If you are looking for a video clip, let me explain why I would never put a clip of myself doing this.
And you might want to go over to Amazon.com and look up my review of the book knife fighting in Folsom prison. You will clearly see that I talk about reading it and practicing against the types of things that people in prison are learning- rather than any type of sport attack. I posted that a few years ago after going over it with some friends in America that had some good pads.
I searched for Folsom prison on amazon and didn't turn up much. Do you have a link?
So no trying to hint that I have never done anything like this and are scared to try it, ok?
I rarely speculate about the motivations of individuals. I'm not sure what "like this" would refer to.
When you train in forms and such, you try to make your movements as perfect as possible. There is a reason why a good teacher will correct you to the exact angle your legs and knees should be in.
The same thing I was told in karate. Ok.
But Peytonn Quinn (no stranger to violence) has put it best when he said that real combat (or anything close) is going to be messier than training. And if you train messy, then you will have nothing in a real fight.
No arguement there.
So, if I were to tape the sessions I had going against a guy using the prison techniques, they would be of fairly messy taijutsu. They would not reflect the training I do outside of that. And it would not be obvious that I only had what level skill I did in the clips because I had other training that was done to a higher level of expectation.
I think you will find that many people are more than willing to look past messy appearance if it is effective. Heck, if you watch MMA legends like Igor Vovchanchyn or Fedor they appear quite sloppy on first look, but they seem to keep winning fights. I don't think we will judge your level of skill by the appearance of techniques etc. so much as the level of resistance and competency the opponent shows.
The clip would not be something that I would want others to hold up as an example to copy and learn from. All it would serve is to somehow prove something to others. And quite simply, I really do not care enough about what those people might think to go to the trouble. It does not seem to be worth the effort, let alone the fear that others might think that the mistakes I know will crop up are something to be emulated, to satisfy the curiosity of others about my abilities.
If I were to put up clips (don't hold your breath) it would be of something that I would not be scared of others copying as best they can and looking for lessons on how to do things. At this point, even that does not appeal to me.
Without knowing the training behind it, it is hard to emulate more the the appearance of a technique. This is true of all arts that I know of. I doubt very much if anyone would be able to steal your techniques or skills based only on a clip of them in application.
