When we spar in my dojo, we basically do it in two ways. I come up with non-scripted kata based interactions for students to try out bunkai and I try to make sure that my students are familiar with the rules of various combat sports. Recently, I covered point sparring with my students and we did a bunch of drills to make sure that would could throw our techniques with control. I explained that we were learning point sparring because I felt that it would help them see openings in people's defense and that they would learn how to put a weapon in that opening. Does that sound valid to you? Can we find any value in non-contact sparring, or is this one combat sport that is just too different from reality to even bother with?
