Re: Love to hear your oppinions on this video.
I thought the purpose of the exercise was to practice the TARGET is holding a knife, but is unwilling to use it on his ATTACKERS; if that was the goal, well done. That being said, an atemi with a knife in your hand would create some spacing, I think.
My first instinct was to say "Get rid of that blade if you are not going to use it" but realised if you threw it away, guess who would pick it up and use it?
As long as the goal was to learn how you think you might react in a similar situation, with no dillusions of how it might actually play out, then I say have fun. And fun is never a waste of time.
