"Phenom is on his feet again, a little wobbly but still game. He's got his hands up, blades extended. Either of those things might take my head off like a dandelion."
It's common knowledge that blades are cool
. But they can also be a hassle to carry around everywhere. The scabbard might be uncomfortable, and the sword won't simply stick to your back
. On top of that, once you finally decide to unsheathe your weapon, you are no longer able to hold anything else in one or both of your hands (or make rude gestures
to your opponent). This problem is intensified if the weapon user intends to dual-wield
The solution: attach the blade to your arm, leaving your hands free to do whatever else you may be inclined to do with them. These blades are often long, vaguely triangular, and taper to a point. Variants include:
: Attaching the blades to your elbow, wrist, or even the back of your hand.
: Embedding the blades inside your arms, from where they can be deployed and retracted by thought alone
(usually employed by robots, cyborgs
, and other non-regular human
: Replacing one or both
of your hands
or even your arms
with large swords.
The last type is Awesome but Impractical
, as the blades prevent their wielders from performing mundane tasks when not in combat. They are also especially prone to Fake Arm Disarms
, as they can be destroyed without gravely injuring the characters. While these drawbacks mitigate many of the practical benefits of having swords attached to your body as opposed to carried, few will have the guts to question your coolness
are a specific variant. May overlap with Swiss Army Appendage
. Can be considered a subtrope of Cool Sword
. Compare its counterpart Arm Cannon
, as well as Power Fist
. Not to be confused with Shapeshifter Weapons
, which are not limited to simply being blades. See also Hook Hand
. Compare Combat Haircomb
The examples below are divided into three categories: one, where a blade attached to the arm is a weapon of choice, but not a permanent body part; two, where the blade is permanently attached to the arm and may or may not be concealable; and three, where the entire arm is
open/close all folders
Type I (removable arm blade):
Anime and Manga
- Angel from Angel Beats! has five of these as her first Guard Skill.
- A signature weapon of the titular character in Battle Angel Alita. The "Elbogen Blatt" style of "Panzerkunst" uses backwards-pointing blades attached to the "künstlers" forearms.

- In the anime, the Robot Girl Chachamaru from Mahou Sensei Negima! gets a long, thin, retractable sword installed in her forearm, in addition to steel angel wings. In the manga, however, she gets a massive sword that replaces her arm entirely. The other arm turns into an equally huge machine gun.
- Veronica in Franken Fran appears to be stuffed with spring-loaded weaponry. Given her Artificial Human nature, she may very well be literally full of weapons.
- Tengen Toppa Gurren Lagann does this with drills: the Gurren Lagann's usual weapon is a pair of drills coming out from above the wrist so in a sense it's also a Power Fist. Justified in that the Gurren Lagann can spawn drills from any part of it's body.
- Sango from Inuyasha has a hidden retractable blade in her right sleeve that she uses as a last resort.
- The ninja Hanzo in Hunter X Hunter has a retractable version. He uses it to threaten Gon during their fight in the final Hunter Exam.
- Edward Elric of Fullmetal Alchemist often uses alchemy to transmute his automail right arm into one of these blades, built in blades are also common for others with automail.
- Gundam 00 has the Gundam Exia, whose main weapon is a combination beam rifle and solid sword mounted on its right arm. Near the end of the series, its upgrade the 00 Gundam gets an improved version.
- Deadman Wonderland: Senji can create these out of his own blood.

- Nikolai Dante can turn his hands into swords thanks to his Weapons Crest.
- In X-Factor, sword wielding Shatterstar made a reappearance after a lengthy stay in Comic Book Limbo, sporting an updated look in an attempt to drag him out of the Dark Age. This new costume includes a leather jacket which covers a mechanism that houses blades on either side of his forearms. So he's actually got FOUR of these.
- Étienne Cazenac, the protagonist of the French comic La Croix de Cazenac, fights with knives (or, in one arc, shards of bone) tied to his wrists.
- Azrael (Jean-Paul Valley) has a version of this: Two flaming retractable Katar-like blades in his gloves. Said gloves look like giant gold fists, but...
- Debatable which category this would fit under, exactly, but in the X-Men comics mutant Marrow can and frequently does grow her bones out of her skin, break them off, and use them as blades.
- Post-Super Genesis Wave, Sally Acorn of the Sonic the Hedgehog comics wears a pair of bracelets called Ring-Blades that can project Laser Blades. They look a lot like the ones she had as Mecha Sally (see below).
- The Battle Butler Alfred in Hudson Hawk fights with a pair of retractable blades under his sleeves.
- Christian Szell, the White Angel of Auschwitz from Marathon Man, wears a spring-loaded blade in his sleeve to dispatch any concentration camp survivors who might recognize him.

