The Kusari-gama is a combination of a sickle (short scythe) and a long chain with a weight attached to the end of it. The sickle was used in a slashing or stabbing motion, as well as used to block and hook opponents weapons. By holding the chain portion of the weapon, the sickle could be swung around to get a greater reach with it.
The chain portion of the Kusari-gama was most often used for trapping an enemy or his weapon. Once tangled up with the chain, the ninja could finish him off with the sickle. This was a weapon the ninja invented out of farming tools they used.
