A character in a work finds a weapon, and discovers that it is the same weapon from one of the [[OralTradition legends]] of their world. Most of the time, legendary weapons are a pretty big deal - they don't call them "legendary" for nothing, after all - and instead of being a ''very'' [[ExcaliburInTheRust old, rusty piece of scrap]] that's been in a display case for the last millennium, are actually extremely powerful and useful. They might even have the spirit of an ancient hero trapped in them, have immense magical properties, or be made with [[LostTechnology a technique that has been lost to the ages]]. Occasionally, when the protagonist is TheChosenOne of a Fantasy setting, they'll just happen to be a descendant of the last great hero to use that weapon, and the weapon will unlock its true power only in their hands.

Usually a {{Named Weapon|s}}. Since having the protagonist find a legendary weapon at their local store is a bit silly, the weapon tends to be a SwordOfPlotAdvancement that is rather hard to acquire.

Please note that this is for ''legendary'' weapons, meaning that the weapon [[FamedInStory has to be part of the legends and history of the work]]. This is not a trope for just any ancient weapon or CoolSword the protagonists find, or weapons in a work that happen to share a name with a PublicDomainArtifact.

SuperTrope to AncestralWeapon. Contrast PenultimateWeapon and DayOldLegend. See also InfinityPlusOneSword, InfinityMinusOneSword, ExcaliburInTheRust, CoolSword, and SwordOfPlotAdvancement. If the work's setting is based on the real world, it may overlap with PublicDomainArtifact.

[[folder: Anime And Manga ]]

* Excalibur in ''Manga/SoulEater'' is considered the strongest of weapons (which, in this setting, is a race) and his power is considered the stuff of legend. Any Meister who wields him is pretty much unstoppable, and many have tried, as his location and exploits are well documented. [[spoiler: What isn't, is the fact that he is completely insufferable and no one can stand him long enough to use him for long.]]
* Most of the Servants' [[SignatureMove Noble Phantasms]] in ''VisualNovel/FateStayNight'' count. Considering the setting is based on the real world and the Servants are actually spirits of legendary heroes, a lot of them overlaps with PublicDomainArtifact.

[[folder: Film ]]

* Mjolnir in ''Film/{{Thor}}''.
* The sword Green Destiny in ''Film/CrouchingTigerHiddenDragon'', an AbsurdlySharpBlade famously wielded by Li Mubai and which serves as a MacGuffin for much of the movie.

[[folder: Literature ]]

* In ''Literature/TheLordOfTheRings'', Narsil is the legendary sword that was forged in the First Age by a famous dwarven smith, wielded and broken by Elendil and then used by Isildur to cut the ring out of Sauron's hand at the end of the Second Age, and then reforged under the name Andúril at the end of the Third Age to fulfill one of the ancient prophecies.
* Early in ''Literature/TheHobbit'', the party recovers a small treasure hoard from some trolls. Among the hoard are a pair of legendary elvish blades, Orcrist the Goblin-Cleaver and Glamdring the Foe-Hammer, two legendary swords forged millennia earlier by the elves of Gondolin. Thorin Oakenshield takes Orcrist [[spoiler:and it's eventually buried with him]], while Gandalf takes Glamdring and uses it several decades later to kill the balrog in ''The Fellowship of the Ring''. Notably, these blades are also legendary among the ''goblins'', who call them Beater and Biter and recognize them on sight; pretty impressive considering they haven't been in use for hundreds if not thousands of years.
* Several of the 13th century [[Literature/TheIcelandicSagas Sagas of Icelanders]] (specifically ''Kormak's Saga'' and ''Laxdoela Saga'') have a cameo of Skofnung, the legendary sword of the ancient Danish king Hrolf Kraki told about in ''Literature/TheSagaOfHrolfKraki'', which supposedly was [[GraveRobbing robbed from Hrolf's gravemound]] and brought to Iceland by the Icelander Skeggi of Midfirth.
* ''TheRiftwarCycle'': The Hammer of Tholin is an ancient weapon that belonged to the last king of the dwarves, believed to be lost to the ages. The lore attached to it is so strong that its recovery allows [[spoiler: Dolgan]] to become the first king of the dwarves since its loss.
* The Sword of Shannara from the ''Literature/{{Shannara}}'' series is the legendary sword which the Elven King Jerle Shannara used to defeat the Warlock Lord and end the Second War of the Races. Five hundred years later, the entire plot of ¡¡Literature/TheSwordOfShannara'' is a quest for said sword.
* The Sword of Godric Gryffindor and the Elder Wand in ''Literature/HarryPotter''.

[[folder: Live-Action Television ]]

* ''Series/{{Tracker}}'s'' Strada Brac. [[note]]note that as the series ended just after its discovery, we still have no idea how it's spelled for certain. This spelling is a fan consensus[[/note]] It was the subject of Vardian and Cirronian legends about how it was made during an ancient war and then stolen by the Migar council and hidden on Earth to keep it away from the Vardians. By the modern era, most of their peoples believed it was simply a myth. Cole and Mel obviously proved them wrong.
* ''Excalibur'' in ''Series/{{Merlin}}'' which Arthur is going to rip out of that stone as revealed by the series trailer, and Lancelot's sword which I have momentarily forgotten the name of.

[[folder: Music ]]

* The Emerald Sword in the ''RhapsodyOfFire'' songs. Very old, extremely powerful, can also count as an UnholyHolySword.

[[folder: Tabletop Games ]]

* ''TabletopGame/DungeonsAndDragons'' has had many of these, from the Axe of the Dwarvish Lords and Sword of Kas in the 1st Edition Dungeons Master's Guide to the swords of the ForgottenRealms as described by Ed Greenwood (Adjatha, Albruin, Demonbane, etc.).