- Karl Ruprecht Kroenen in the film version of Hellboy.
- Concept art for Star Wars Episode III featured a lightsaber gauntlet, with two blades attached to the user's forearms. The idea was eventually realized in toy form in The Clone Wars line.
- In A Nightmare on Elm Street Freddy Krueger's blade-fingered glove started out this way, when he was still alive and his glove, merely a homemade murder weapon. In dreams, it evolves into more of a built-in weapon, which alternately appears on his hand whole when he sheds a disguise, or sends its blades springing out from his (or a puppet's, or a possessed boy's, etc) fingertips. In Wes Craven's New Nightmare, a scene is filmed in which Freddy amputates his hand and replaces it with a razor-tipped robotic version, but this element doesn't seem to have carried over into the character's subsequent appearances. See also Wolverine Claws.
- Undercover Brother. During the final battle with Undercover Brother, Mr. Feather reveals short retractable blade claws that extend from below his sleeves.
- The Predators have retractable wrist blades that extend to a punching, slashing length. In some versions they become very long arm swords almost.
- Overlaps with the second category: the blades are retractable but are permanently attached. Removing them is fatal to the wielder.
- Abigail in Blade: Trinity has a small silver blade that springs from her wrist that she often uses for killing blows
- "Scream if this hurts, chica"
- Lucian in Underworld.
- Towards the climax of Batman, one of the Joker's mooks goes to dropkick Batman, while revealing blades hidden on his ankles. Batman's response is to simply punch him in the nuts.
- For added flavor, Batman doesn't use his fist; it's a contraption that springs out. A Ballbuster Below the Shoulder, you could say.
- Used most egregiously in Hook, when an entire sword (hilt and all) springs out of the Captain's sleeve, and into his hand.
- Affably Evil hitman Pasquale Acosta in Smokin' Aces uses a retractable stiletto to kill people.
- Lord Blackwood in Sherlock Holmes has a blade made of glass hidden in his sleeve. He attempts to stab Watson with it in the openning scene of the film, but Holmes shatters it with a truncheon.
- The eponymous psycho in Basement Jack trades in his machete for one of these, which was inexplicably in a suburban family's basement.
- The killer of The Final Terror favours one made from a billhook blade.
- At the end of Enter the Dragon, Han uses a Katara like weapon against Bruce Lee.
- In the miniseries The Stand, Dayna Jurgens tries to use a retractable blade tied to her arm and hidden in the sleeve of her nightgown against Flagg. He turns it into a banana.
- As seen in his self-titled spinoff, Angel has a set of retractable stakes that can pop out of his sleeves. Not blades, but just as effective, as evidenced by the piles of dust that used to be vampires. In the same series, Wesley uses a folding sword that pops out of his sleeve. He appears to hold it like a normal sword once its extended, though. When he loses his memory in one episode the practical problems of the concept are lampshaded, i.e. he nearly kills himself. And at one point, Connor shows up with an axe blade strapped to his arm.
- In at least one episode they're using forearm-mounted crossbows!
- Angel's retractable stakes became iconic for the series, remaining in the title sequence until the final season, and reappearing one last time (used by Gunn this time) in the Grand Finale.
- Apophis uses one in Stargate SG-1 in an attempt to kill Sokar. Though he failed, it's amazing he even got close enough to try, as said blade was a huge and very obvious device on his arm. He does manage to take out Sokar's First Prime and a Jaffa guard with it, though.
- Jean Renault in Twin Peaks. He uses it to kill a random strawberry and Blackie, the madam of One Eyed Jacks.
- The Stinger Blade wielded by the Blue Stinger Beetleborg is one of these.
- In Power Rangers Jungle Fury, Dominic the White Rhino Ranger's morpher is this, able to be summoned from a bracelet. The blade's handle is gripped in a fist-like fashion similar to a sword; however, the blade is aligned with the user's arm rather than being perpendicular. Known as the Rhino Blade, Dominic's weapon can also loose a powerful Super Slash finishing attack and also houses an alternate laser cannon mode.
- Merle Dixon on The Walking Dead has an interesting variant of this trope where the bayonet attaches to a prosthetic arm he wears over his right stump.
- The Warforged Armblade component in Eberron.
