[[caption-width-right:246: ''[[SerratedBladeOfPain Jagged]]'' black sword, even better!]]

A {{Fantasy}} trope, but can show up in other genres as well. Want to show that some kind of sword is cool, powerful, deadly, etc? Make this sword black. It can be simply [[http://en.wikipedia.org/wiki/Bluing_(steel) blued]], but sometimes it is made of some fantasy metal which is naturally black. [[ThunderboltIron Meteoric iron]] is often misrepresented as a naturally black metal. (It actually doesn't look all that different from terrestrial iron, once forged and worked.)

This trope often overlaps with EvilWeapon and ArtifactOfDeath, because the color black has connotations for being "{{dark|IsEvil}}" as well as "cool." Many examples of black swords are not only superior to boring gray swords, but also more dangerous for the user.

If the sword's owner likes to DualWield, their other sword [[YinYangBomb will often be white]].

Compare ThunderboltIron, TechnicolorBlade, and FlamingSword. Also note that [[KatanasAreJustBetter black katanas are even better]], [[WoodenKatanasAreEvenBetter wooden black katanas are absolutely better]], and [[FlamingSword flaming]] [[NinjaPirateZombieRobot wooden black katanas are downright awesome]].

!!Examples:

[[foldercontrol]]

[[folder:Anime & Manga]]
* ''Manga/{{Bleach}}'':
** The Bankai form of Ichigo's Zanpakutou is an entirely black tachi with a manji-shaped hilt. [[spoiler: His true Zanpakutou is completely white in Asauchi form but in Shikai becomes two jet black swords.]]
** The fourth movie set in Hell has the Togabito weapons, Kokuto's sword (pictured) and Muragumo's glaive, which are pitch black.
* ''Manga/OnePiece'' has two black swords so far: [[{{BFS}} Kokuto Yoru]], the strongest sword in the world, owned by the strongest MasterSwordsman Mihawk. The other one is [[KatanasAreJustBetter Shusui]], a long katana with an elaborate black blade currently owned by Zoro. Is listed as one of the strongest swords in the world, and Zoro even stated that it wouldn't bend even if a dinosaur stepped on it. Mihawk also demonstrates to Zoro that, by using Haki (spiritual power), any weapon can be made black and greatly stronger.
* Guts of ''Manga/{{Berserk}}'' fame wouldn't be the Black Swordsman without that [[{{BFS}} huge sheet of black blade]] that he calls the Dragonslayer.
* ''Manga/SamuraiDeeperKyo'' has the Shibien, one of the four swords crafted by Muramasa. It apparently absorbed too much blood and turned black as a result.
* Saizo from ''Manga/Brave10'' has one. [[ICallItVera He calls it the Mari Blade]].
* ''Manga/SoulEater''
** Masamune ''is'' [[EquippableAlly one]] and after Tsubaki defeats him she gains this ability as well. Slightly subverted when Tsubaki, during hers and Black★Star's battle against Masamune, claims that now that's black the blade has lost some of its original beauty.
** Also Ragnarok, being entirely made of "black blood". Since he's the Demon Sword, he's one of the most powerful weapons in the series.
* ''Franchise/BlackRockShooter'' wields the ''black blade'' (the ''★rock shooter'' part of her name is for her [[{{Handcannon}} gun]]).
* In ''Manga/{{Yaiba}}'', the Devil King Sword is black colored with white edges.
* In ''Manga/{{Fairy Tail}}'', Erza uses a black sword in her Purgatory Armor.
* In ''LightNovel/SwordArtOnline'', Elucidator, one of Kirito's two swords, is pitch black. In ALO, his sword is also black. In GGO, his sword is '''still''' black. And go on, guess what color his sword in Underworld is going to be. There's a reason he's called the Black Swordsman in that series.
** Worth mentioning that, as mentioned in the DualWielding example, in SAO his second sword is white...though only in the original light novel.
** And in Mother's Rosario [[RedBaron Zekken]][[note]]A moniker earned from a 67 duel win streak[[/note]], the only person to defeat him, has a black sword. Kirito also says that Zekken would have gotten the DualWielding[[note]]Given to the player with the highest reaction speed[[/note]] sword skill were he in SAO.
* In ''Manga/MagiLabyrinthOfMagic'', Sharrkan's sword is pictured as this. Alibaba's new sword is subverted; [[spoiler:the ones who have black color is its sheathe.]]
* In ''LightNovel/{{Campione}}'', Ena Seishuin's legendary sword Ame no Murakumo no Tsurugi is black.
* ''LightNovel/FateZero'' has [[spoiler:Arondight]], Berserker's personal weapon. It's black, spiky, with crisscrossing chains on the hilt, and generally looks pretty evil. In fact, it's said to be as powerful a demonic sword as Excalibur is a holy one. Not only that, but using it gives Berserker a rank up in all his stats, raising him from 'fearsome' to 'borderline broken'. Black swords aren't just better, they make you better too!
* In ''Manga/MagicalGirlLyricalNanohaInnocent'', Lord Dearche can summon [[StormOfBlades a storm of black blades]] with her Legion of Doom Bringer spell. When she first uses it to destroy every target in the game she's participating in one fell swoop, Arisa wonders if what she's using is still legal.
* In ''LightNovel/ChivalryOfAFailedKnight'', Ikki Kurogane's Device takes the form of a black katana called Intetsu.
* Ayato Amagiri from ''LightNovel/GakusenToshiAsterisk'' wields the purple-black blade, Ser Veresta which was previously owned by his elder half-sister [[spoiler:Haruka Amagiri.]] He has an astounding 97% compatability rate with it.
* In ''LightNovel/AestheticaOfARogueHero'', Akatsuki Ousawa wields the giant sword Laevateinn which is colored black. It requires seven AD's to generate, unlike just one for everyone else. [[spoiler:By putting on eight AD's, the sword becomes bigger, sharper, and gains a massive axe-like blade head on top of it.]]
* In ''LightNovel/SeireiTsukaiNoBladeDance'', Kamito Kazehaya's contracted spirit, Restia transforms into a jet-black demon sword known as Vorpal Sword in her elemental waffe form.
* Lux Arcadia from ''LightNovel/UndefeatedBahamutChronicle'' has the Black Divine Drag-Ride Bahamut which is color black when in sword form. It was originally owned by his elder half-brother [[spoiler:Fugil.]]
* Kanata Age in ''LightNovel/KuusenMadoushiKouhoseiNoKyoukan'' was formerly known as the Black Master Swordsman. He wields the black magic cannon sword Gladius as his main weapon of choice. It can shoot powerful laser beams by consuming his magic power.
[[/folder]]

