->''"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."''
-->-- '''Dr. Impossible''', ''Literature/SoonIWillBeInvincible''

It's common knowledge that [[CoolSword 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 [[SticksToTheBack 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 [[GlovedFistOfDoom make]] [[FlippingTheBird rude]] [[BicepPolishingGesture gestures]] to your opponent). This problem is intensified if the weapon user intends to [[DualWielding 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. Robots, [[HollywoodCyborg cyborgs]], and other non-[[BadassNormal regular human]] characters often take this one step further, embedding the blades inside their arms, from where they can be deployed and [[RetractableWeapon retracted]] [[UnusualUserInterface by thought alone]]. At the farthest end of the spectrum are characters who replace one or [[CripplingOverspecialization both]] of [[PowerFist their hands]] or even [[ArtificialLimbs their arms]] with large swords. This version is AwesomeButImpractical, as the blades prevent their wielders from performing mundane tasks when not in combat. They are also especially prone to [[FakeArmDisarm 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 [[RuleOfCool coolness]] or [[{{Badass}} badassery]].

WolverineClaws are a specific variant. May overlap with SwissArmyAppendage. Can be considered a subtrope of CoolSword. Compare its counterpart ArmCannon, as well as PowerFist. Not to be confused with {{Shapeshifter Weapon}}s, which are not limited to simply being blades. See also HookHand. Compare CombatHaircomb.

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'' a blade.

!Examples:

[[foldercontrol]]

!!First kind (removable arm blade):

[[folder:Anime and Manga]]
* Angel from ''Anime/AngelBeats'' has ''five'' of these as her first Guard Skill.
* A signature weapon of the titular character in BattleAngelAlita. The [[GratuitousGerman "Elbogen Blatt" style of "Panzerkunst"]] uses backwards-pointing blades attached to the "künstlers" forearms.
** Alita's blades become retractable after she gets the nanite-based Imaginos body.
* In ''DGrayMan'', the Inspector keeps a switch-blade sword hidden up his sleeve.
* Shooting Star Units from ''Manga/BlackCat''.
* Zagi from ''{{Jyu-Oh-Sei}}'' has one
* [=MagnaAngemon=] and Stingmon from ''Franchise/{{Digimon}}''.
* [[BubblegumCrisis Sylia Stingray's]] power armour has a pair of these attached to her wrists.
* [[{{Kurogane}} Jintetsu]] is equipped with a knife in his mechanical elbow. For some reason, he rarely uses it after the first volume.
* Sora of ''.Hack//Sign'', who has one on each arm. His are retractable and theoretically removable, but he never takes them off. In the .hack// games, Kite can also attain this type of weapon (even specifically named after Sora), though it's not his only one.
* In the anime, the RobotGirl Chachamaru from ''MahouSenseiNegima'' 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 ''FrankenFran'' appears to be stuffed with spring-loaded weaponry. Given her ArtificialHuman nature, she may very well be ''literally'' full of weapons.
* ''Anime/TengenToppaGurrenLagann'' 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 PowerFist. Justified in that the Gurren Lagann can spawn drills from any part of it's body.
* Sango from ''Manga/{{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 ''Manga/FullmetalAlchemist'' often uses alchemy to transmute his automail right arm into one of these blades, built in blades are also common for others with automail.
* ''[[Anime/MobileSuitGundam00 Gundam 00]]'' has the Gundam Exia, whose main weapon is a [[SwissArmyWeapon combination]] [[EnergyWeapons beam rifle]] and solid sword mounted on its right arm. Near the end of the series, its [[MidSeasonUpgrade upgrade]] the 00 Gundam gets an improved version.
* ''Manga/DeadmanWonderland'': Senji can create these [[BloodyMurder out of his own blood]].
* ''Anime/{{Casshern Sins}}'': Lyuze has a retractable blade in one of her arms, though her being a robot may mean it is permanent
[[/folder]]

[[folder:Comic Books]]
* The Gladiator, an adversary of Comicbook/{{Daredevil}}, uses wrist blades as a weapon of choice.
* Another {{Marvel}} villain, Whirlwind, supplements [[EverythingsBetterWithSpinning superfast spinning with wrist mounted sawblades.]]
* In the ''Sword of Azrael'' arc of ''Franchise/{{Batman}}'' the titular character's new outfit includes a retractable FlamingSword attached to one arm and a shootable one to the other.
* ''Franchise/TeenageMutantNinjaTurtles'': Although the precise number and location varies between incarnations, The Shredder's costume will always include several of these.
* [[ThoseWackyNazis Nazi]] villain Friedrich von Hassell has a retractable blade hidden in his sleeve in ''IndianaJones and the Tomb of the Gods''.
* NikolaiDante can turn his hands into swords thanks to his [[{{Cyborg}} Weapons Crest]].
* In ''Comicbook/{{X-Factor}}'', sword wielding Shatterstar made a reappearance after a lengthy stay in ComicBookLimbo, sporting an updated look in an attempt to drag him out of the DarkAge. 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}}'' ([[LegacyCharacter Jean-Paul Valley]]) has a version of this: [[DualWielding Two]] [[FlamingSword flaming]] [[WolverineClaws retractable]] Katar-like blades in his gloves. Said gloves look like giant gold fists, [[RuleOfCool 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.
[[/folder]]