- In 4th Edition, any sort of one-handed weapon can be attached to a Warforged's arm. However, they function like type three model in that the Warforged can't actually do anything with that hand while the weapon is grafted onto it, although it can be removed voluntarily and fairly quickly.
- Actually, light weapons can retract into the Warforged's arm, if made with a specific type of attachment.
- Not just fourth edition, they could do it in 3.5 as well. All the rules were a bit byzantine.
- Quite the opposite problem, actually. No rules were given on how to make an item as an attached or embedded component, other than "you can."
- The Complete Scoundrel Splatbook for 3.5 has two arm blade options - sleeve blades like the kind in Assassin's Creed, reverse-facing elbow-blades, plus knee-blades, and boot-blades. You can even get blades hidden inside an instrument!
- Shadowrun gives us Forearm Snap-blades, which functions as an alternative to the more famous Spurs. These are meant for the runner who either doesn't have the cash for or doesn't want to deal with the Essence loss imposed by cyberware.
- The Melee weapon in Star Wars: Republic Commando is a miniature vibroblade mounted into the back of a clone commando's gauntlet. Crosses over slightly with type 2 because the blade is a part of the armor. It's very effective.
- In Advent Rising, the Aurelians have large, scythe-like blades attached just below the elbow - and pointing backwards. Their fighting style consists primarily of elbow jabs.
- The signature weapon of the Assassins in Assassin's Creed is the Hidden Blade, an extendable knife attached to an arm-brace used to silently kill enemies. In Assassin's Creed I, the ring finger of Altaďr's left hand is cut off in order to make this usable. His sequel successor (and descendant) Ezio on the other hand seems to have pulled this off (on both hands, even) without the nasty "cutting off fingers" catch.
- In game this is justified by having the base of Ezio's blade (inherited from his father) modified so it's raised further from the wrist, compared to the original design in Altaďr's day. This was actually Altaďr's idea — the first "Codex" page that's decrypted is his design for this blade, which another page implies that it's because hiding in plain sight ("social" stealth) is difficult with a missing ring finger — but Leonardo da Vinci would implicitly take credit for it. It doesn't stop him, however, from taking a moment to freak Ezio out by pinning his hand and raising a meat cleaver before saying "Just kidding."
- In Brotherhood the Prowler — a Templar attempt at fighting Assassins using their own methods — also has a forearm-mounted switchblade, if a wider and less fine-looking one, whose two blades pivot at the back to form a single blade in front. Ezio had to abandon the second (built by Leonardo, right-handed) of his Hidden Blades at the Siege of Monteriggioni, but had the original left-handed one replaced (or covered with a single-piece metal vambrace) upon his arrival in Rome, and Leonardo later constructed for him another right-handed Hidden Blade that now fit into the wrist of a leather glove.
- And in Revelations, Ezio loses his right-handed hidden blade again (the intro video shows him losing his left-handed hidden blade, but in gameplay he's missing the right-handed one) and has it replaced with one modified by the Assassins in Constantinople to have a hook on the end of the blade, allowing for more maneuverability when climbing and new abilities in combat.
- Each of Ezio's recruits in Rome was issued a Hidden Blade created by Leonardo da Vinci (as revealed in the Facebook game Project Legacy). By 2000 it had become "mostly ceremonial," but was still in use by the Assassins, and in fact Desmond Miles fought off a Templar invasion of an Assassin safehouse by wielding one.
- Governor Tekagi from Freelancer also has one of these.
- In Halo: Reach the Elites are issued with a wristblade, close to the Energy Sword. Gameplay-wise, it only appears during assassinations, since it's supposed to be the Elite equivalent of the Spartan's combat knife.
- Possibly Metroid Prime's Space Pirate grunts; it's not clear if they can take them off or not, but they don't actually replace the arm.
- It's unclear whether Weavel's blade in Metroid Prime Hunters is this or the "attached" variety, due to his cyborg status.
- The Assassin class in Diablo II: Lord of Destruction specializes in katar-type weapons.
- Street Fighter EX's Doctrine Dark wields a pair of retractable katars on the edges of his forearms that pop out below his wrists. Said blades have various lengths depending on D. Dark's special move/super combo.
- The Protoss Zealots in Starcraft have Energy Blades mounted in their armor. Dark Templar wield a single Warp Blade on their right wrist.

