on looking at many of the names given to the movements in Kata and forms, they seem larely to supportt the block,kick,punch method. I would see this becasue many of the are name as a either a block, a punch, or a strike.
If we take a large step back to the chinese styles, the names give to the movements were very obscure maybe to hide the application from others. you get names like "snake creeps down" or "white ape offers the peach" to describe movements. that are throws or stirkes. very often the application of the movement is not clear from the name. apart from very few execeptions
so the names have eveolved somewhat over the years. Was there ever a time in Karartes hoistory that the names of the movements were not what we know that as today, and didn't support the block,kick,punch method
