For combat purposes it sometimes took the upgraded from ofa Kama-Yari, a spear with a hooked blade, and it is related to the Kusari-gama, a sickle attached to a weighted length of fine chain. he weapon was used either singly or in pairs entirely for close work where it could slash, hook, rake, chop, deflect, or block in a wide range of basic combination tactics.