- The Garo in The Legend of Zelda: Majora's Mask have a scimitar strapped to each hand. Although they could be holding it under their ponchos, the attacks they use suggest otherwise.
- In the Overlord series green minions will convert weapons they pick up into blades attached to the backs of their hands (starting with two blades on only the right hand with very basic equipment, like farming tools and ending with three blades on each hand with the most powerful equipment).
- Rallen in Spectrobes has a sword as one of his optional weapons. It sucks, though.
- Rayne in the BloodRayne games wears sword-length blades attached to wrist cuffs; they mechanically rotate and extend in the same direction as her lower arms, with grips that she holds to keep them in place.
- Voldo from Soul Calibur's weapons include wrist-mounted motorized meat grinders, guillotine blades, pairs of antlers and regular katars.
- Dampierre's twin hidden daggers in Soul Calibur: Broken Destiny and also SoulCalibur V.
- World of Warcraft features "Fist Weapons" that can range from things that look like brass knuckles to full-arm sleeves featuring teeth, claws, spinning blades and/or other accessories.
- Big Sisters from BioShock 2 have a massive hypodermic needle which they use to impale enemies.
- In the Dark Storm mod for Cortex Command the Tengu armor guys use an electro-magnetic charged knife which is attached to their wrists (like the Assassin Blade in one of the above examples)in their melee attack, the knife was once a separate weapon in the mod up until lua's introduction in the game.
- Elites in Halo: Reach and the Arbiter at the time of Halo Wars both carry retractable Energy Swords in the armor on their wrists. Reach's Elites have small blades that only appear in assassinations while the Arbiter carries full-length swords on both arms.
- Kiros in Final Fantasy VIII uses a pair of katar (mistranslated in the English-language version as "katal").
- Annah of Planescape: Torment dual wields punch daggers, which she is very good at concealing. . .though how she could conceal much of anything in that outfit is hard to imagine.
- Tsuna from Otogi: Myth of Demons has one of these on his left arm as a secondary weapon.
- Mass Effect 3 brings us Omni-blades, diamond-hard searing hot blades flash-forged by one's omni-tool.
- Alex Mercer can change his arm into a giant blade from the shoulder down on command. It is sharp enough to slice through the toughest hides and metals including tanks at the cost of having to kill and consume hundreds of people to stay alive.
- James Heller and all the other Evolved that Mercer created in the second game also have this ability, more so with the other Evolved who, unlike Heller, seem to have just one special ability and dual armblades from the shoulder down.
- Sundowner, a cyborg boss from Metal Gear Rising: Revengeance fights with a pair of machetes, one of which he attaches to a hinged clamp on his forearm while holding the other in his hand, which turns his entire arm into a makeshift scissor with enough strength to decapitate any unfortunate soul in between the blades.
- In Champions Online, the Nephilim and PSI Mooks wear those. While the former can wear them even on their legs, the laters' are made of energy. Like many other costume pieces, blade bracers are unlockable and, despite being purely decorative, very popular amongst the players.
This is how IF, from 'Neptunia
'''s Qatars work.
- RWBY: Fox uses weapons that encase his hands and attach at his wrists. The blades are so long they extend backwards from his wrist to end somewhere behind his elbows.
- Coheed of the The Amory Wars has several curved blades along his left forearm.
- Kor'Maril in Drowtales has these to compensate for his height.
- Zeetha in Girl Genius uses a pair of swords with horizontal grips, similar to Katar (see below), which effectively extend over the tops of her hands.
- In Impure Blood, the Cyborg has this. Roan tears it off and kills him with it.
- Arminius Vambrey, a vampire hunter in Sluggy Freelance, conceals stakes in his sleeves. "And you thought these elbow pads just made me look tenured!"
- Waterworks features an entire alien race where each person has four long blades affixed to their legs and arms since birth, useful for all kinds of things. They're a major part of the culture, and losing one's blades or not caring for them properly is grounds for social stigma.
- A minor villain in Batman Beyond had retractable chainsaws in his wrists and knees. The latter proved to be a liability as they got stuck on walls and floors.
- Police chief Lin Beifong metalbends the bracers of her armored uniform into punching daggers to attack an Equalist Mini-Mecha on Episode 7 of The Legend of Korra.
- Kuvira makes a similar, segmented blade out of the metal in her own uniform during her duel with her former mentor Suyin.
- In the fourth season of The Venture Bros., 21 equipped himself with these, as well as developing some muscles.
- The Katar.
- As well as its larger cousin, the Pata.
- The wielder still has to hold both katar and pata. They're not attached to the arm; they're just held with a grip perpendicular rather than axial to the blade. That being said, they are almost certainly the inspiration for this kind of weapon in fiction.
- In reality, a blade like this would be impractical, both because the wrist joint is so important in the use of a sword and because it would be dangerous to the user. A hard blow to the blade could potentially cause the forearm to break.
- You could use it to stab people effectively, but no one ever seems to do that.
- Strap-on climbing spikes are sometimes used by professional tree trimmers or phone linemen to climb tree trunks and telephone poles. Subverted in that they're strapped to the legs, not the arms.
Type II (permanently-attached blade):
Anime and Manga
- Jeremiah Gottwald from Code Geass (pictured above). After having his body effectively rebuilt for the second time, he gains two concealed swords, one in each arm.
- As you can see from the picture, his blades are longer than his forearms. Given that the movement of his arms is in no way impaired with the blades retracted, and the blades clearly are not telescoping, it's unclear how this actually works.
- Taopaipai from Dragon Ball is rebuilt as a cyborg with this type of blade. He reveals it in his fight with Tenshinhan, using it to inflict the wounds that later become Tenshinhan's chest scars.
- The Guyver suit has two lethal blades attached to the forearms just in front of the elbows.

