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 Twin Rising Dragons technique, while Jiga magnetises it with his Magnet Ninja Art 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
There are apparently different sizes of kusarigama as the one employed by Hanzō appeared to be about a metre long while the one used by Tenten (as well as the one used by one of the shinobi attacking Black Zetsu during the Fourth Shinobi World War) appeared to be about one-fourth that length.
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.
