* ''VideoGame/AzureStrikerGunvolt2'': Gibril's Septimal power, "Metallon", lets her manipulate metals. She usually uses blood as her source of iron, whether taken from draining people's blood or (when she's desperate enough) her own. When she TurnsRed, she unleashes ''massive'' amounts of blood to use the iron against you... [[SurprisinglyRealisticOutcome and keels over from the blood loss shortly thereafter]].

* In ''TabletopGame/TheGatesOfHell'', the archdevil Sammael carries a rapier made out of iron drawn from the blood of thousands of humanoid creatures. It suppresses the healing of anyone struck by it. Marks of the Dark Ministry are Blood Iron as well.

* One ''Roleplay/EmbersInTheDusk'' sidestory has Ophelia collecting her own blood for over a year in order to make an iron amulet.

* ''Manga/JoJosBizarreAdventureGoldenWind'': Risotto's Stand, Metallica, is capable of [[ExtraOreDinary manipulating iron]], including the iron present in the blood of a person. Being a [[TheMafia Mafia]] assassin, his methods aren't pleasant to watch; those unfortunate enough to be within Metallica's range will find themselves coughing out ''razor blades'' from their throats, and will discover all sorts of sharp, nasty objects protruding from their face and neck. Assuming blood loss doesn't kill them first, anyone unlucky enough to be subject to Metallica's power will eventually suffer a horrifyingly fast version of iron deficiency anemia and then asphyxiate, as the Stand robs enough iron from the victim's blood to prevent it from transporting oxygen, turning the blood ''yellow'' as it literally sucks every last atom it can out of the victim's blood, presumably destroying the hemoglobin and red blood cells and leaving only the blood plasma and other cells behind. Victims who somehow survive for long enough against this onslaught can also look forward to being bombarded by iron objects made from the surrounding environment, as Metallica is perfectly capable of manipulating iron in other natural sources as well, such as in rocks and the ground, and in other non-human organisms.

* ''Manga/{{Naruto}}'': Long after its introduction, [[NamedWeapon Zabuza's sword Kubikiribouchou]] is revealed to have the power to repair itself by drawing iron from the blood it spills.

Related is the idea of quenching a newly-forged blade in blood, possibly by stabbing it through a living body, which is said to give it a soul. This absolutely would not work in real life.

* [[ImpliedTrope Implied]] in ''Fanfic/TheNightUnfurls''. Kyril's Saw Cleaver is referred to as "blood-forged iron" by the narration in Chapter 5, remastered version.

* In ''Literature/MakingMoney'', there's a rumor that the blade of Lord Vetinari's (alleged) SwordCane is made from the blood of a thousand men. Given that Vetinari is the pragmatic sort, it's unlikely to be true (so the one that ends up being made is a regular sword, but treated with chemicals and a bras brush to "create a sword that looked like it would leap for your throat of its own accord".) It's actually not even clear whether it actually contains a sword, or if it's just one of the many rumors surrounding him. It seems a reasonable enough conjecture that, in any case, it would be deadly enough in his hands [[CaneFu as a stick.]]
* In the Literature/WhateleyUniverse, Bloodsteel, both due to the name and the description of something with a [[http://whateleyacademy.net/index.php/content_page/9-original-canon/312-call-the-thunder-part-5 hell of a lot of bloodsteel]], meaning "far too many people died in the process" of its creation, implies that blood is a component. It is not quite clear what it actually is though.
* In ''Literature/TheWheelOfTime'' the process of creating blades for the Myrddraal includes stabbing someone with it, though it's not explicit this is to quench the blade.

* ''Literature/TheLongEarth'': Chemical iron, ie. blood iron, is stated to be the only form of iron that can be taken across the Long Earth. Why is unknown, but it rather fits with the idea of normal iron disrupting the "magic" of stepping inherent to most other denizens of the Long Earth.

* In the {{Website/Reddit}} creepypasta ''[[https://ar-ar.facebook.com/permalink.php?story_fbid=1213276002140176&id=179682905499496 Pig Iron]]'', an eccentric master blacksmith is inspired by the idea of making "pig iron" (crude iron made from smelting iron ore in a blast furnace) [[MadeFromRealGirlScouts from actual pigs]]. He makes a knife out of iron extracted from the blood of 100 pigs, and later a sword from the blood of 300 pigs, which turns out to be an AbsurdlySharpBlade that can slice through solid steel. He gets approached by a woman whose master (implied to be Satan himself) is requesting a sword made from the blood of humans instead.
