I have been deep in meditation on the problems that knife work. I have been sorely disappointed with the kata work of judo and aikido. It does not mean that the answers for the aiki of knife work are not out there, they just might come from a different school of thinking. I bumped into this video on my search, and I think this guy would probably best me in a knife engagement.