[[folder:Film]]
* The BattleButler Alfred in ''Film/HudsonHawk'' fights with a pair of retractable blades under his sleeves.
* Christian Szell, the White Angel of Auschwitz from ''Film/MarathonMan'', wears a spring-loaded blade in his sleeve to dispatch any concentration camp survivors who might recognize him. The film illustrates the main drawback of the BladeBelowTheShoulder when Szell [[spoiler: [[KarmicDeath impales himself]] while tumbling downing the stairs.]]
* Karl Ruprecht Kroenen in the film version of ''Film/{{Hellboy}}''.
* Concept art for ''Franchise/StarWars [[Film/RevengeOfTheSith Episode III]]'' featured a lightsaber gauntlet, with two blades attached to the user's forearms. The idea was eventually realized in toy form in TheCloneWars line.
* In ''Franchise/ANightmareOnElmStreet'' 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 ''Film/WesCravensNewNightmare'', 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 WolverineClaws.
* ''Film/UndercoverBrother''. During the final battle with Undercover Brother, Mr. Feather reveals short retractable blade claws that extend from below his sleeves.
* The Franchise/{{Predator}}s 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 ''BladeTrinity'' has a small silver blade that springs from her wrist that she often uses for killing blows
** "Scream if this hurts, chica"
* Lucian in ''Film/{{Underworld}}''.
* Towards the climax of ''Film/{{Batman}}'', one of the Joker's mooks goes to dropkick Batman, while revealing blades hidden on ''his ankles''. Batman's response is to simply [[CurbStompBattle punch him in the nuts]].
* Used most egregiously in ''Film/{{Hook}}'', when an entire sword (hilt and all) springs out of the Captain's sleeve, and into his hand.
* AffablyEvil hitman Pasquale Acosta in ''Film/SmokinAces'' uses a retractable stiletto to kill people.
* Lord Blackwood in ''Film/SherlockHolmes'' 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 ''Film/TheFinalTerror'' favours one made from a billhook blade.
** At the end of Enter the Dragon, Han uses a Katara like weapon against Bruce Lee.
[[/folder]]

[[folder:Literature]]
* In Stephen R. Boyett's novel ''Architect of Sleep'', the soldier caste of the raccoon-like sapients wear a 'Fighting Hand', a bracer with a hinged plate that folds down to cover the back of the hand with a palm strap to keep it in place; the hinged plate has four daggerlike blades usable in close combat.
* Inigo Skimmer in the ''Literature/{{Discworld}}'' novel ''Discworld/TheFifthElephant'' had a blade cleverly concealed along his forearm(s), as well as a sharpened metal edge in his hat, and blades on his boots.
** He also might be the only character in the series shown to have any competence with wrist knives. In Discworld/NightWatch, Vimes remarks that even most Assassins think they're stupid and ineffective weapons.
** Inigo's blade is pretty much the [[Franchise/AssassinsCreed Assassin's]] Hidden Blade, which is extra funny because a) he is an actual Literature/{{Discworld}} Assassin and b) ''The Fifth Elephant'' precedes ''Assassin's Creed'' by several years.
* The Mantis Claw in ''ShadowsOfTheApt''. It's hinged, so there's even more mobility than the standard BladeBelowTheShoulder.
* In ''Literature/{{Hannibal}}'', Dr. Lecter arms himself with a spring-mounted concealed blade known as a Harpy. Available at any gun and knife show, apparently.
** It is, in fact, a [=SpyderCo=] Harpy. The spring-mounted bit is all Hollywood, though.
* Sten of the ''{{Sten}}'' series has a special knife sheath surgically implanted into his arm so he can carry a concealed blade at all times.
* ''Scythe-arms'' in Literature/ChroniclesOfTheKencyrath by PC Hodgell are [[DoubleWeapon blade pairs]] attached to the fore-arm, with the longer blade jutting forward and the other back. They are used in [[DualWielding pairs]], ie one main blade and one spur on each forearm. Training with them easily dissolves into chaos, with inexperienced users not being able to keep track of the spurs. Jame, the protagonist, is an exception, finding in them for the first time a weapon that she feels right with; she subsequently carries them everywhere.
* The Gutbuster Brigade in R. A. Salvatore's TheLegendOfDrizzt series. They wear bladed/spiked armor on which they regularly impale opponents, in addition to carrying massive axes or hammers. Their leader has been known to walk around with an entire hobgoblin impaled on his helmet, and to kill orcs by ''running into them chest-first and thrashing violently until the orc stops screaming.''
[[/folder]]

[[folder:Live-Action TV]]
* In the miniseries ''TheStand'', 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, Series/{{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 GrandFinale.
* Apophis uses one in ''Series/StargateSG1'' 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 ''TwinPeaks''. He uses it to kill a random strawberry and [[spoiler: Blackie, the madam of One Eyed Jacks]].
* The Stinger Blade wielded by the Blue Stinger {{Beetleborg|s}} is one of these.
* In ''Series/PowerRangersJungleFury'', 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 ''Series/TheWalkingDead'' has an interesting variant of this trope where the bayonet attaches to a prosthetic arm he wears over his right stump.
[[/folder]]