[[folder:Comic Books]]
* The Black Knight's Ebony Blade from Creator/MarvelComics. Another example of ThunderboltIron. It can cut through anything and fire energy beams, but if it's used "in an unworthy manner," it fills the wielder with an uncontrollable bloodlust.
* {{Inverted|Trope}} in ''ComicBook/CerebusTheAardvark''. Part of the layers of [[Literature/TheElricSaga Elric]] parody in the character Elrod of Melvinbone is that his sword Seersucker is black because of ''rust''. When Elrod tries to attack Cerebus with it, it shatters against Cerebus' sword.
* All-Black the Necroblade, wielded by ''Comicbook/TheMightyThor'' villain Gorr the God Butcher. Finding the sword is what allowed a poor starving mortal to butcher gods. The sword grants power over darkness and turns its wielder into a PhysicalGod.
* The first UsefulNotes/{{Muramasa}} sword in ''ComicBook/{{Wolverine}}'' comics. Like the Ebony Blade, anyone else than the one born to wield it would have uncontrollable bloodlust.
[[/folder]]

[[folder:Literature]]
* The two swords, Anguirel and Anglachel (later renamed as Gurthang), made by Eöl the Dark Elf, in ''Literature/TheSilmarillion''. These swords were made of meteoric iron, which is not naturally black, and ''Literature/TheSilmarillion'' predates the popular concept of "meteoric iron is naturally black", so they must be blued. Confirmed by an early version of Gurthang in ''Literature/TheBookOfLostTales''--it is black on the flat, with shiny edges. This, however, may be the origin of the black meteoric iron misconception.
* In Creator/MichaelMoorcock's ''[[Literature/TheElricSaga Elric of Melniboné]]'' series of novels, the two demonic runeblades, Mournblade and Stormbringer, the latter of which becomes Elric's iconic weapon, are black. This one is so iconic that it inspired three heavy rock songs - Music/BlueOysterCult's "Black Blade", Music/DeepPurple's "Stormbringer" and Music/{{Hawkwind}}'s "Chronicles of the Black Sword."[[note]]In this case not just a single song - a whole multi-media stage performance and a concept LP[[/note]] If it were merely grey, would it have got this attention?
** Though Stormbringer is most famous, in Moorcock's mythology of the Eternal Champion, it is but an incarnation of a multiversal entity that is used and uses the Eternal Champion in many incarnations, an entity that is outright called the Black Sword. The Black Sword also manifests in its purest form when the Champion incarnates as Urlik Skarsol.
* C'threk Goru, the sword of the Dark God Torak in the {{Belgariad}}, is explicitly black, of unnamed material, and is the counterpart to Garion's Sword of the Rivan King, which is made of ThunderboltIron. In the sequel series the Malloreon, the sword is wielded again by a demon lord in the final confrontation.
* ''Literature/ChroniclesOfTheEmergedWorld'': Nihal's black sword is actually made from a {{mithril}}-like substance called "Black Crystal", which is a ludicrously hard crystal.
* Creator/LloydAlexander's ''Literature/{{Chronicles of Prydain}}''. The black sword Dyrnwyn is extremely powerful. It was used to kill not only all of the Cauldron Born but the Big Bad Arawn himself. It was originally a beautiful shiny sword until its wielder slew an innocent shepherd with it. The shepherd's blood stained the blade, turning it black.
