Kusarigama

A kusarigama is a traditional Japanese weapon. It contains a sickle attached to a chain. It may be used to attack opponents, or to incapacitate them with the chain. Some skilled kusarigama users can even steal their opponents' weapons. Tenten used it as a projectile in her technique, while Jiga magnetises it with his  to steal opponents' weapons. Hanzō is noted to be a very skilled user of the kusarigama, which he has drenched in poison to further increase its lethality. Unusually, he tended to deliver strikes by swinging the sickle with the chain, rather than simply employing the weighted end, which is generally considered to be the most effective manner.

Types of Kusarigama

 * An unnamed Konohagakure shinobi used an unusual one against Pain's Deva Path in the manga, as this one was fully compactable so that it could easily be carried about his person. Both the weapon's blade and handle were collapsible, with each comprising from two and three individual sections respectively. However, in the anime, this weapon was instead replaced by a similarly compactable kama.
 * Hidan's Triple-Bladed Scythe has a long metal cable attached to it, and the way he uses it is similar to a kusarigama.

Trivia

 * Curiously, though traditionally ninja weapons, in the weapons arsenal of the samurai of the Land of Iron, kusarigama were seen hanging on a wall.