[[folder:Tabletop Games]]
* 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'' {{Splat}}book for 3.5 has two arm blade options - sleeve blades like the kind in ''Franchise/AssassinsCreed'', reverse-facing elbow-blades, plus knee-blades, and boot-blades. You can even get [[InstrumentOfMurder blades hidden inside an instrument]]!
* {{Shadowrun}} gives us Forearm Snap-blades, which functions as an alternative to the more famous [[WolverineClaws 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.
[[/folder]]

[[folder:Video Games]]
* The Melee weapon in ''VideoGame/StarWarsRepublicCommando'' 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 ''AdventRising'', the Aurelians have large, scythe-like blades attached just below the elbow - and pointing backwards. Their fighting style consists primarily of elbow jabs.
* In ''VideoGame/AssassinsCreedI'', Altaïr's Hidden Blade. Note that to make this blade usable, the ring finger of Altaïr's left hand is ''cut off''. His sequel successor (and descendant) Ezio on the other hand seems to have pulled this off (on [[DualWielding 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 Altaïr's day. This was actually Altaïr'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 ''[[VideoGame/AssassinsCreedBrotherhood 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 ''[[VideoGame/AssassinsCreedRevelations 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 ''VideoGame/HaloReach'' 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.
* Vega from ''Videogame/StreetFighterII''.
* Possibly ''VideoGame/MetroidPrime'''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 ''VideoGame/MetroidPrime Hunters'' is this or the "attached" variety, due to his [[WeCanRebuildHim cyborg]] status.
* The Assassin class in ''{{VideoGame/Diablo}} II: Lord of Destruction'' specializes in katar-type weapons.
** As does the assassin class in ''RagnarokOnline''.
* ''VideoGame/StreetFighterEX'''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 ''Videogame/{{Starcraft}}'' have [[LaserBlade Energy Blades]] mounted in their armor. Dark Templar wield a single Warp Blade on their right wrist.
* The punch dagger from ''{{Strife}}''
* The Sai faction in the game ''{{Stormrise}}'' have access to the Spectre unit type that fights with energy blades projected from it's forearms.
* With Weapons Customization, Arm Blades are offered in ''CityOfHeroes'' for the Claws powerset.
* Chipp Zanuff of ''VideoGame/GuiltyGear'' has an odd variant. His weapon is a blade that runs parallel to his forearm and is attached to a armband he wears there. In the opening animation, he sometimes clicks it into place
* The Garo in ''VideoGame/TheLegendOfZeldaMajorasMask'' have a scimitar strapped to each hand. Although they could be holding it under their ponchos, the attacks they use suggest otherwise.
* In the ''VideoGame/{{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. [[AwesomeButImpractical It sucks, though]].
* Rayne in the ''VideoGame/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 SoulCalibur's weapons include wrist-mounted motorized meat grinders, guillotine blades, pairs of antlers and regular katars.
** Dampierre's twin hidden daggers in ''SoulCalibur: Broken Destiny'' and also ''[=SoulCalibur=] V.''
* ''VideoGame/WorldOfWarcraft'' 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 ''VideoGame/BioShock2'' have a massive hypodermic needle which they use to impale enemies.
* In the Dark Storm [[GameMod mod]] for ''VideoGame/CortexCommand'' 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 ''VideoGame/HaloReach'' and the Arbiter at the time of ''VideoGame/HaloWars'' 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 ''[[DualWielding on both arms]]''.
* Kiros in ''VideoGame/FinalFantasyVIII'' uses a pair of katar (mistranslated in the English-language version as "katal").
* Annah of ''VideoGame/PlanescapeTorment'' [[DualWielding dual wields]] punch daggers, which she is very good at concealing. . .though how she could conceal much of anything in [[{{Stripperiffic}} that outfit]] is hard to imagine.
* Tsuna from ''VideoGame/OtogiMythOfDemons'' has one of these on his left arm as a secondary weapon.
* ''VideoGame/MassEffect3'' brings us Omni-blades, diamond-hard searing hot blades flash-forged by one's omni-tool.
* [[VideoGame/{{Prototype}} 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 [[spoiler:at the cost of having to kill and consume hundreds of people to stay alive]].
** James Heller and all the other Evolved [[spoiler: 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 ''VideoGame/MetalGearRisingRevengeance'' 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 ''ChampionsOnline'', the [[LightIsNotGood Nephilim]] and [[PsychicPowers PSI]] {{Mooks}} wear those. While the former can wear them even on their legs, the laters' are [[LaserBlade made of energy]]. Like many other costume pieces, blade bracers are unlockable and, despite being purely decorative, very popular amongst the players.
[[/folder]]

[[folder:Webcomics]]
* Coheed of the ''TheAmoryWars'' has several curved blades along his left forearm.
* Kor'Maril in ''{{Drowtales}}'' has these to compensate for his height.
* Zeetha in ''Webcomic/GirlGenius'' uses a pair of swords with horizontal grips, similar to Katar (see below), which effectively extend over the tops of her hands.
* In ''ImpureBlood'', the {{Cyborg}} [[http://www.impurebloodwebcomic.com/Pages/Chapter001/ib004.html has this.]] Roan tears it off and kills him with it.
* Arminius Vambrey, a vampire hunter in ''Webcomic/SluggyFreelance'', conceals stakes in his sleeves. "And you thought these elbow pads just made me look tenured!"
* ''Webcomic/{{Waterworks}}'' features [[spoiler: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.]]
[[/folder]]