* Nightblood of ''Literature/{{Warbreaker}}'' is a black sentient [[TalkingWeapon telepathic]] sword that suggests killing just about everybody. Also it can compel just about anybody to kill their companions and themselves; its most common use is being thrown into groups of enemies who end up killing each other off. Ironically it was actually created to destroy evil, but a sword doesn't know what evil is so it tries to get its owner to kill people just in case... [[spoiler:Eventually, it is [[Literature/WordsOfRadiance removed]] to [[Literature/TheStormlightArchive Roshar]] and is given to the hands of [[NeverMyFault Szeth]]-[[ProfessionalKiller son]]-[[PsychoForHire son]]-[[ManInWhite Vallano]].]]
* One of the three magical swords of ''Literature/MemorySorrowAndThorn'' is black (Thorn). Another is silver and the third a dull, somewhat mottled grey.
* The Morganti weapons in ''Literature/{{Dragaera}}'' are black blades that [[SoulCuttingBlade eat the souls]] of their victims. Foremost among them are the seventeen Great Weapons, which are [[EmpathicWeapon self-aware]], have unique properties, and are powerful enough to kill the Gods. Merely unsheathing the Great Weapon Blackwand can make a battalion break and flee: the sword is even more of a BloodKnight than its wielder.
* Kring from the first Literature/{{Discworld}} novel ''Discworld/TheColourOfMagic'' is probably a parody of Stormbringer. In concept, a jet black, magically sentient blade that can talk and grant the wielder combat prowess (even when they're not looking) is very cool. In practice, Kring's habit of droning on in a tinny metallic monotone that sounds like metal grinding over stone, not to mention constantly critiquing its owner, means that most warriors tire of it quickly.
* The title weapon of ''Literature/TheDarkswordTrilogy'', which [[AntiMagic consumes magic]].
* In ''Literature/ASongOfIceAndFire'', Valyrian steel is described as having a dark, swirling, smokey appearance. Weapons made from it are sharper, stronger and lighter than traditionally-made steel. Since it's of such high quality and nobody knows how to make it anymore, weapons made from it are extraordinarily valuable and typically owned only by wealthy nobles.
** Inverted, however, with Dawn, the ancestral sword of house Dayne forged from ThunderboltIron. It's described as ''milky white'' in color, and yet is at least as good as a Valyrian steel sword.
* Nico from ''Literature/PercyJacksonAndTheOlympians'' has a sword made from black Stygian Iron from TheUnderworld.
* The sword Dragnipur in ''Literature/TheMalazanBookOfTheFallen''.
* The Sword of Leah from Creator/TerryBrooks' ''Literature/{{Shannara}}'' series. Once an ordinary sword, it was dipped in the waters of the Hadeshorn by the Druid Allanon, and then infused with a measure of the Druid's own magic. The result is an ink black blade with a liquid sheen, and pools of green swirling through it that devours any magic directed at the user.
* ''Literature/AWizardInRhyme'': Matthew Mantrell wields a black diamond sword, at least for the first two books. Not much mention is made of it later in the series.
* The Rain Master's Flamberge, [[spoiler: a.k.a. the Sword of Humanity and part of the same set as the titular artifacts]] in ''Literature/DiamondSwordWoodenSword'' is both very powerful and cursed. Its other name is ''the'' Black Sword.
* Draken-Korin, BigBad of the original ''[[Series/RiftwarCycle Riftwar]]'' quartet carries a black sword to go with his orange-and-black striped armour. Since his title is Lord of Tigers, this makes sense.
* In ''Literature/MistbornTheOriginalTrilogy'', Mistborn don't use metal knives because of their enemies' SelectiveMagnetism powers. Instead, they favor knives of obsidian.
* The titular weapons of the ''Literature/BlackBlade'' series, which absorb magic.
[[/folder]]

