The title pretty much gets at my interest. I currently study PTK, and am very happy with the system. In the past I have trained a small amount of Sayoc as well as getting into a bit more of Lacoste-Inosanto, and Modern Arnis before that. Sayoc is obviously known for knife, and Lacoste-Inosanto has a strong knife curriculum as well. Modern Arnis focuses mostly on solo baston and not nearly as much on the knife and in my experience with the system, the knife material was rudimentary at best. That is fine, no judgement is being made. Different systems focus on different things, and that is OK. Obviously, one of the things that FMA is known for is its knife training as well as knife defense. That got me to wondering what other FMA systems out there have a particularly solid and realistic knife curriculum that I might be unaware of. For any number of reasons, in my humble opinion, PTK's knife work is the best I have seen (to date) in terms of its functionality and realism. But, that doesn't mean there are not other groups out there doing good things. I'm not one of those guys who thinks that the sun rises and sets with PTK, and I really see us as more of an FMA brotherhood than competing between systems. One of the other systems I am really interested in seeing is the Tulisan Knife System from Bakbakan Kali Illustrisimo. From what little I have seen and heard, it sounds like something that would be solid, but it is hard to find info out there on it. I have seen other FMA systems that focus on the knife a good deal, but without naming names, what I see seems so flowery and subtle with its focus on disarms and trying to slash while passing, that I am doubtful as to its real world effectiveness and being able to pull it off against a resisting opponent. In the interest of fairness, there are some within PTK who have embraced this sort of thing as well. My interest in knife work is simple. It is the thing that is easy for me to carry on a daily basis. So, how about it? What else is out there that I have not seen that is good/functional/realistic when it comes to knife? Videos, if available, would be good to see as well. I look forward to the discussion.
