Shuriken (手裏剣; lit: "hand hidden blade") is a weapon of Japanese origin sometimes used for throwing. The art of throwing a shuriken is known as Shuriken-jutsu, and was thought as a supplement to other Koryu skills.

There are two main forms of Shurik the bo shuriken (棒手裏剣) a straight form of projectile, and the star or round shuriken.
