Kokiri Sword

The Kokiri Sword is a small sword used by Link as a child in The Legend of Zelda: Ocarina of Time. It does not return in the direct follow-up, The Legend of Zelda: Majora's Mask, where it is replaced by a generic sword instead.

The Legend of Zelda: Ocarina of Time
The Kokiri Sword first appears in The Legend of Zelda: Ocarina of Time. At the start of the game, Mido does not allow Link to meet The Great Deku Tree unless he is equipped with a sword and a shield. Link can obtain the Kokiri Sword in the Hole of Z (named "Hole of L" in later releases). At the end of its maze, there is a Treasure Chest containing the Kokiri Sword. According to the text from obtaining the Kokiri Sword, it is a hidden treasure of the Kokiri that Link is borrowing.

Link cannot use the Kokiri Sword as an adult, and if Link steps through the Door of Time with the Kokiri Sword equipped, it is replaced with the Master Sword when Link becomes an adult.

Super Smash Bros. series
In Super Smash Bros. Melee and Super Smash Bros. Ultimate, Young Link wields the Kokiri Sword as his primary weapon.