- In Fullmetal Alchemist, Ed can transmute his automail arm to use one of these in combat.
- Once Lan Fan gets an automail arm, her arm has a blade coming out of the elbow.
- It's a pretty common vampire power in Trinity Blood.

- Sasori from Naruto. He stuck his sword into Sakura's gut. Sakura planned on keeping him focused on her by holding onto the blade, thinking he wouldn't let go and would worry on just finishing her off first; then he detached his puppet limb to reveal a blade within it, and promptly went to finish off Chiyo. Didn't work out too well, he got stabbed right in the heart capsule by the first two puppets he ever created, the ones made in the likeness of his deceased Mother and Father. Then he died.
- Ikuro Hashizawa of Baoh fame. When in his "Baoh" form, he can brandish one on each arm, made of his own (albeit parasitic form) flesh. Said blades are known as "Reskiniharden Saber Phenomenon." He can even cut them off and throw them.
- Kars from Jojos Bizarre Adventure has blades on his fore arms that he can retract into his arms at will. They're sharpness is due to the fact that they double as chainsaws. He can also sprout blades from his legs. These are all also apparently a biological part of his body.
- It should be mentioned that Kars is an Expy of Ikuro (mentioned above) as both series had the same creator
- In the opening of the Hellboy feature movie that takes place in WWII, Kroenen first empties his sidearm on the Allied soldiers before he has arm blades pop out his sleeves, and begins to slice and dice the unfortunate GI's. Near the end, he retracts the blades back into his sleeves when forced to perform a different action.
- In one scene, Optimus Prime from the live-action Transformers movie uses a concealed sword in his right arm to attack Bonecrusher. He hated that.
- Wolverine has Wolverine Claws, as does Deathstrike in X2: X-Men United, only hers are rapiers of some sort.
- X-Men Origins: Wolverine:
Weapon XI has full length retractable katana blades in each arm. At least Wolverine's blades might've slid into his forearm allowing him to bend his wrist. This guy has no excuse. The blades are in fact so long that he shouldn't even be able to bend his elbow.
Sabretooth in the same film has Wolverine Claws, what with him being Wolverine's brother. They grow out of his fingernails and are shorter than Wolverine's, but clearly operate on the same principle.
- In Spider-Man 2, a stabbing blade is concealed within at least one of Doctor Octopus's Combat Tentacles, which appears from the centre of the claws when deployed. What purpose such blades had in conducting research on nuclear fusion is anyone's guess. Though it could have been added in after the fact, when he decided he had to do whatever it took to do what he set out to do.
- Kiryu, a.k.a. Mechagodzilla III from Godzilla Against Mechagodzilla, has a switch-blade sword in his right arm.

