I'm curious, of all the "exotic" hand weapons such as the ones above used in karate, kung fu, kenpo, etc. how many of you can actually pull them off in sparring? How frequently do you manage to hit someone with something other than a closed fist? Personally, the only thing I could ever pull off is the ridge hand of the left. Typically, I would fake in with a backfist, and then kind of loop it around and hit the ridge hand. I don't think it hit very hard, but I seemed to be good at sneaking it on people. Especially other karateka.
