I got to do some of this with Mike Snow today. We haven't gotten together for a while due to my traveling out of town for 10 months for work. We played with the knife with the blade in reverse position (blade facing the arm rather than out). Of course, since we haven't seen one another for a while, we also chatted more than we should have! With luck, the Grandmaster will be back in Indiana for a visit soon. There's a lot of interesting stuff in this detailed system. It's heavily blade-oriented, which sometimes necessitates a change of mindset for a stick-centered person like me.