[[folder:Live-Action TV]]
* In ''Series/KamenRiderDragonKnight'', Wing Knight is the only Kamen Rider besides Eubulon to carry a black sword and both... kick... a lot of ass.
* During the season 2.5 finale of ''Series/{{Nikita}}'', Alex buys a combat knife with a black blade. Quite {{justified|Trope}}: see RealLife, below.
[[/folder]]

[[folder:Music]]
* In Music/SoundHorizon's "Moira," Elefseus uses two triangular black swords. Other characters, such as Sword Boy, also use a black sword. In almost all the cases the sword(s) seems to carry some sort of significance, linking the characters.
* Creator/MichaelMoorcock's ''[[Literature/TheElricSaga Elric of Melniboné]]'' inspired three heavy rock songs - Music/BlueOysterCult's "Black Blade", Music/DeepPurple's "Stormbringer" and Music/{{Hawkwind}}'s "Chronicles of the Black Sword."[[note]]In this case not just a single song - a whole multi-media stage performance and a concept LP[[/note]]
[[/folder]]

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons'':
** The game has weapons made of special materials. Most of them just allow the weapon to bypass a particular type of damage resistance (i.e. silver weapons work against werewolves), but weapons made of Adamantine are [[NighInvulnerability exceptionally hard to destroy]], [[AbsurdlySharpBlade can cut through metal as easily as (equivalently thick) paper]], ''and'' bypass a particular type of damage resistance. They're black.
** There's also the ninth-level Arcane spell, [[http://dndtools.eu/spells/magic-of-faerun--20/black-blade-of-disaster--1605/ Black Blade of Disaster]]. It bypasses magic barriers, attacks on its own, and disintegrates anything it crits. ''TabletopGame/ForgottenRealms'' only, sorry.
* The magus base class from ''TabletopGame/{{Pathfinder}}'' has an optional archetype where they forge a bond with a sentient magical black sword. It is very [[Literature/TheElricSaga Elric-y]].
* ''{{Exalted}}'' has [[PoweredByAForsakenChild soulsteel]] - a pitch black metal made from the tortured, still-aware, souls of humans that can drain a persons essence and willpower away when used as a weapon. While not necessarily better than the other magic materials, it's still better than normal metals. Characters could also acquire weapons made from 'Black Jade', which gave good bonuses to defensive stats. One such weapon was a dagger called ''Black Depths Foretold'', which was fated to kill a powerful God...despite various attempts to [[YouCantFightFate throw it away]].
* In ''TabletopGame/Warhammer40000'', the Sword of Secrets, the Sword of Silence and the Raven Sword (collectively known as the Heavenfall Blades), are three of the Dark Angelís most prized relics. These master-crafted power swords are said to have been forged from a single block of jet-black obsidian, originating from a meteorite that had struck the Dark Angelís Fortress-Monetary of the Rock.
[[/folder]]

