I saw many interesting replies to this question - I am a 5th degree black belt in Okinawan Kenpo Karate Kobudo which is to mean that I study two entirely different art forms - karate - which is your open hand and Kobudo which is your weapons training - in a traditional federation/dojo you attain rank in both categories - there are 5 basic weapons in traditional okinawan weaponry - bo,sai,tunfa,nunchaku,kama and additional weapons Eiku Bo, Nunte Bo, Timbe/Rochin, Tekkos
