off.
192* One of the many signifiers that Pavia of ''VideoGame/Reverse1999'' is the Crew's TokenEvilTeammate is the maniacal ''glee'' Pavia has when using his knife to carve up his enemies.
193-->'''Pavia:''' Police's number? I'll carve it on your face!
194* ''VideoGame/TheSuperSpy'' has a mentally-unhinged terrorist assassin called "Geese" who fights with his knife, despite most other bosses using firearms. You first confront him in a conference room, where he's gleefully threatening a hostage with his knife, and the entire boss battle takes place in a badly-vandalized room sliced apart by Geese.
195* The original ''VideoGame/TimeCrisis'' has the BigBad, Sherudo Garo, who's an expert in throwing knives and in his introductory cutscene, happily taunting the kidnapped Rachel [=McPherson=] by holding his knife on her face, giggling all the way.
196* ''VideoGame/{{Undertale}}'': The final and most powerful weapon in the game is the Worn Dagger, but on the Genocide Route it becomes the vastly more powerful Real Knife (as opposed to the Toy Knife). Given that it presumably belonged to the First Fallen Human, and said human was [[spoiler: stated as sometimes making a "creepy face" and described as "not the greatest person," it's possible that they qualified as this.]] Given that by the end of the Genocide Route, both the player character and [[spoiler: the First Fallen]] have gone utterly insane, they probably both qualify as this even if they didn't before. Obviously, it's made a lot less ambiguous in most fan works.
197* Madotsuki from ''VideoGame/YumeNikki'' is frequently depicted as one because of a widespread PlayerTic which involves killing everyone, with the knife being the only weapon available.

201* In ''VisualNovel/DanganronpaTriggerHappyHavoc'', TheDragon [[spoiler:Mukuro Ikusaba]] is shown to be one of these. [[spoiler:Despite being the "[[TheAce Ultimate]] [[WorldsBestWarrior Soldier]]" whose official art has her with rifles and rocket launchers, in her various appearances throughout the franchise she's only ever shown using a combat knife to kill people. In fact, her skill with the blade was so great that she managed to fight MasterSwordsman Peko Pekoyama to a draw in ''Anime/Danganronpa3TheEndOfHopesPeakHighSchool'' despite a severe range disadvantage. She's also an amoral BrainwashedAndCrazy nutcase who shares a MasochismTango [[VillainousIncest with her own sister]].]]
202* ''VisualNovel/DokiDokiLiteratureClub'': [[spoiler:Yuri is one. If you go down the Yuri route in Act 1, it's revealed that she has a large collection of knives at home, and the one she brings over to the MC's home is [[AbsurdlySharpBlade so sharp that gently touching its tip causes bleeding]]. Yuri even says it "[[FridgeHorror cuts through skin like paper]]". Her SelfHarm tendencies are hinted at, as well, creating a real UncannyValleyGirl feeling about her. This is brought to full light in Act 2, where Yuri basically goes full-on {{Yandere}}, courtesy of Monika's MindRape combined with HostileShowTakeover, which worsens her obsessive traits and self-harm tendencies. You end up with some indiscretion shots of Yuri cutting herself (both of which are hijacked by Monika; one is rewound and the other has her physically manifest over the entire GUI), as well as the climactic ending of Act 2, where Yuri stabs herself to death, either as a show of [[DrivenToSuicide pure despair at the player refusing her confession]], or a show of [[EroticAsphyxiation pure ecstasy at the player accepting it]]. [[ButThouMust Either way, she dies.]]]]
203* The mysterious killer in the ''VisualNovel/{{Yarudora}}'' game ''VisualNovel/DoubleCast'' primarily uses a knife, giving much tension in the scenes where he assaults the protagonist and/or his friends.
204* ''VisualNovel/TheFruitOfGrisaia'': Yumiko always carries a box cutter with herself, usually only to scare off her classmates when they get on her nerves, but she actually tries to attack protagonist Yuuji with it after he makes a particularly bad first impression on her.