[[folder:Video Games]]
* In ''VideoGame/UltimaUnderworld 2'', the best type of sword is a black sword. Likely a callback to ''The'' Black Sword from ''VideoGame/UltimaVII''.
* When you finally assemble the Nobitsura Kage in ''[[VideoGame/ShadowWarrior2013 Shadow Warrior]]'', the weapon looks like the blade was forged from obsidian with lava-cracks running through it. It's the most powerful weapon you get ([[EleventhHourSuperpower though you only get to play around with it at the very end of the game]]) and fires off {{Sword Beam}}s that cut through the crowds of enemies running at you, and has a high rate of fire. It's also the only thing that will kill an Ancient, since the Ancients are otherwise immortal.
* In ''VideoGame/TheLegendOfZeldaSkywardSword'', the BigBad, Ghirahim, has a black rapier (and later, two) in the second phase of each fight against him. [[spoiler:Turns out that Ghirahim himself ''[[EquippableAlly is]]'' a sword, belonging to Demise, which resembles a black and bulkier version of the Master Sword]].
* In ''Franchise/TheElderScrolls'' series of video games, Ebony and Daedric weapons (the best nonmagical weapons) are not exactly black, but close enough to count (ebony is a dark metal, while Daedric weapons are ebony weapons with the soul of a daedra bound to them and tend to be some combination of red and black).
** And there is also Umbra in ''Oblivion'', though it's an eerie bone white in ''Morrowind''.
* ''VideoGame/RuneScape''
** Black swords are a weapon category, above steel and below mithril, uncraftable.
** There's also Darklight, which was created when the sword Silverlight was coated in ichor while destroying the demon Agrith-Naar. It is stronger than the original Silverlight and is extra effective at killing demons.
** And then there is the [[http://runescape.wikia.com/wiki/Dominion_sword Dominion sword]].
* In ''VideoGame/FableI'', obsidian weapons are better than iron or steel ones, and second only to 'master' (grey metal with gold trim) among non-legendary weapons.
* The InfinityPlusOneSword in ''VideoGame/BaldursGateDarkAlliance'' is jet black.
* In ''VideoGame/JadeEmpire'', the weapon of choice for Prince Sun Kin is a large black sword called the Demon Sword, which is also available to the Spirit Monk in the PC version. Death's Hand dual-wields a black sword in his main hand and a black dagger in his off-hand, as well. [[spoiler: Considering that Death's Hand is really Prince Kin's soul bound to Sun Li's old armour, this is not a coincidence.]]
* Black Knight weaponry from ''VideoGame/DarkSouls'', unlike other bladed weapons, is colored jet black. There is a reason for this though, as the lore says Black Knights were charred by a highly powerful magical flame such that they were burnt to ashes and their armor and their weapons went black from the heat. As for their power, the weapons (large sword, great sword, great axe, and great halberd) were not even originally meant to kill man, but gigantic Demons. Saying that they are powerful is an underestimation at best.
** The Cursed Greatsword of Artorias is a decent greatsword that is one of the few weapons that can permanently kill ghosts.
* Black Knight weapons return in ''VideoGame/DarkSoulsII'', though they seem to be a bit rusted due to age. Despite that, they are still very powerful weapons. The Crypt Blacksword, crafted from [[spoiler:the Soul of the Old Dead One dropped by The Rotten on NewGamePlus which is heavily implied to be the soul of Gravelord Nito]], is a jet-black {{BFS}} that is potentially one of the most powerful weapons in the game.
* In ''VideoGame/INinja'', the player regularly receives upgraded swords whose colors correspond to karate kyu and dan. In order of increasing superiority, the swords are colored white, yellow, green, blue, red, black.
