Kusarigama


The kusarigama is a traditional Japanese weapon that consists of a kama on a kusari-fundo – a type of metal chain with a heavy iron weight at the end. The kusarigama is said to have developed during the Muromachi period.
The art of handling the kusarigama is called kusarigamajutsu.

Methods of use

Attacking with the weapon usually entailed swinging the weighted chain in a large circle over one's head, and then whipping it forward to entangle an opponent's spear, sword, or other weapon, or immobilizing his arms or legs. This allows the kusarigama user to easily rush forward and strike with the sickle. Also, the weapon is said to have the highest mortality rate of any and all weapons of its time.
A kusarigama wielder might also strike with the spinning weighted end of the chain directly while still outside the range of an opponent's hand weapon.

Legality

In the Republic of Ireland, the kusari gama is classified as an illegal offensive weapon.
In Canada, under the Criminal Code of Canada's centrifugal force criteria, the kusarigama is a prohibited weapon due to the chain using said force. A kama is legal.