[[folder:Western Animation]]
* A minor villain in ''WesternAnimation/BatmanBeyond'' 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 her cables into punching daggers to attack an Equalist MiniMecha on Episode 7 of ''WesternAnimation/TheLegendOfKorra''.
* In the fourth season of ''WesternAnimation/TheVentureBrothers'', 21 equipped himself with these, as well as [[TookALevelInBadass developing some muscles]].
[[/folder]]

[[folder:Real Life]]
* The [[http://en.wikipedia.org/wiki/Katara_(sword) Katar]].
** As well as its larger cousin, the [[http://en.wikipedia.org/wiki/Pata_(weapon) 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.
[[/folder]]

!!Second kind (permanently-attached blade):

[[folder:Anime and Manga]]
* Jeremiah Gottwald from ''Anime/CodeGeass'' (pictured above). After having his body effectively [[WeCanRebuildHim 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 ''{{Dragonball}}'' is [[WeCanRebuildHim 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.
* Gally/Alita from ''{{Gunnm}}'' had elbow blades during her Motorball days, and although they later got mounted on a blade for a time, Gally later recovered them in their implanted form with her Imaginos body.
* [[HollywoodCyborg Tre's]] Impulse Blades in ''MagicalGirlLyricalNanoha'' are [[LaserBlade energy blade]] versions of these that appear from her wrists.
** Also, Lutecia's [[BigCreepyCrawlies humanoid insect]] [[SummonMagic summon]] Garyu, who has many retractable blades in its arms.
* ''{{Mazinger}}'' series:
** ''Anime/MazingerZ'': In the last season, Mazinger-Z got equipped with the "Iron Cutter", two retractable blades stored in ''each'' arm. Often he used them in combination with its RocketPunch to slice enemies from far.
** At the end of the Creator/GoNagai manga, Sayaka got herself a new FemBot. One of its weapons were two blades attached tot he forearms it could shoot like a boomerang (joining this trope with RocketPunch and PrecisionGuidedBoomerang).
** ''Anime/UFORoboGrendizer'': Each fist of the titular mecha was surrounded by triangular blades pointed backwards. When Grendizer used its RocketPunch, those blades bent forward. So, the enemy was shredded being being punched.
* In ''Manga/FullmetalAlchemist'', Ed can transmute his automail arm to use one of these in combat.
** Once [[spoiler:Lan Fan]] gets an automail arm, her arm has a blade coming out of the elbow.
* It's a pretty common vampire power in ''TrinityBlood''.
* Both Kusanagi and the BigBad in ''BlueSeed'' can do this thanks to their mitama. They're retractable, but still apparently part of the body.
* [[BraveRaideen Akira Hibiki]]: '''[[CallingYourAttacks God Breaker! Gorgon Sword!]]'''
* ''Franchise/{{Gundam}}'' has a few examples all over TheVerse. The GM Sniper Custom has a box beam saber affixed to its left arm, while the [[Manga/MobileSuitGundamSEEDAstray Turn Delta]] has one on each arm.
** The RX-0 Unicorn Gundam from the ''[[Anime/MobileSuitGundamUnicorn Gundam Unicorn]]'' novels/{{OVA}} has two beam sabres mounted in its forearms (on flip-out panels) for use in this fashion, the MSN-06S Sinanju also has a pair.
** The GAT-X303 Aegis Gundam from ''[[Anime/MobileSuitGundamSeed Gundam SEED]]'' has a beam saber mounted on each of its limbs.
* The VF-27 "lucifer" in Macross Frontier, along with its cyborg pilot, Brera Sterne.
* Saiha's En Jin in ''FlameOfRecca'', which turns the [[FlamingSword main character's flame into a sickle-like blade]] that protrudes from his wrist.
* ''Anime/NeonGenesisEvangelion'': Sachiel, the first Angel does this with its arm bones.
* In ''Manga/KatekyoHitmanReborn'', [[PsychoForHire Varia]] officer Squalo has an artificial hand with a sword attached to it. The hand can be flipped to cover blind spots.
* Witchblade or Cloneblade users from ''Anime/{{Witchblade}}'' have extendable/retractable blades attached to their arms. The main character, Masane, has one, while those with [[spoiler: upgraded Cloneblades]] have two. [[spoiler: Masane acquires another one after learning to increase her power using the Witchblade]]
* [[MadArtist Sasori]] from ''Manga/{{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. [[spoiler: 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 ''Manga/{{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 "[[GratuitousEnglish Reskinharden Saber Phenomenon.]]" He can even cut them off and throw them.
[[/folder]]

[[folder:Comic Books]]
* Of course, [[WolverinePublicity we all know]] about [[{{Wolverine}} the short guy]] with [[WolverineClaws three in each forearm.]]
** And {{X-23}} by virtue of being his clone (she has two in each arm and one in each foot). And {{Daken}} by virtue of being his son (he has three on each arm, but one of them juts out through the front of his wrist).
* Also from MarvelComics, we have SquirrelGirl and her knuckle spikes.
[[/folder]]