* ''VideoGame/FalloutNewVegas'' has an unusual example in that it's black ARMOR that's better. The Veteran Ranger Combat Armor, 200 year old riot gear that serves as the main armor for the NCR Veteran Rangers and also called [[ExactlyWhatItSaysOnTheTin the black armor]], is the game's iconic armor, appearing in nearly all promotional materials. The fact that it has the highest defense of nearly every armor short of PoweredArmor reinforces this. This is taken UpToEleven in Lonesome Road, which has the [[AceCustom Advanced and Elite Riot Gears]] that provide special effects alongside the high defense.
** In the same theme, the strongest PoweredArmor is the black colored Enclave Armor.
* In ''Fallout'' and ''Fallout 2'', various Envclave R&D projects had created stronger [[PoweredArmor Power Armor]] for their troops such as the Advanced Power Armor Mk. I & II [[note]]The mk I version returns as the Remnant Armor in New Vegas [[/note]], and Frank Horrigan's Power Armor. ''Fallout 3'' has the the Tesla Armor and later the Elite Hellfire Armor in ''Broken Steel''.
* ''VideoGame/PokemonXAndY'': The shiny coloration for the possessed sword Aegislash is black and red.
* The ''Franchise/FinalFantasy'' series has seen the Dark Knight class in various entries, which can arm Dark Swords. In ''VideoGame/FinalFantasyIII'', the Dark Sword is the only weapon that can permanently kill otherwise regenerating enemies.
** ''VideoGame/FinalFantasyIV'' gives Cecil a black sword called the Deathbringer for his final weapon as a Dark Knight. Not only is it black, it has a chance to cause instant death on whatever it hits.
* ''VideoGame/MightAndMagic VIII'' has Glomenthal, the Blade of Dark, which has a blackish brown blade. It's one of the best artefact blades in the game. It's also completely bereft of any restrictions on the morality of the user.
* In ''VideoGame/BravelyDefault'', the InfinityMinusOneSword of the Swords category, the Night Emperor, is black with white trim.
* When sufficiently upgraded, Corvo's balisong sword in ''VideoGame/{{Dishonored}}'' becomes black.
* In ''Videogame/OdinSphere'', Oswald the Shadowknight's Belderiver is a jet-black sword that is considered the most fearsome Psypher ever forged. Oswald's own foster father Melvin sold Oswald's soul to Queen Odette of the Netherworld to empower it, though this is offset by the sword being powerful enough to fight off Odette's agents the Halja, meaning they can't actually collect on the deal [[spoiler:until Oswald drops the Belderiver in a bout of despair.]] In gameplay, the sword's power grants Oswald his [[SuperMode Shadow form]].
* In ''Videogame/PhantomBrave'', Sprout once wielded the Sacred Sword. After his family was killed by Sulphur, he went mad with grief and lived only for revenge. He decided to fight darkness with darkness, and absorbed dark energy from the various monsters he encountered. Eventually, his once beautiful Sacred Sword became a pitch-black blade of darkness, Shiva.
* Naotora Ii wields one in ''Videogame/SengokuBasara'' 4.
* In ''VideoGame/NuclearThrone'', by leaving Chicken's starting weapon (the Chicken Sword) in area 1-1 and then looping the game, the aptly named [[ExactlyWhatItSaysOnTheTin Black Sword]] will spawn near you. This weapon swings faster than most other melee weapons in the game, and while it doesn't have too much base damage (12 per hit), it has the ability to deal ''80 damage per hit''... [[DesperationAttack if Chicken is headless.]]
* In ''VideoGame/VampireTheMasqueradeBloodlines'', the Tal'mahe'Ra Blade is a black {{katana|sAreJustBetter}} forged in a ghost-city of TheUnderworld by an ancient vampire cult; it deals [[WoundThatWillNotHeal aggravated damage]] which, like [[KillItWithFire fire]] and [[WeakenedByTheLight sunlight]], cuts through vampires' defenses and interferes with their HealingFactor.
[[/folder]]