- One of the Ravenor novels has a throw-away character whose body has been heavily modified, with a blade like this being one of the additions. The character's hand split open, with the fingers forming a sort of grotesque guard, with the blade emerging from there. If that sounds like Squick then you really don't want to know what the new recurring character the scene introduced did to him.
- The Hork-Bajir in Animorphs are basically walking Cusinart, born with blades attached to their elbows, wrists, ankles, knees, tail and forehead (the poor mother...). Somewhat anticlimactically, they use them for gardening and harvesting bark from trees.
- Until some other aliens show up and parasitically possess them in order to turn them into a slave race of living superweapons.…

- The Yevetha, the antagonists of the Black Fleet Crisis trilogy, have retractable blades in their wrists. Depending on the artist, it's either a single blade out of the inside of the wrist or two blades out the sides.
- Model 0005 Cylons on Battlestar Galactica have retractable wrist-mounted blades for melee fighting. The newer Centurions instead have fingers that fold out into powerful claws.

All self-respecting street samurai will have at least one implanted weapon.
- In Warhammer 40,000, one piece of wargear available to Eldar are Power Blades, described as fitting onto the forearm and allowing the Eldar in question to wield other weapons in addition to the blades.
- The company Macrotech advertises their version of this as "perfect when guns are illegal and swords are too inconvenient" in GURPS: Bio-Tech.
- If we tried to mention all of the Bionic parts that granted this in Rifts, we'd be here all night. Not to mention the drills and chainsaws.
- BattleTech has this in the form of Retractable Blades, which are giant metal blades fitted onto the side of a mech's arm for stabbing through armor at close range.

- Raziel of Legacy of Kain gets a wraith-blade bound with himself. It extends from his open hand on command.
- At least until the last game, when it becomes a normal sword-shape. Boo.
- The Pokémon Gallade is an odd variant. Ordinarily, his arms don't even have blades, but when he enters battle, he can extend his elbows to make them Absurdly Sharp Blades. They become much more blade-like when Mega-Evolved.

- Serph from Digital Devil Saga, while in his demon form has two retractable blades protruding out of his forearms. At least they look to be part of his actual anatomy in that form.

- In the third season premiere of Transformers Animated, a newly-upgraded Sari Sumdac has a pair of energy-blades extending from within her forearms, though they are later permanently disabled and never seen again.
- Word of God (by which I mean Wyatt's formspring) is that they're still there, but their power output has been heavily reduced. Sari probably isn't too keen to use them again after what happened to Bumblebee.
- Second Transformers example: In Transformers Cybertron Starsceam's Cyber Key-activated weapons are a pair of arm-mounted blades. And in Episode 25, he uses them to great effect when he goes on a Foe-Tossing Charge through the entire Autobot army. One is eventually broken, and later replaced with a cannon.

