Woof All: As I discuss in the vid-clip "Knife Ruminations" on our website, I have a certain reluctance to teach offensive knife openly. I'm not sure this makes sense in a world of guns, but it seems to me that training offensive knife calls to the darkness is a special way. The Die Less Often material is ANTI-knife and is intended to give the best odds possible against the most like kind of attack in the American environment: Crazed forehanded thrusting (and slashing) either untrained or trained, as in the Prison Sewing Machine variations. My thought here is that the bad guys already know these things, and that I help the cause of the good to help good people acquire a more realistic sense of what they might really face. This is an example of the DBMA teaching principle "Teach Primal Probabilities First". In that context of course there needs to be a block of material to respond to the Ice Pick Caveman based attacks. I have had a couple of random techniques that I like, but frankly the material was not up to the standard that I think I achieved with the anti PSM material. While part of the challenge was to maintain the "Consistency across categories" concept so as to minimize reaction time, the simple fact was that I did not have a matrix and grid the way I do with the anti-PSM material , , , until today. Of course the material will need to be pressure tested further, but two seasoned students and I aired things out fairly well today and my doggy nose tells me that today was a moment of satori. The Adventure continues! Guro Crafty PS: This past Friday I had a very intriguing day being trained in the very interesting Piper Knife system of South Africa. One of the moves that I learned on Friday appears in the new anti-Ice Pick Caveman material.