[[folder:Film]]
* In the opening of the ''Film/{{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 ''HellboyII'', the [[KeystoneArmy golden army]] soldiers all have blades that pop out above their hands. Two of them, each made of [[AWizardDidIt red-hot gold]].
* In one scene, Optimus Prime from [[Film/{{Transformers}} the live-action]] ''{{Transformers}}'' movie uses a concealed sword in his right arm to attack Bonecrusher. [[MemeticMutation He hated that. ]]
** In the sequel, he gets to use [[DualWielding both arms]].
** Also, Sideswipe in ''RevengeOfTheFallen''. Damn, he's good.
* Wolverine in the ''Film/{{X-Men}}'' series has WolverineClaws, as does [[EvilCounterpart Deathstrike]] in ''Film/X2XMenUnited'', only hers are rapiers of some sort.
* Weapon XI in the film ''Film/XMenOriginsWolverine'' 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 WolverineClaws, 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 ''Film/{{Spider-Man}} 2'', a stabbing blade is concealed within at least one of Doctor Octopus's CombatTentacles, which appears from the centre of the claws when deployed. What purpose such blades had in conducting research on nuclear fusion is [[BellisariosMaxim anyone's guess]].
** Well, 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.
* [[Franchise/{{Godzilla}} Kiryu]], a.k.a. Mechagodzilla III from ''Film/GodzillaAgainstMechagodzilla'', has a switch-blade sword in his right arm.
* Franchise/RoboCop has a retractable spike that comes out of his right hand, which he uses to interact with machines - but ends up used as a weapon as well.
* ''Film/RoboGeisha'' provides an interesting take on this, as one of the many hidden weapons in the protagonist Yoshie's arsenal are a pair of retractable katanas that emerge from her ''arm pits''.
* ''Film/PacificRim'':
** Striker Eureka sports curved "Sting-Blades" attached to its forearms.
** Gipsy Danger has '[[WhipSword chainswords]]' in both arms.

* In ''SoonIWillBeInvincible'', Phenom has retractable blades surgically implanted in his arms.
* William Gibson's recurring razorgirl Molly Millions (from ''Literature/{{Neuromancer}}'' and ''Film/JohnnyMnemonic'') has retractable scalpel blades implanted in her fingertips.
* One of the [[TabletopGame/{{Warhammer 40000}} 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 ''Literature/{{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 Mantis-kinden in ''ShadowsOfTheApt'' often grow barbs down their forearms with their Art. They're most often used as a secondary weapon, though, adding one more way for them to kill you.
* The Yevetha, the antagonists of the ''[[Franchise/StarWarsExpandedUniverse 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.
[[/folder]]

[[folder:Live-Action TV]]
* Model 0005 Cylons on ''[[Series/BattlestarGalacticaReimagined Battlestar Galactica]]'' have retractable wrist-mounted blades for melee fighting. The newer Centurions instead have fingers that fold out into powerful claws.
* In the "Look At The Princess" episode trilogy of ''Series/{{Farscape}}'', the Peacekeeper agent Jenavian Charto has a stiletto blade concealed in her wrist.
* ''Series/MightyMorphinPowerRangers'': Rita's warzord Cyclopsis has twin wrist blades after being reconstructed by Lokar following the first time Ultrazord blew it up. It slices off one of the Megazord's arms and the [[ThisIsADrill drill tip]] of Dragonzord's tail. In Round 3, Dragonzord gets payback by using its tail to break the blades off.
* In ''Series/BuffyTheVampireSlayer'' Adam's demon arm had a retractable spike that extended from the base of the palm.
* In Gene Roddenberry's Series/{{Andromeda}}, the genetically modified Nietzscheans (Homo Sapiens Invictus) have bone blades in their forearms that can be extended and retracted at will.
[[/folder]]

[[folder:Tabletop Games]]
* {{Mortasheen}} has a few creatures with these, most notably [[http://www.bogleech.com/mortasheen/skoffix.htm Skoffix]].
* The Celestial series battlemechs in {{Battletech}} usually mount a large retractable blade on one arm.
* In Keith Baker's [[{{Eberron}} Dreaming Dark trilogy]] there is a Warforged named Indigo. She has two concealed blades in her arms.
* ''TabletopGame/{{Shadowrun}}'' offers hand razors, which are small blades implanted under the nails, hand blades, which extend along the outside of the palm and little finder, and spurs, which extend beyond the hand and can reach sword-like sizes. All self-respecting street samurai will have at least one implanted weapon.
* In ''TabletopGame/{{Warhammer 40000}}'', 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.
** Whereas SpaceMarine Terminators (and their [[FaceHeelTurn Chaos Marine]] counterparts) have the chainfist, a PowerFist (a giant mechanical glove that smites most things you can touch with it) with a [[ChainsawGood chainsaw strapped to it]] to make it [[NoKillLikeOverkill extra killy]].
** They also have [[ExactlyWhatItSaysOnTheTin lightning claws]].
** Members of the Black Dragon SpaceMarine Chapter often have retractable bone blades that grow from their forearms. They sheath them in adamantium to make them extra-effective.
* 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 [[ThisIsADrill drills]] and [[ChainsawGood chainsaws]].
* BattleTech has this in the form of [[{{BFS}} Retractable Blades]], which are giant metal blades fitted onto the side of a mech's arm for stabbing through armor at close range.
[[/folder]]

