Jiu Jitsu teaches pressure points, throws, holds, and a little kicking and hitting. Google it and you should find some books on the topic. I did use it a little when I was kid, but never had to really mess anybody up. Lock up there wrist, push on a pressure point, and if you're a skinny kid doing it, well there's that "surprise" factor I spoke about earlier. They were quick to back off.:D
