TJS, I practiced and taught a system similar to KM, that included gun, stick, and knife defense, etc., for several years. I thought all of the techniques would work, and had tried them against larger and stronger people, after telling them to resist, etc. I later found out that they would not. Most people who are friends with you, or are practicing the same style, will have a hard time resisting like some lunatic on the street would. I think it is most important for anyone practicing martial arts, to try to find a week point in each defense or method. This is most important with regard to weapons defense, since one mistake can get you killed. As I said, I have tried many of the KM gun, stick, and knife defenses, and none have worked against a fully resisting opponent. Now, that is not to say that they will never work, or that they might work if you have the element of surprise on your side. But, I am certain that they can be improved upon. Take the gun strip I mentioned before for example...the strip occurs on the second beat, after moving offline. If you tell your partner to try to yank his arm back and away as soon as you begin your defense, you will see that he will be able to. I think an attacker on the street would certainly try to jerk out of your grip immidiately also. With regard to the knife defenses, give your partner a marker, put on an old T-shirt, and tell him to try to slice you up as best he can, and try the knife defenses. The last point I will mention, is that any style that is made up of a number of specific defenses against specific attacks, is practicing for the first instant of an attack. If your initial defense fails, of course it may not, what is the backup plan. I'm not trying to blast KM here. I think it's more effective for self-defense than the majority of what's out there. Just make sure you test everything you do, before trying to use it on the street. Good luck, David https://www.hertao.com