Type III (blade replaces hand or arm):
Anime and Manga

- Eve in the same series usually morphs one of her hands into a blade to use as a Shapeshifter Weapon.

- The true form of Allen Walker's Innocence in D.Gray-Man is a BFS that is made from his arm. Different from the usual "third kind" of this trope in that the sword isn't attached to his body any more- he has to hold it in his remaining hand.
- Snimon from Digimon is a virus-hunting praying mantis sniper (mind you, all of that besides "praying mantis" is All There in the Manual and never witnessed, but he is pretty Badass) who cleaves opponents with its giant blades, and is capable of shooting pink crescent beams from them with its Twin Sickles attack (known as Shadow Sickle in Japanese. There's a badder version called Ultimate Twin Sickles, which increases the number of energy blades fired.) He's also one of the rare Mons who can overpower Digimon of higher levels than he.
- Omegamon/Omnimon's Transcendent Sword is technically this, since it comes out of his "hand" - which is composed of a WarGreymon skull/helmet instead of an actual hand with fingers. (Unlike Snimon, we don't have to worry about how he picks stuff up. This is a Fusion Dance Super Mode saved for special occasions and only taken on under dire circumstances. In his? Their? default form of Agumon and Gabumon, they've got hands, though Agumon doesn't appear to have thumbs.)
- Similarly, there's Duskmon. Like Omni/Omegamon, the blades are extended from his "hands" with are shaped like a pair of draconic skulls. Unlike Omnimon, he spends a great deal of time in this form, making one wonder how he held things other than "biting" them.
- Shurimon has giant shurikens for hands and feet, and his limbs are actually coils and are extendable. Again, combat form.
- One Piece's Axe-Hand Morgan...well, has an axe for a hand. A big one. Specifically his right forearm has been replaced with an axe, not even bothering to remove the handle, which can be seen stretching out the skin behind his elbow.

- In the original anime, Envy uses the same trick on Ed, except this time he/she kills him with it.

- Deconstructed in Accel World, where Kuroyukihime's avatar was generated with blades instead of arms due to her desire for power at the expense of human relationships. At one point she expresses regret that this means she can't embrace the Innocently Insensitive Haruyuki.
- Marvel Comics minor villain Razorfist, as the name implies, has two foot blades replacing each hand. The difficulty of, for example, eating are frequently lampshaded; Razorfist shirks all responsibility onto others to care for him (and they do because oh crap he is a crazy muscular martial artist with freaking swords for hands). This Razorfist is actually the second or third, depending on how you count it - he originally shared the name with his brother, each having only one blade-hand. He's so used to them that, whenever someone decides to replace them for prosthetic hands, he gets completely lost on how to use them.
- Razorsharp of The DCU team books Psyba-Rats and Blood Pack was a Playful Hacker (with Cracker tendencies) whose superpower was that her arms could morph into swords. In Psyba-Rats she mainly used them to climb walls and break into buildings (in a good cause, usually); in Blood Pack she was reluctantly put in a position where she'd have to use them in combat.
- The Avengers villain The Grim Reaper has a scythe blade on his right hand. Originally it was a Type One "techno-scythe" supplied by the Tinkerer. Later his right hand got amputated and replaced by a magical scythe when he was empowered by the demon Lloigoroth.
- Amokk, from Hyperkind, has his hands replaced with foot-long blades. In the second issue, he laments that he'll never play the guitar again, until he and the rest of the team discover that they can shapeshift back to their human forms.

- The 2007 Live-Action Adaptation of Dororo features the main character Hyakkimaru with two swords for arms, covered in magical sort-of living flesh that can be discarded like gloves as needed.
- In the third part of Piers Anthony's Battle Circle Trilogy, Neq the Sword, the titular character has his hands cut off by bandits. The surgeon who he rescued at the same time agrees to replace his left hand with a simple prosthetic claw, and his right with a sword. Unfortunately, his bad temper, coupled with a sword permanently attached to his arm, wind up causing unnecessary deaths. He remedies this by welding a glockenspiel to the sword so that it would never kill again. !

