- "They say that Biggoron's Sword is super sharp and will never break."
- — Gossip Stone
Biggoron's Sword (ダイゴロン刀 Daigoron Tō?) is a recurring sword in the Legend of Zelda series. A large two-handed sword forged by Biggoron, this powerful sword cannot be used in conjunction with a shield.
Biggoron's Sword is the strongest sword in the game, dealing twice the damage of the Master Sword. As a tradeoff, it cannot be used in conjunction with a shield, as Link must use both hands to wield it. Identical to the Giant's Knife in all respects except durability, Biggoron's Sword does not break after any number of hits. When sheathed, it has the exact same size, hilt, and sheathe as the Master Sword, even though Biggoron's Sword is extremely different in all three of these aspects. This was fixed in the 3DS re-release of the game.
The game states several times that Biggoron's Sword cannot break; however, during the quest to obtain it, Link obtains an item called the Broken Goron's Sword, which is apparently a broken version of Biggoron's Sword, though it may be considered a different sword which only becomes truly unbreakable after being reforged.
To acquire the sword, Link has to complete a fairly long and complicated trading quest with multiple stages, some of which are timed. Biggoron, the sword's creator, is found at the apex of Death Mountain when Link is an adult. After Link hands him the eye drops, Biggoron will begin forging the sword. This takes three days, though the wait can be shortened with the aid of the "Sun's Song". Biggoron's Sword can be used in the battles against Ganondorf and Ganon, but it cannot deliver the finishing blow as it does not have the "power to repel evil" that the Master Sword has.
Biggoron's Sword is the strongest sword, and it has a longer reach than the other swords. However, due to the fact that it uses both of Link's item slots, other swords may be preferable; using Biggoron's Sword will render him helpless against enemies or bosses that require a sword used with another item to defeat.
In an Oracle of Ages Linked Game, Link can learn Biggoron's Secret from a lone Goron on Rolling Ridge in the Present. The secret can be relayed to Biggoron on Goron Mountain in Oracle of Seasons. Biggoron will reward Link with Biggoron's Sword, which can be taken back to Labrynna using a secret.
In an Oracle of Seasons Linked Game, Link can learn the Elder Secret from the Red Goron in the cave below Biggoron on Goron Mountain. The secret can be relayed to the Goron Elder found at the Goron Gallery game on Rolling Ridge of the Past in Oracle of Ages. After earning enough points in a Goron Gallery game using Biggoron's Sword, Link will be rewarded with said sword, which can be taken back to Holodrum with a secret.

- — In-game description
In Breath of the Wild, the Biggoron Sword can be obtained by Link via using the amiibo Rune with the Link amiibo of The Legend of Zelda: 30th Anniversary series, to complete the Hero of Time set. Like in past titles it is depicted a two-handed sword, however it is no longer unbreakable. It has a base attack rating of 50 and like in Ocarina of Time is stronger than the Master Sword in terms of attack power and durability. Its size prevents Link from using a shield and lacks the Master Sword's unbreakability and ability to fire Sword Beams. Its description reveals that it is a greatsword that has obtained legendary status.
Unlike the "Hero of Time" armor set pieces, the Biggoron Sword will only start to appear after Link has completed and freed one of the Divine Beasts, thus will not randomly spawn until Link has completed at least one of the Divine Beast dungeons.
Biggoron's Sword is a weapon in Link's arsenal. It can be bought in Chapters 8 and 10 for 4000 gold. He wields it with one hand, with his shield in the other, yet in Ocarina of Time, Link wields it as a two-handed weapon (however this was likely done to fit Link's sword & shield-based fighting style in the game). It has a much longer reach than Link's other weapons and a higher attack than most, but it drains health slightly with each slash because of its weight.
Biggoron's Sword appears as Impa's third level weapon of her Giant Blade moveset. It has a single edged curved blade, as opposed to a double edged spear pointed blade. It also has a larger sheath. Like all of Impa's Giant Blades, it has a water elemental attribute.