[[folder:Visual Novels]]
* In ''VisualNovel/UminekoWhenTheyCry'', both [[GreatDetective Willard H. Wright]] and [[RealityWarper Bernkastel]] have black blades. Given in VisualNovel/UminekoWhenTheyCry, colour is ''incredibly'' important, the colour of these weapons is far more than just cosmetic, giving them powers to attack ideas and metaphysical concepts directly. Oh, and fitting Bernkastel's [[GoodPowersBadPeople personality]], her black blade takes the form of a SinisterScythe that can reap miracles.
* Played with in ''VisualNovel/FateStayNight''. In the ''Heaven's Feel'' route, [[spoiler:Saber turns evil due to TheCorruption that's been attacking the Servants, and to match her new "Saber Alter" state her golden sword Excalibur turns black. While the sword itself is not inherently stronger than the original Excalibur, it ''is'' far deadlier, if only because Saber Alter is now receiving infinite mana from the corruption, and can thus use her sword's devastating SwordBeam function almost infinitely (beforehand, the SwordBeam used by the good Saber had to be used with restraint due to its high mana consumption).]]
[[/folder]]

[[folder:Web Comics]]
* In ''Webcomic/{{Goblins}}'', Minmax touches a PowerCopying sword to a hole in reality, which turns it black and gives it the PowerOfTheVoid: it vanishes from reality when he's not using it, is unaffected by any physical force other than him wielding it, and appears to bypass monsters' usual resistance to damage.
* In ''TabletopGame/DungeonsAndDragons'', cold iron weapons are especially effective against demons. In ''Webcomic/TheOrderOfTheStick'', they're black; examples include [[http://www.giantitp.com/comics/oots0409.html Hinjo's awesome katana]].
* ''Webcomic/{{Homestuck}}'' features [[{{Portmanteau}} the Regisword]], and various other weapons [[JustAddWater combined with it]]. It appears to be a ceremonial piece, though most of the characters using it are skilled enough to use it effectively anyways.
* In ''Webcomic/TheRedStar'', the GrimReaper [[http://www.beyondrealitymedia.com/the-red-star/issue-3/page-22/ uses a black scythe]].
[[/folder]]

[[folder:Web Original]]
* Wiki/SCPFoundation'': SCP-076-2 can summon bladed weapons made of a mysterious non-reflective black material.
* In ''Series/{{Noob}}'', Omega Zell eventually upgrades to weapons that are [[KatanasAreJustBetter not only a pair of katanas]], but a pair of black katanas. He actually points out the color to another character some time after getting them.
[[/folder]]

[[folder:Western Animation]]
* Sokka's sword, also made of [[ThunderboltIron meteoric iron]], in the third season of ''WesternAnimation/AvatarTheLastAirbender''.
* In the ''WesternAnimation/SamuraiJack'' episode "Jack and the Ultra-Robots", the last Ultra-Robot uses a black katana.
* [[ProudWarriorRaceGuy Pre Vizsla]] from ''WesternAnimation/StarWarsTheCloneWars'' wields a black-bladed lightsaber as his melee WeaponOfChoice.
[[/folder]]

[[folder:Real Life]]
* Many blades designed for modern military use or survival are painted black or blued so they don't give away their owner's position by reflecting light. The bluing also prevents rust.
* The sharpest manufacturable blades are made of obsidian, which is a black glass (they have an entry under AbsurdlySharpBlade).
* A steel cutting tool (such as a knife or machine tool head) with a layer of Titanium Carbonitride deposited upon it will have a glossy, very dark gray finish. It'll also hold its edge longer and much more resistant to corrosion and wear by way of a bonus.
* At one point, civilizations capable of creating the much darker steel (from which the term ''black''smith came from) ''is'' this trope, especially if their neighbors were using the comparatively inferior bronze weapons.
* [[http://en.wikipedia.org/wiki/Damascus_steel Damascus steel]], while not black, is ''much'' darker than normal steel, and thanks to unique impurities in the metal is also far stronger than any other form of steel humans were capable of making up until the industrial era.