[[folder:Video Games]]
* The ''MortalKombat'' character Baraka is a member of the nomadic mutant Tarkatan race, most of whom possess long retractable blades extending from their forearms. Baraka is not an exception.
* Raziel of ''LegacyOfKain'' 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 ''Franchise/{{Pokemon}}'' 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 [[AbsurdlySharpBlade Absurdly Sharp Blades]].
** Given the shape of the arms in the game sprites, this could arguably be a combination of types 2 and 3.
** Earlier in the franchise, we have Sceptile and its Leaf Blade.
* Kunzite of ''VideoGame/TalesOfHearts'' has these as his prize for being the first playable robot in the Franchise/TalesSeries, ''and'' he gets the third kind as a bonus - two extra blades attached to flexible arms mounted on his back.
* HumongousMecha Soulgain from ''VideoGame/SuperRobotWars'' series has extendable blade on each forearms. Unextendable variant of said blades are used in EndlessFrontier by combat android Cardia Basirissa and Arkgain, a smaller combat robot based on the Soulgain.
* Jack in ''MadWorld'' has a retractable ''[[ChainsawGood chainsaw]]'' built into his bionic arm.
* Jehuty from ''VideoGame/ZoneOfTheEnders'' has an energized blade attached to its right arm. It runs along the forearm from the wrist normally, but swings to the front when engaged.
** Conversely, both Dolores in ''Dolores, i'' and Testament in ''Fist of Mars'' use Type 3 {{Morph Weapon}}s, with their entire forearms changing to a blade or ArmCannon when needed.
* In ''LostPlanet'', the [[HumongousMecha PTX-class]] [[AMechByAnyOtherName Vital Suit]] has a ''[[ChainsawGood chainsaw]]'' mounted on its left arm. That's right: A MiniMecha with [[GunsAkimbo twin]]-[[GatlingGood gatling guns]] and an arm-mounted ''[[ChainsawGood chainsaw]]''. Needless to say, they're the most powerful mechs in the game.
* [[SilentProtagonist Serph]] from ''DigitalDevilSaga'', while in his [[OurDemonsAreDifferent 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.
* Adam Jensen, the protagonist of ''VideoGame/DeusExHumanRevolution'', has two straight, square-tipped blades hidden in his bionic arms, which can extend either from the wrists or elbows, allowing him to take down enemies in awesomely over-the-top ways.
* Fulgore, a cyborg assassin in ''VideoGame/KillerInstinct'', has plasma charged blades mounted on his forearms.
* ''VideoGame/BloodyRoar'': Xion the Unborn has these in his beast form. His Primal Fury ending cutscene indicates that they're either in his human arms too or he can at least access them without transforming.
* Togera from ''WarOfTheMonsters'' extends spikes from its wrist during punch attacks, and Robo-47 replaces its hand with blades for some of its attacks.
* Alisa from ''VideoGame/{{Tekken}}'' can deploy [[ChainsawGood chainsaws]] from her arms while fighting.

[[folder:Western Animation]]
* In the third season premiere of ''TransformersAnimated'', 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.
** WordOfGod (by which I mean Wyatt's formspring) is that they're still there, but their power output has been heavily reduced. [[spoiler: Sari probably isn't too keen to use them again after what happened to Bumblebee]].
* Second Transformers example: In ''TransformersCybertron'' [[TheStarscream Starsceam's]] Cyber Key-activated weapons are [[DualWielding a pair of]] arm-mounted blades. And in Episode 25, he uses them to great effect when he goes on a FoeTossingCharge [[Awesome/{{Transformers}} through the entire Autobot army]]. One is eventually broken, and later replaced with a cannon.
* Arcee from ''WesternAnimation/TransformersPrime'' has two forearm-mounted blades, while Ratchet has retractable ones that can replace his hands when necessary.
** Optimus has the swords that debuted in the movies.

* Mantids (such as the Praying Mantis) actually have two of these facing opposite directions that act as pincers when the arms are extended.
[[/folder]]

!!Third kind (blade ''replaces'' hand or arm):

