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.
