Absurd Cutting Power is the ability to slice and dice things that would normally be able to resist being cut. There are any number of ways to achieve this -- technology, magic, extremely high-quality blades, or an incredibly skilled character doing the cutting are all possibilities. Usually involves lots of {{Clean Cut}}s and {{Single Stroke Battle}}s. Expect to find that LikeCannotCutLike -- something with absurd cutting power usually won't be able to cut something ''else'' with absurd cutting power.

[[folder:Anime And Manga]]
* In ''Manga/FullmetalAlchemist'', the homunculus Lust's "ultimate lance" ability extends her fingers into long blades which can cut perfectly cleanly through anything, even though they are clearly 3/4 of an inch thick for most of their length.
** Pride's shadows can cut or pierce just about anything - and under normal lighting conditions, they can reach just about ''anywhere.''
* In ''SaintSeiya'', Shura's Excalibur (the strongest weapon of the saints, which can cut through anything, be it flesh, armor, attacks or dimensions) consists of.... his limbs, most frequently his arm. Yes, it is imbued with cosmos, but it's still an arm.
* In ''Manga/{{Naruto}}'', turning any weapon into one of these, or creating one out of chakra, is one of the most basic uses of Wind Style.
* ''Anime/DragonBallZ'''s Z-Sword [[SubvertedTrope subverts]] this. Everyone ''thinks'' the reason it's legendary is because it's impossibly sharp and unbreakable, but it turns out to be [[SealedGoodInACan something else entirely]].
* Many swords in ''{{Yaiba}}'' are really, really sharp. Justified, because they're magical.
* In ''Manga/OnePiece'', this is true for almost all swordsmen. For example Mihawk can do this, partly because he is the best swordsman in the world and also because his sword is absolutely huge.
* Kazuma in ''LightNovel/KazeNoStigma'' does this with RazorWind, effortlessly slicing through buildings as if he was cutting cheese with an industrial laser.

[[folder:Literature]]
* Creator/LarryNiven's short story "Not Long Before the End" (a part of his ''Literature/TheMagicGoesAway'' universe) features Glirendree, "the most powerful sword in the world". It can cut through anything and makes its wielder immune to all magic. On the other hand, it is also a parasitic demon forced into the shape of a sword that leeches its user's life away, giving him no more than about a year of glorious victory before killing him of old age.
* In LinCarter's ''Dragonrogue'', the hero, Kesrick, has a sword that, because of the magical gem in the pommel, can cut anything -- even adamantium.
* The eponymous Literature/SwordOfTruth can cut through anything that its wielder perceives as an enemy -- and unless you can find the strength to kill something you love will not touch an ally. Here, at least, it's explicitly magical. Needless to say, it's dangerous in the wrong hands.
* In Literature/TheTaleOfTheFive novels by Creator/DianeDuane, when Segnbora is literally at death's door, she acquires a sword made by her ancestor from a fragment of that door, named Skadhwe. Skadhwe can literally cut through anything and lacks both a hilt and a flat (and is implied to have a will of its own), which would be a problem in wielding. So Duane adds the exceptions of "not its current owner", and "not anything its owner doesn't want it to cut", making Skadhwe probably the most convenient and least scary example of this trope.
* In the TabletopGame/ForgottenRealms there is the sentient sword Khazid'dhea, a blade that wants nothing more than to be wielded by the greatest swordsman there is (and to prove this by having said swordsman kill every other swordsman in the world). It is telepathic and can reshape its hilt to its owner's desires and incidentally inspire its wielder into a berserker frenzy if it gets bloodthirsty enough. It can also take chunks out of stone and never needs sharpening. Its name means, in the Drow tongue, "Cutter".
* The three Swords of the Cross in the ''Literature/TheDresdenFiles'' are absurdly sharp, on top of being indestructible, having incredible holy power, and being the focus of the Knights' even stronger abilities. At one point Dresden decides to test out one of the Swords by dropping drinking straws on it; their own weight makes it shear cleanly through them.
** Also displayed by the Warden's swords - Warden Ramirez cleanly cuts the throat of one villain, and it takes a moment before the damage is even visible, and they are also used a couple of times to cut through magic, although this may be a separate ability, and have nothing to do with the sharpness of the edge.
* The subtle knife from ''Literature/HisDarkMaterials''. One side is so sharp it can slice though any matter effortlessly, including [[ThunderboltIron Sky Iron]]. The other side is so sharp it can slice through the boundaries separating other dimensions. Both edges are so thin and sharp that the end of it can't be seen with the naked eye. It also comes with a special scabbard, which really just holds the grip well.
* In ''Discworld/{{Wintersmith}}'' the sword Roland uses to kill the bogles is literally made out of sharpness.
* Shardblades in ''Literature/TheStormlightArchive'' can cut through anything non-living except [[LikeCannotCutLike other Shardblades]] and [[PoweredArmor Shardplate]] as easily as passing through air. It doesn't cut through living flesh, but instead "kills" any extremity it passes through by severing its connection with the rest of the body, making it paralyzed and useless. If it passes through a vital part of the body, the victim is killed instantly -- [[EyeScream burning out their eyes]] in the process. The exact mechanism for this is as of yet unclear, but it's implied that Shardblades [[SoulCuttingBlade cut the soul]] instead of the flesh.
* In Neal Stephenson's ''Literature/TheDiamondAge'', the nanosword that Nelly, the female protagonist, creates. It is capable of cutting through almost any material.

[[folder:Video Games]]
* The Keyblade in ''Videogame/KingdomHearts''. Even the Kingdom Key, which has a blunt edge, can cut through buildings in ''VideoGame/KingdomHeartsII''. [[KiAttacks The explanation is that the actual blade is the magic around it, thus, no matter how blunt it may look, the weapon cuts like a well-crafted sword.]] Some keyblades, though, have explicitly sharp heads, and are basically fancy axes (and the original InfinityPlusOneSword, Ultima Weapon, was a sword with a strange guard around the blade).
* Anna's {{BFS}} from ''VideoGame/ManaKhemiaAlchemistsOfAlRevis'' can somehow cut open ''reality'', allowing her to enter other dimensions for her special attacks.
* Sanger Zombolt's Zankantou from "VideoGame/SuperRobotWars" can cut through pretty much anything. Mechs of both human and alien origin, giant flying battleships, even a mountain formed for the purpose of pulling off a CombinationAttack. The man said it himself, there is nothing his blade cannot cut.

[[folder:Webcomics]]
* In ''Webcomic/GunnerkriggCourt'', the Coyote Tooth. "The keenest blade you will ever find! Be careful with it, because it could cut the very earth!" . Annie and Kat "[[http://www.gunnerkrigg.com/archive_page.php?comicID=966 did some tests on it]] and found it to be '''really''' damn sharp". That is, they sliced through a steel beam like it was butter, and dropped a steel bearing on the edge and it continued the fall in two pieces. [[spoiler:After Parley accidentally cuts Robot in two with it, it peels Shadow off the floor when she drops it]].