[[folder:Anime and Manga]]
* Creed's Phantom Blade Lv.3 in ''Manga/BlackCat'' replaces his arm with a Tao Blade and sprouts an extra arm.
** Eve in the same series usually morphs one of her hands into a blade to use as a ShapeshifterWeapon.
* Shira in ''BladeOfTheImmortal'', after losing a hand, decides to ''sharpen the bones in his arm'' and use that as a blade. Apparently, when he decided this he forgot to consider that it would hurt like hell to hit something with it. [[AxCrazy Like he'd care anyway...]]
* In ''Anime/{{Mai-Hime}}'', [[spoiler:RobotGirl Miyu]] can replace her lower arm with a sword ([[ArmCannon among other things]]).
* [[RobotGirl Chachamaru]] in ''MahouSenseiNegima'' carries one that replaces her standard arm along with an ArmCannon as seen [[http://www.mangafox.com/manga/mahou_sensei_negima/v21/c190/14.html here]]. How she goes back to her normal arms has yet to be seen.
* The ''{{Mazinger}}'' series:
** ''Anime/MazingerZ'': [[{{Robeast}} Mechanical Beast]] Brutus-M3 had a scimitar-like blade replacing one of its arms.
** ''Anime/GreatMazinger'': Several [[Robeast]] has bladed weapons -or even spiked maces- instead of hands or arms. The first examples appeared in the last episode of Mazinger-Z (Gratonios) and in the first episode of the sequel.
* The true form of [[spoiler:Allen Walker]]'s [[EmpathicWeapon Innocence]] in ''DGrayMan'' 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 ''Franchise/{{Digimon}}'' is a ''virus-hunting praying mantis sniper'' (mind you, all of that besides "praying mantis" is AllThereInTheManual and [[InformedAbility 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/[[DubNameChange 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 FusionDance SuperMode 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 [[EyesDoNotBelongThere 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.
* ''Manga/OnePiece'''s [[AnAxeToGrind 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, [[{{Squick}} which can be seen stretching out the skin behind his elbow]].
* ''Manga/SoulEater''. The bladed [[EquippableAlly Weapons]] can do [[http://www.mangareader.net/157-10195-40/soul-eater/chapter-50.html this]], with Death Scythes like Spirit [[spoiler: and Soul]] managing more varied transformations.
** [[spoiler: Maka can do this by the end of the anime.]]
* North Mk. II in ''{{Pluto}}'' has two of these.
* In ''Manga/FullmetalAlchemist'' example: One of the combat automail arms that Buccaneer uses over the course of the series, the "Crocodile", is this combined with a ''[[ChainsawGood chainsaw]]''.
** [[ShapeShifting Envy]] at one point turns its lower arm into a blade when fighting Ling.
*** In the original anime, [[spoiler: Envy uses the same trick on Ed, except this time he/she ''kills him with it''.]]
* Hyakkimaru, the main character of ''Manga/{{Dororo}}'' has swords concealed in his prosthetic arms, which slide off just below the elbow when he needs the blades. After he regains his real arms, he switches to wielding the swords as normal.
* Gray in GunsmithCats equips himself with a bladed prosthetic after Rally Vincent blows off his hand. He swaps the blade for a hook for everyday use. He can shoot the blade like a spear using a powerful spring built into the forearm.
* In {{Genzo}} the wild girl Otsuru uses a rusty blade as prosthetic right hand. Later the main character Genzo build a better curved blade for her.
* The gun-swordsmen from ''BrigadoonMarinAndMelan'' have one arm that ends with a blade instead of a hand, and another that ends with an ArmCannon.
* Solomon Goldsmith from ''BloodPlus'' shapeshifts one of this hands into a blade as a weapon of choice.
* Baroqueheat in HatenkouYuugi can [[http://www.mangafox.com/manga/hatenkou_yuugi/v02/c000/29.html change his right hand and forearm into a sword when he needs to.]]
* Gavrill from ''Manga/FrankenFran'', unlike her sister Veronica (Mentioned in Type 1 above), doesn't have blades inside her body, but is able to transform her body into, among other things, said blades.
[[/folder]]

[[folder:Comic Books]]
* MarvelComics 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 TheDCU team books ''Psyba-Rats'' and ''Blood Pack'' was a PlayfulHacker (with [[TheCracker 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.
* ''Comicbook/TheAvengers'' villain The Grim Reaper has a [[SinisterScythe scythe]] blade on his right hand. Originally it was a Type One "techno-scythe" [[WhereDoesHeGetAllThoseWonderfulToys 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 ''Comicbook/{{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.
* [[BatmanAndTheOutsiders The Outsiders]] once fought a villain named Nunchuku, who instead of hands, had, well... [[FightingWithChucks what do you expect]]? He was arguably one of the ''less'' silly opponents The Outsiders faced.

[[folder:Film]]
* ''Film/EdwardScissorhands'' has, well, blades instead of fingers.
* The blind Persian executioner in ''[[Film/ThreeHundred 300]]'' has swords instead of arms.
* Gigan from the ''Franchise/{{Godzilla}}'' movies has curved blades for forearms in ''Film/GodzillaFinalWars''. In his three previous appearances in the Showa series his hands were metal hooks.
* Cogliostro from ''{{Spawn}}'' can turn his arm into a glowing sword, or at least the movie version can.
* Ash from ''Franchise/EvilDead'', with his chainsaw hand. Groovy. Becomes the first type in ''ArmyOfDarkness'' when he gets a new [[PowerFist mechanical hand.]]
* In the made-for-TV movie adaptation of ''MobyDick'' (the one that stars Patrick Stewart as Captain Ahab), Ahab and crew meet up with another whaling ship, whose captain lost an arm to the white whale. He had it replaced with a harpoon.
* ''Film/WildWildWest''. When Jim West fights several of MadScientist Dr. Loveless's altered men inside the giant mechanical spider, one of them has extendable sword blades implanted in his arms instead of hands.
* In ''Film/ChildsPlay 2'', Chucky's hand is ripped off when a door closes on it. He then uses his remaining hand to stab his knife into the floor and remove the handle from the blade, and then ''[[BodyHorror plunges the blade into his arm stump]]''.
* ''Film/EnterTheDragon''. Han replaces his (false) hand with a torashuko claw in his iconic fight with BruceLee's character.
[[/folder]]

[[folder:Literature]]
* 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. !
* In ''TheMalazanBookOfTheFallen'', the K'Chain Che'Malle (Big intelligent lizard creatures) are bred for specific purposes, so the K'ell Hunters have big blades instead of claws or hands.
* The sword-armed man who was hunting Merlin in ''[[Literature/TheLostYearsOfMerlin The Wings of Merlin]]'', who lost his arms [[spoiler: when Merlin burned them off in a fit of angry PowerIncontinence during the prologue of the series]].
[[/folder]]

