What passes for "knife defense training" is so off the mark as to be useless. When the blade comes out, you will be lucky if your primitive reptile brain was smart enough to know you were playing around with bullshit and ignores all of it. The only worthwhile part of that grabbing the wrist knife fighting material is if you happen to do some pushups at the start of the class.
So you've tested this theory?
You're saying you are experienced in adrenal dump reaction time and response?
You have but from your opinions you have no idea that you have or how it was done.
So you have these big strong wrists, do you know how the physiology of the wrists and arms work?
How to lock up range of motion?
How is big strong wrists going to help you when a knife is being swung in your face?
I'm sure you've tested this right?
The whole point of training is to sharpen your reaction time and short circuit the flight response.
It's as if non of you have ever really thought or practiced the psychology of combat training whether it be sport or more operational based.
I'm not thinking about not getting my balanced broken or center compromised when I'm grip fighting in Randori, I've trained to make it unconscious.
It's as if you guys have never realized that process for combat sports came from actual combat training.
How many ex combat vets can subconsciously count expended rounds? It's not like their like "Ok...1...2...3..." on their fingers in a firefight.
There's a million other things like that, that are magically impossible to the sport combat crowd as soon as it becomes a not combat sport theater.
I know how to check for weapons before I pat down. It's so automatic out in public now any time I see anyone of a certain age group, physical capability and cloths choice, subconsciously I'm checking for concealed. It's "trained" into my skill set.
Not to say you don't need competent quality training, you do and theirs good weapons training available if you actually look for it.
So stupid!
