In Okinawa, where there was a strict prohibition against weapons, the Kama was a readily available tool that could easily be substituted as a weapon. Kata were devised but just a few practitioners trained with Kama, thus the number of Kata passed down was limited. The Ryukyu Kobudo Shimbukan teaches Kanegawa no Nicho Gama which is required for the 4th Dan grading.
Techniques (Waza) include blocking, stabbing, striking and cutting. Normally only senior practitioners perform Kama Kata. The kama are sometimes called Kusarikama.