[[folder:Live-Action TV]]
* ''Series/MightyMorphinPowerRangers'' again: Some of the [[{{Golem}} Putty]] [[{{Mooks}} Patrollers]] had swords, axes, or blunt maces for hands. Also, the "Jaws of Destruction" monster had saw-hands which were soon severed.
[[/folder]]

[[folder:Video Games]]
* The Katana robot in ''OneMustFall'' has crescent-shaper blades instead of hands while the Shredder robot has claw-shaped cutters. In both cases the blades are monomolecular.
* ''{{Warcraft}}'': Kargath Bladefist, the leader of the Shattered Hand Orc clan, had a blade attached to his arm after he lost his hand. Replacing a limb with a blade became a popular rite of passage in his clan, hence the name Shattered Hand.
* ''{{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.
* In ''LeagueOfLegends'', new champion Urgot has one arm replaced with a blade, the other replaced with a [[ArmCannon CANNON]].
* Blade Golems in ''NeverwinterNights2'' including one controlled by the player.
* Both Protoman and Colonel in ''VideoGame/MegaManBattleNetwork''.
** ANY Sword Chip in the ''Battle Network'' (and ''VideoGame/MegaManStarForce'') series.
** Sword Man, in all his incarnations. In ''VideoGame/MegaMan8'', one of his hands is replaced with a [[OneHandedZweihander man-sized Zweihander]], while in ''Battle Network'', [[LivingWeapon his whole BODY is a sword in and of itself]].
* The forearms of the ''Franchise/{{Pokemon}}'' Kabutops take the form of curved blades.
** Scyther as well.
** And Gallade.
*** Gallade has fingers. The blades are on its elbows, like a Guyver.
** In the fifth generation, Pawniard and Bisharp have them. (being basically ''made of living blades'')
* In ''CityOfHeroes'', some members of the [[HollywoodCyborg Freakshow]] gang choose to replace ''both'' their hands with blades (or hammers). Flavor text mentions they rely on other gang members to feed them.
* Space Pirate grunts in ''VideoGame/MetroidPrime 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?
* Krauser in ''VideoGame/ResidentEvil4'' gains [[http://stealth125.webs.com/Krauser%5B1%5D.jpg this]] as a mutation when infected with [[TheVirus Las Plagas.]] Appropriately enough, considering he's an [[BloodKnight amoral]] KnifeNut.
* The Scrapers and the Missionary boss in ''SilentHill3'' have blades for arms.
* ''VideoGame/CliveBarkersJericho'' provides some especially horrifying examples in the form of the Cultist and Crusader-types of enemies.
* So do the Liars in ''VideoGame/{{Baroque}}''; they like to thrust those blades into the ground and chase the protagonist with them.
* The player characters of ''VideoGame/{{Prototype}}'' and ''VideoGame/{{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 [[WolverineClaws foot-long, razor-sharp "fingers"]], the ''Whipfist'' produces an [[WhipSword extendable tentacle]] with a razor end, and their iconic (and aptly named) ''Blade'' power turns the entire right arm into a [[{{BFS}} big, honking sword of destruction roughly as big as themselves]].
* One of [[VideoGame/{{Xenosaga}} KOS-MOS's]] many, many abilities.
* Blade Man from ''VideoGame/MegaMan10'' has swords instead of hands. AND his head.
** What a ''tour guide'' would do with all those swords though, [[SuperPoweredRobotMeterMaids we will never know]].
* In ''VideoGame/MetalArmsGlitchInTheSystem'', the Troopers not only DualWield these in replacement-for-the-hand form, but they [[ArmCannon do the same]] with plasma blasters and combine them with the blades ''[[GunsAkimbo on the same arms]]''.
* The enemy type in ''TheSuffering'' which symbolises execution by decapitation not only has forearms replaced by blades, but the legs below the knees too. Don't ask how it manages to maintain balance when running.
* The March Hare from AliceMadnessReturns sports one of these, but never gets to use it.
* In ''MortalKombatDeadlyAlliance'', the demon Drahmin wields an iron club in place of his right hand and forearm (and [[AmbidextrousSprite it's always on the right]]).
* One of them happens in the SAW2FleshAndBlood video game, with a victim.

* ''GeneratorRex'': one of Rex's favoured weapons, after the dual PowerFist, is to transmute his hand into a {{BFS}}.
* In ''QuestForCamelot'' [[spoiler: Ruber does this towards the end with Excalibur]] with a magic potion that combines objects.
* Shiv, a supporting ''StaticShock'' 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 ''Franchise/TransformersGeneration1'', with an [[LaserBlade Energon axe]] in the three-part Series Premiere. Megatron had an Energon [[EpicFlail 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 ''WesternAnimation/TransformersPrime'' incarnation has two arm-blades ''and'' two [[ArmCannon arm-cannons]]. Both of Ratchet's arms can also become short swords ("I recommend dissection.")

[[folder:Real Life]]
* 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. ChuckNorris himself would avoid this guy.
* [[http://www.badassoftheweek.com/galvarino.html 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).
