Does shotokan kata incorporate weapons applications?
jitte or jutte your suppose to be able to use with a bo chinte there is also a weapon called chinte, which are bamboo sleeves that would wrap around the arm, i dont think this is any coincidence. chizakun, jiffa, hoko, techu and tekko as well as many other small less know weapons could easy be used with almost any empty hand kata Okinawan taught and passed on there techniques through kata. and considering there are over 40 weapons with only a small hand full having traditional kata the only other alternative is they used them with karate kata as for the the heian nidan making more sense to you with a weapon, it make a lot more sense as a grappling kata, there is no back kick in heian nidan its a side kick the opening move can be anything from a simple pushing of your opponents 2 arms who is coming in for a push or grab, to locking up his arms and redirecting him bring him down to the floor. kobudo is a far older art then karate, kobudo came first and dates back much further then karate