205* [[InUniverseNickname Guilio The Knife/Knifer]] from ''VisualNovel/LuckyDog1'' is extremely skilled with a knife, citing that it's his favourite weapon - Ivan comments that he's practically useless without one. It becomes very useful when he needs to do knife tricks so the team can pretend to be performers after escaping prison.
206* When sweet little [[spoiler:Kotonoha Katsura]] from ''VisualNovel/SchoolDays'' snaps after all the BreakTheCutie and [[{{Yandere}} her own emotional instability]], she grabs a cleaver and shows how well she can use it. Seeing the kid [[spoiler:[[SlashedThroat slash Sekai's throat]] open with it in one of the bad endings is... horrifying]]. In TheAnimeOfTheGame, it's even worse. [[spoiler:Sekai fatally snaps on Makoto by stabbing him repeatedly in the chest with a kitchen knife, and then Kotonoha stabs ''and cuts Sekai's stomach open'' afterwards with another ''huge'' knife... after revealing that she beheaded Makoto's corpse. [[AlasPoorYorick And then she carries the head with her.]]]]
207* ''VisualNovel/PrincessEvangile'': During Masaya's and Rise's backstory, they were both targeted by one such psycho, who stabbed Masaya in the back, resulting in his signature scars that he still has in the present. In the former's case, this psycho continues to haunt his nightmares on occasion. In Rise's route, [[TheReveal it turns out that the identity of this knife-wielder is]] [[spoiler:[[EvilMatriarch Kaori Rousenin]], Rise's own mother, who's suffering from severe mental stress and breakdown due to being unable to cope with life outside Vincennes.]]
208* Souji in ''VisualNovel/{{Suika}}'' always carries a silver knife in his pocket, but isn't actually a murderer or anything. But he does consider using it at several points and appears to have a fairly violent side that he suppresses. [[spoiler:It's finally justifiably used near the end, but he doesn't kill anyone.]]
209[[/folder]]

211[[folder:Web Animation]]
212* ''WebAnimation/HappyTreeFriends'': Flippy's murderous SplitPersonality Fliqpy can and will kill people with [[ImprovisedWeapon just about anything he can get his hands on]], but he also has a bowie knife he uses when it suits him.
213* ''WebAnimation/OnTheEdge'':
214** The episode ''[[https://www.youtube.com/watch?v=5r62XuBocrU Scorching Soy Sauce Method]]'' features one who killed the client's twin daughters. However, it turns out he was being used by a gang boss who claimed to have made a DealWithTheDevil.
215** In the episode ''[[https://youtu.be/y8srrB0eSEU Kurebayashi meets Satake]]'', Hirofumi gets attacked by a musclebound, underwear-clad man brandishing a knife. Things get more unfortunate when a second knife-wielding killer shows up.
216* ''WebAnimation/SpookyMonth'':
217** The [[PerversePuppet possessed Happy Fella doll]] in "Deadly Smiles" uses a kitchen knife, and at one point a switchblade, to attack people and satisfy his "[[{{Bloodlust}} needs]]".
218** Bob Velseb is a [[ImAHumanitarian cannibal]] SerialKiller with a whole host of knives and knife sharpeners hidden in a toolbelt under his sweater. His main weapon is a fillet knife, and he sharpens it when near his prey to intimidate them.
219** A movie Jaune watches in "Tender Treats" sees a woman accosted by a crazed killer wielding a boxcutter.
220* [[NamesToRunAwayFromReallyFast Mr. Stabby]] from ''WebAnimation/WeeblAndBob''. True to his [[MeaningfulName name]], he has a penchant for stabbing people (and drowning puppies). Oh, and his theme song has [[SoundtrackDissonance such a serene-sounding tune]].
221[[/folder]]
222
223[[folder:Webcomics]]
224* ''Webcomic/EightBitTheater'': The violently unstable, Hadoken-happy Black Mage keeps a dagger around in case he runs out of spells... or feels like using it on one of his "teammates".
