Kusarigama

A kusarigama (Japanese: 鎖鎌, lit. "chain-sickle") is a traditional Japanese weapon that consists of a kama (the Japanese equivalent of a sickle or billhook) on a kusari-fundo – a type of metal chain (kusari) with a heavy iron weight (fundo) at the end. The kusarigama is said to have been developed during the Muromachi period. The art of handling the kusarigama is called kusarigamajutsu.
