The Iron Bow is an item from The Legend of Zelda: Skyward Sword. It is the upgrade to the bow, and can be further upgraded to the Sacred Bow. The Iron Bow is more effective and accurate than the regular bow. Like the regular bow, it can fire spiraling drill like arrows when charged for increased damage.
The Iron Bow can be upgraded at the Scrap Shop in the Bazaar from the bow by using three Tumbleweeds, one Evil Crystal, three Monster Claws, and two Eldin Ores.
