Kama

A kama is a Japanese sickle used as a weapon. It has a short handle and a pointed beak with a sharp cutting edge that inflicts damage. There is also a variation of the kama, a kusarigama, which has a chain attached to it for increasing its attack range.

Unlike its traditional intended use, the kama has been most commonly observed being employed by shinobi as a throwing weapon rather than in close combat, where the entire weapon is tossed in such a manner that it rotates quickly end over end, to increase the probability that the bladed edge while strike its intended target.

Types of Kama

 * An unnamed Konoha shinobi used an unusual one against Pain's Deva Path in the anime, 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 manga, this weapon was instead depicted as a similarly compactable kusarigama.
 * The puppet that Fū used during his Mind Puppet Switch Cursed Seal Technique was unusual in that it featured kama in place of each of its upper limbs, where as its lower appendages were instead formed from hoes.

Trivia

 * Traditional use: Kama was used in Asia to cut crops, mostly rice. However it found its way into martial art where it was usually used in pairs. Since the beak usually was razor-sharp, it was a lethal weapon. It has been suggested that a skilled user could block, trap and disarm enemy weapons.
