It's kind of interesting that so many people think a thrown jacket is so useful in self defense. Against a punch or kick is one thing, but priorities change drastically when a weapon is in the equation.
Now if we were talking about a jacket like the one my friend wears that would be a different story. But he rides a motorcycle so his jacket has steel and carbon fiber plates inside it. Makes decent armor and is heavy and hard enough to knock someone silly or used to hit the weapon hand. Soft jackets just really aren't that useful.
That being said, I believe my part in this debate is pretty well over. My point stands that experiencing attacks firsthand is much better than all the advice in the world. And I don't expect anyone in the world to take my advice, or anyone else's at face value for that matter.
The point of training with a marker in place of a knife ( which I agree with Chris, I think the point was missed ) is that, unlike the training knives, it leaves a mark without damage. After a defense is executed you can look to see any contact with the "blade" and gauge the injuries you would have incured. The results will likely surprise you, I know it did me.
It was good advice to do this though, because it was a wake up call without actual damage. I was glad I trained in this manner because it allowed me to figure out good defenses and also to not get overconfident in my ability. And before doing this exercise I admit that I was WAY too sure in my abilities. The first time I tried this training exercise with a marker, I was covered in graffiti.
I could only imagine what might have happened if I had encountered an actual blade back then. And in all honesty, it probably would have been very bad for me.
Great points...no pun intended. I may've mention the jacket in some of my posts, but I do know that earlier, I mentioned something that would be a bit more effective. If I had a choice between tossing a jacket or a heavier object, I'd of course pick the latter. As for the more realistic training, ie: no lie blade, marker, I agree...those are great training tools, and if one is serious about SD with a knife, then this is necessary.