They were kept from escaping by having one hand chained to a wall while they worked. One day, Kargath decided he'd had enough, so he strangled his overseer with his chain and sliced off his manacled hand, replacing it with a blade. He then encouraged his fellow slaves to follow his example, and they rose up and killed their ogre masters.
- Starcraft: The recognizable Zerg Hydralisk has arms that end in huge scythe-blades that it cannot use in combat(although it does in cutscenes), because somebody was unable to incorporate meele and projectile attacks in one unit. However in Starcraft II it will be able to finally use those blades(however the attack is only cosmetically differnt from its normal attack).
- Also Starcraft has the Ultralisk which has two giant Kaiser Blades on its head.

- Space Pirate grunts in Metroid Prime 2 seem to have replaced one of their limbs with a blade.
- Although considering the Pirates are giant Flying Mantises, how do you distinguish their regular arms from blades?

- The Scrapers and the Missionary boss in Silent Hill 3 have blades for arms.
- Clive Barker's Jericho provides some especially horrifying examples in the form of the Cultist and Crusader-types of enemies.
- So do the Liars in Baroque; they like to thrust those blades into the ground and chase the protagonist with them.
- The player characters of Prototype and Prototype 2 are practically in love with this kind of weaponry. Three out of their five offensive powers involve turning their arms into bladed implements. The Claws ability "merely" grows oversized arms that end in foot-long, razor-sharp "fingers", the Whipfist produces an extendable tentacle with a razor end, and their iconic (and aptly named) Blade power turns the entire right arm into a big, honking sword of destruction roughly as big as themselves.

- The March Hare from Alice: Madness Returns sports one of these, but never gets to use it.
- In Mortal Kombat: Deadly Alliance, the demon Drahmin wields an iron club in place of his right hand and forearm (and it's always on the right).
- One of them happens in the SAW 2 Flesh And Blood video game, with a victim.
- In The Elder Scrolls IV: Oblivion, in the Shivering Isles expansion, we have the Gatekeeper, a sizeable Frankenstein-like monster guarding the entrance to the Isles. One of his arms is a giant blade. After killing the monster, we are tasked later on with putting him back together, using various body parts. For his arm, we can choose between the exact same blade and also an axe and a mace. The cut content suggests that there was also a regular fist to be included too...
- Generator Rex: one of Rex's favoured weapons, after the dual Power Fist, is to transmute his hand into a BFS.
- In Quest for Camelot Ruber does this towards the end with Excalibur with a magic potion that combines objects.
- Shiv, a supporting Static Shock villain, could replace his hands with nifty energy blades. If memory serves, this power was relatively versatile, but true to his name, he always came back to this...
- Optimus Prime again, this time in Transformers Generation 1, with an Energon axe in the three-part Series Premiere. Megatron had an Energon Mace. Despite using these weapons only that one time in the entire series, they're considered iconic to the characters, and even referenced by similar weapons in the movie listed above. Both of the characters Masterpiece series toys included plastic versions of the weapons. These were more of a combination of the second and third types, given that they retracted their hands to deploy them.
- Yet another Optimus: his Transformers Prime incarnation has two arm-blades and two arm-cannons. Both of Ratchet's arms can also become short swords ("I recommend dissection.")
- Not quite a blade, but a man named Aron Ralston who, after getting his arm trapped under a boulder for 5 days whilst mountain climbing, cut off his own arm to free himself, then proceeded to replace the amputated limb with an ice pick and climb the crap out of some more mountains. Chuck Norris himself would avoid this guy.
- Galvarino, war leader of the Mapuche tribe in the 16th century, was captured by the Spanish and had both his hands cut off to serve as a visual warning to the rest of his tribe. Because he was a total badass, however, he went back to the tribe, got them super-pissed at the Spanish, and then tied blades to his arms to compensate for the fact that he had no hands. He then proceeded to lead an army against the bastards who disfigured him. The Spanish ended up killing him eventually (they wanted to let him go because they felt sorry for him, but he would hear none of it), but it's important to note that the Mapuche tribe was one of the few that never fell under Spanish rule (it joined Chile in the 18th century).
