The fūma shuriken is a large, four-bladed shuriken possessing pre-eminent sharpness and lethality. This type of shuriken is considered characteristic to the famous Fūma clan, after whom they were named and who possibly developed them. However, their use is not limited to this clan. Its four blades can be collapsed for easy storage, leading to its nickname Shadow Windmill (影風車, Kage Fūsha).
As Zabuza Momochi and Obito Uchiha demonstrated, the shuriken can be used in melee combat, by spinning the blade in one's hand to slash and stab the opponent directly. In Sasuke's battle with Itachi, he has shown the ability to rig the four blades to disconnect via pulling a connected wire and have them fire in cardinal directions as a surprise attack, as well as imbuing it with a Chidori to increase its cutting power.
