The Kama or Kai was a sickle used for harvesting crops and other farming purposes.
Techniques[]
The shinobi used kamas to cut through bamboo fences. These fences would have clay applied to them. The Bansenshukai shinobi manual contains a folding version. There are various traditions that detail the use of some form of lubrication that muffle the sound of a kama sawing through a hard material.
