Kama
The Kama is a Japanese farming implement, not dissimilar to a sickle, used for cutting crops. Samurai and various other martial artists have also made use of the Kama as a lethal weapon.
When used for farming, Kama will be used single handed (they come in right or left handed varieties) while the other hand holds the crops to be cut. Used as a weapon, Kama are invariably used as a pair.
Kama have a razor sharp tip and inner blade for their offence, but Kama can also be used as defensive weapons to block and disarm an attacker.
Like other lethal weapons, a great deal of skill is required to make effective use of Kama. Numerous martial arts still use Kama training to this day. As Kama training is difficult, normally blunt, wooden or rubber Kama are employed, which are much more forgiving than would be razor sharp Kama if a mistake was made.
Kama were extra effective as samurai weapons because of the confusion caused by having to watch, dodge and break the defence of two weapons being used at the same time.
Ever inventive, the Japanese created an even more complex and interesting weapon to overcome their enemy using the Kama as a basis, which became known as the Kusarigama.
