Wooden Sword

In The Legend of Zelda, the Wooden Sword is found at the starting point in the cave. Link uses this sword until he obtains the White Sword, which is more powerful.

This sword is also first weapon obtained in the Oracle games.

The Sword is also in The Legend of Zelda: Twilight Princess, being the first sword he receives. He receives it from Rusl as a present, and it is with this sword the player learns basic sword fighting skills. Link keeps this sword until after he rescues Talo. He eventually gives the sword to Talo so he and Colin can get past them to where Ilia is holding Epona.

Later on, Link comes across the broken wooden sword when he is looking for the children as a wolf. From these pieces he is able to pick up the smell of the children.
