Practice Sword

The Practice Sword is the first Sword Link obtains in SS undefined, given to him by Eagus.

Location and Uses
After Groose, Cawlin and Strich steal Link's Crimson Loftwing, Link needs a Sword to get it back. He goes to Eagus in the Knight Academy's Sparring Hall for a Sword and Eagus gladly allows him to train with the Practice Sword. Link will then attempt to leave with the Practice Sword only to be scolded by Eagus because taking Swords outside of the Sparring Hall is not permitted. However, upon hearing that his Loftwing is missing, Eagus makes an exception and allows Link to use the Sword on the condition that he completes some training exercises in the Sparring Hall. To find his Loftwing, Link needs the Practice Sword so that he can cut the wooden spikes guarding the Waterfall Cave and go through it. After his Loftwing is rescued, Link keeps the Sword until he is introduced to Fi within the Statue of the Goddess and receives the Goddess Sword.

Trivia

 * The Practice Sword is the least effective Sword of the Zelda series. It takes two hits to down a Keese, one of the game's weakest enemies.
