* ''Franchise/{{Batman}}'':

* The Corinthian, in his first appearance as a villain in ''ComicBook/TheSandman'', 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]].
* In ''ComicBook/NewKrypton'', both [[GeneralRipper General Zod]] and his [[UnholyMatrimony equally insane wife]], [[ColonelKilgore Ursa]], carried knives with Green Kryptonite blades for use against [[Franchise/{{Superman}} their]] [[ComicBook/{{Supergirl}} fellow]] [[ComicBook/{{Superboy}} Kryptonians]].

* [[SpellMyNameWithAnS Kuro(u)do(u)]] Akabane (aka 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]]...

* ''Manga/Reborn2004'': Belphegor. He's a knife-wielding psychopathic assassin in the Varia.

* ''Franchise/{{Batman}}''

:: : Like with Pamu:
--->'''Pamu:''' Wow! Some broad has been stalking me with a knife! She's so disturbed and adorable - I love her!\\
'''Ayano''': I think that Pamu might not be human... She laughs when she's stabbed... [[OrSoIHeard I hear.]]
:: : And Alpha:
--->'''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?\\

:: : And Quill:
--->'''Quill:''' Are Cat-Catchers allowed to use steak knives for their jobs? Because the one that's chasing me sure is.
:: : And regarding Elle:
--->'''Ayano:''' I heard people with narcolepsy sometimes slip and fall and stab themselves with knives 20 or 30 times. How awful!

* From ''Webcomic/StringTheory2009'', 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.]]

* ''Roleplay/DarwinsSoldiers'': Dr. Kerzach's WeaponOfChoice is his amorphous metal switchblade. He is quite proficient with its use as a weapon too.
* In ''Roleplay/TheGamersAlliance'', several assassins and thieves like using knives and daggers in their line of work. Sinlarine shamans have ceremonial daggers which are mostly for show but with which they can focus their innate powers to travel between the [[VoidBetweenTheWorlds Void]] and the Land of the Living by shifting from one plane of reality to another.
* Rhianna von Adolph from ''Roleplay/OpenBlue'' uses a [[NighInvulnerability diamond-coated]] combat knife, which she tends to playfully toss into the air and catch whenever she's talking to somebody. She can either chuck this at people with alarming accuracy, or cut them up seven times before they hit the ground.

* Min from ''VisualNovel/ButterflySoup'' is a fan of butterfly knives. When she is asked to hand over the rest of her knives, she takes her jacket off and several knives fall to the floor.

* In ''ComicBook/BatmanRIP'', the Joker makes frequent, [[NightmareFetishist borderline fetishistic]] use of twin switchblades to mutilate not just enemies and loose allies, but himself.

One 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 and relatively easy to hide -- a dastardly character can sneak one up their sleeves or put one in their boot, making the reveal of the blade's hiding place prime material for a TraitorShot. 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.

Overall, the vast majority of characters who wield a knife as their primary WeaponOfChoice fall somewhere on the "Chaotic" and/or "Evil" sides of the CharacterAlignment grid. The nicest you can expect is a ChaoticGood LovableRogue. Lawful Knife Nuts are practically unheard of.

->''"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 [[NeverSmileAtACrocodile 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."''

* ''Film/RepoTheGeneticOpera'': 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.

* ''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.]]
