Kusari-gama is a traditional Japanese weapon that consists of kama ( the Japanese equivalent of a sickle) on a metal chain with a heavy iron weight at the end. Though the kusari-gama is derived from a farmer's sickle, and though the sickle was often carried as a weapon by farmers during the feudal era of Japan, it is important to note that these farmers did not carry kusari-gama. Its purpose as a weapon was very obvious, so unlike a sickle, it could not be carried openly.