[[folder: Video Games ]]

* Any weapon (or, indeed, any item) that unlocks a [[EncyclopediaExposita Codex]] entry in the ''Franchise/DragonAge'' series. Additionally, if you acquired the weapon Vigilance in ''[[VideoGame/DragonAgeOriginsAwakening Awakening]]'', the epilogue mentions that it went on to become one of these.
* The Runeblade from ''[[VideoGame/{{Drakan}} Drakan: Order of the Flame]]'' belonged to Heron, the last great dragonrider and is also the [[InfinityPlusOneSword best weapon in the game]].
* The [[CoolKey key]][[CoolSword blade]] in ''VideoGame/KingdomHearts''.
* ''VideoGame/KingdomOfLoathing'' parodies legendary weapons at every turn.
** There's a chain of quests where the player gets a series of legendary weapons. First, the player has to [[DayOldLegend create the "Epic Weapon" for their class]]. Following that, they obtain more ingredients and upgrade it to the "Legendary Epic Weapon". Following that, the weapon gets transformed into the "Ultimate Legendary Epic Weapon" when fighting the next boss.
** There's Trusty, Boris' trusty axe which the player is forced to use when playing as the Avatar of Boris.
-->''Not every magical weapon is forged of meteorite iron under an unusual planetary conjunction, inscribed with gilded runes of ancient power, and imbued with supernatural strength and sharpness through mystical rites and sorcerous incantations. In truth, many of the most powerful weapons of lore are possessed of far humbler beginnings -- common metal, torn from an enemy's grasp in a dire emergency. If the warrior survives the day, the weapon will likely be kept. Polished, sharpened, and re-sharpened, it will be carried from battle to battle, becoming as much a part of the man as his own arm, and as his name rises from warrior to hero to legend, so too will an aura of reverence and awe begin to surround the blade. Legend and belief are powerful forces, and it should be no surprise that a powerful artifact might have become powerful simply by dint of everyone believing it to be powerful. That is, after all, where the gods came from. ''
* ''Franchise/TheLegendOfZelda'': [[SwordInTheStone The Master Sword]], aka, "The Sword of Evil's Bane", is as legendary as the Triforce itself. It is inscribed in Hyrule's lore that evil ones cannot touch it, nor can anyone, save for the [[TheChosenOne Chosen Hero]] draw it from the Pedestal of Time.
* The Sword of Mana from the ''VideoGame/WorldOfMana'' series. Even ''more'' legendary because it is [[IHaveManyNames ALL the legendary swords that have ever existed, just with different name on each occasion]].
* ''VideoGame/FinalFantasyV'' has the twelve legendary weapons. They are weapons. They are legendary. There are even twelve of them.
* The Vampire Killer Whip in ''Franchise/{{Castlevania}}'' series is considered the ultimate undead-killing holy weapon.
* The Eternal Sword in the ''Franchise/TalesSeries''. Also known as the Sword of Time, it is capable of cleaving time and space itself.
* ''VideoGame/{{Warcraft}}'': Frostmourne (among others).
* In ''VideoGame/TitanQuest'' the most powerful weapons and items are the "Legendary" or "Mythological" ones.
* ''VideoGame/NeverwinterNights2'':
** The Silver Sword of Gith, an AncestralWeapon of the githyanki and githzerai forged by Zerthimon for Gith to free them from the mind flayers. In the backstory it was lost in the Nine Hells, then recovered by [[WellIntentionedExtremist Ammon Jerro]] to fight the [[BigBad King of Shadows]], during which battle it was shattered. Its shards act as {{Plot Coupon}}s to allow the blade to be reforged.
** Another legendary weapon from the first campaign is the Hammer of Ironfist, the AncestralWeapon of your companion Khelgar's clan. Unfortunately by the time you get it Khelgar is likely well on his way to becoming a Tyrran monk, meaning he relies on GoodOldFisticuffs instead of weapons, and the Hammer [[CripplingOverspecialization can thus only be reliably wielded by a dwarf player character]].
** ''Mask of the Betrayer'' has the longsword Sivlem, a weapon that has been attached to many glorious deeds. Its FlavorText has a weird {{Invoked|Trope}} DoubleSubversion when the mage enchanting it intended to give it [[TalkingWeapon an intelligence]] that would [[InvokedTrope drive its wielder to yet greater acts of heroism]], but applied said intelligence to a more mundane blade by mistake.
* The Daedric Artifacts (at least those that are weapons) are the most legendary weapons in ''Franchise/TheElderScrolls'' universe. Each is associated with a particular Daedric (daemonic, more or less) deity and passes from owner to owner according to the wishes of those deities. Famous ones include the hammer Volendrung, the dagger Mehrunes' Razor, the Mace of Molag Bal, the sword Dawnbreaker and the staff Wabbajack.
* ''VideoGame/TalesOfGraces'' has the sword of Asbel's father, Aston, which was a legendary eleth sword. When Asbel was in training as a knight, he sold the old, rusted sword for cheap to a traveling merchant called a "Turtlez" (one of many in the game), not realizing its history or potential. Much later in the game, the player can buy it back for hefty premium and take it to the Amarcian Enclave and it turns out to be the extremely powerful Excalibur.
* In the arcade ''DungeonsAndDragons'' games from Capcom, at the end of Shadow of Mystara, if a player kills the final boss with a magical sword (i.e. any sword that they did not start with), the epilogue states that the weapon is renamed "The Sword of (Player Name)". On subsequent playthroughs, the sword is ''actually called that'' for anyone that picks it up. At least, until the cabinet is reset.
