Shuriken

A shuriken (手裏剣), like kunai, is one of the more basic weapons seen in Naruto. They are sharpened, four-pronged metal stars, useful for throwing. Although small, they can be used to distract, or, if accurate enough, can be deadly. They have an open circle in the center, used for grabbing with a finger, to avoid cutting oneself, or to put thread through. The circle is also a benefit in aerodynamics, as it ensures more accurate trajectories.

In addition to the basic shuriken, larger, arm-length shuriken have been seen in the series. They are usually carried on the back. The Fūma Shuriken is of a similar size, but is more lethal and can be folded together for easier storage. Shuriken can be increased in number by using Shuriken Shadow Clone Technique.

For example, Tenten is said to be extremely accurate at throwing shuriken - mentioned during the Chuunin Exam preliminary matches as hitting 100 out of 100 targets.