225* ''Webcomic/BasicInstructions'': The Knifeketeer is an AntiHero version. He ''is'' [[ThePiratesWhoDontDoAnything about the only superhero to actually fight crime]], and ''does'' have a non-lethal knife that's a boxing glove on a very short stick, but is generally treated like a dangerous lunatic by allies and enemies alike. His sidekick, Stabby, is even worse; it's heavily implied that the crudely drawn S on his costume is a CreepySouvenir from [[SelfMadeOrphan murdering both of his parents]].
226-->'''The Judger:''' Knifeketeer, I know you've always wanted to stab Omnipresent Man. What do you say in your defense?\
227'''The Knifeketeer:''' I've always wanted to stab everyone. I just love to stab.\
228'''The Judger:''' Do you even know what the word "defense" means?\
229'''The Knifeketeer:''' [[IsItSomethingYouEat It's a kind of stabbing, right?]]
230* ''Webcomic/GirlGenius'': [=DuPree=] is ecstatic about getting to kill and torture and her implements of choice for both are the many little knives she keeps on her person at all times.
231* ''Webcomic/TheGuyUpstairs'': Adam’s preferred weapon of choice is a knife, which he uses to kill the woman in episode 3 via slashed throat and repeated stabbings.
232* ''{{Webcomic/Homestuck}}'': AxCrazy Jack Noir absolutely loves his knives, and has a habit of stabbing people with said knives. If he ever gets a chance to stab something, expect him to do it, even as a ''greeting''.
233* ''Webcomic/{{Lone}}'': Mostly PlayedForLaughs with [[MamaBear Lone's mother]] in a flashback. If somebody is ''actually'' threatening her daughter, she doesn't need a knife to make them stop.
234* ''Webcomic/TheOrderOfTheStick'': HeroicComedicSociopath Belkar Bitterleaf dual-wields daggers. While capable of holding the SanityBall on occasion (though he's probably the second-least likely to do so after Elan), Belkar is extremely violent and mostly kept in line by the rest of the gang threatening him with retributive violence if he steps out of line.
235* From ''Webcomic/{{String Theory|2009}}'', we have Professor Phineas Armastus, the resident [[SerialKiller psychopathic murderer]] of [[HellHolePrison Nevada State Penientiary]], who can clear a room of guards armed with automatic rifles in a matter of seconds with nothing but a pair of prison shanks. [[ArsonMurderandJaywalking And then take their gummy bears.]]

238[[folder:Web Videos]]
239* Part of Ryan Haywood's TokenEvilTeammate shtick in ''Creator/AchievementHunter'' videos is that he ''loves'' knives and his first objective in games is to murder. He also keeps a cup filled with them at his desk.
240-->'''Ryan:''' Why do I need a cup full of 37 knives? I don't, ''but I like it!''
241* Evan of ''WebVideo/EverymanHYBRID'' is an absolute fiend for knives, switchblades, cleavers, daggers, and knife gloves a la [[Franchise/ANightmareOnElmStreet Freddy Krueger]]. He's rarely seen without some kind of cutlery in his hand, which is getting increasingly worrisome, as he seems to be on a [[SanitySlippage greased slide to]] [[AxCrazy Ax Craziness]]. Oh, and [[spoiler:he's occasionally possessed by a disembodied homicidal maniac]].
242-->EMERGENCY. MACHETE.
243* ''WebVideo/RatsSMP'': [[{{Hypocrite}} In spite of being designated as the Safety Rat]], Jimmy is decidedly one of the more… ''unhinged'' rats, shall we say, and has been constantly running around with a knife since Day 1 and threatening humans every other day, [[spoiler:and is the only rat ''with a non-rat body count'']]. He is also the only rat who [[spoiler:endorses Scott's RevengeBeforeReason plan against the cats on Day 47 when he first hears of it, though his opinion immediately shifts to opposition when it's clear it's not working as intended.]]

247* Roberto, a mentally unstable robot from ''WesternAnimation/{{Futurama}}'', has an obsession with stabbing things with his trusty "Stabbing Knife".
