Oh, I agree that his experience and understanding of the knife is poor based upon what he is doing. I don't want that to be misunderstood. In fact, I chastised him earlier about what he is doing being dangerous and I still believe that. However, my point still stands in that many FMA systems which are supposed to be knife-heavy (other FMA systems are not necessarily this way), tend to add and add more flashy techniques, even with the knife, in an effort to "keep up with the Jones's". In PTKGO, we look at the knife as a simpler weapon since: a) it cannot be manipulated the same way as a long weapon; b) it is often an ambush weapon that you don't see coming until the last moment, if at all; and, c) it happens at extremely close range giving you less time to react/counter.
