Darknut Swords are swords from The Legend of Zelda: The Wind Waker. Wielded by Darknuts and Mighty Darknuts, they are some of the most powerful weapons in the game; in fact, until the Master Sword has its power fully restored, they are the strongest weapons Link can use. Darknut Swords are powerful enough to knock down pillars in certain rooms to reveal hearts, arrows, Rupees, or other items. Link can acquire a Darknut Sword by counterattacking a Darknut and causing it to drop its sword, or by defeating the Darknut.
Darknut Swords cannot be carried between rooms as they are not available for use from the inventory screen. They can be thrown to damage enemies at long distances; however, due to the weight of the swords, they do not fly very far, and take a little longer to swing than most other weapons.
