OK. Here we go.
Yes I very much doubt if they are exactly the same. I was merely commenting on your comment that "knife defenses against jabs, downward strikes, inside to outside, and outside to inside" are taught in your curriculum.
We also have defenses to downward strikes, inside to outside, outside to inside.
/end noted similarities.
Regarding "block / counterattack" it sounds like flawed technique to me. A deflected knife attack (i.e., a "blocked" attack) leaves the attacker free to initiate ANOTHER knife attack if your counterattack does not disable to the attacker and/or disarm the attacker. So if the attacker is NOT disabled or disarmed, what then? Rinse, repeat?
What are these wonderful techniques that enable you to block in such a way that "the knife is used to cut the attacker from top to bottom"? I find that sort of cut, if deep enough, to be exceptional with a blade that small Ā or superficial.
We do have some techniques in which we use both of our hands to redirect the point of the knife back into the attacker, but I am having problems visualizing this "top to bottom" cut. And this happens USUALLY? Not just some of the time? Outstanding.
In ALL hapkido? What makes you think so?
I am relieved that I am studying Moo Sul Kwan hapkido in which we assume the attacker is larger and stronger Ā and yes, maybe even faster and more accurate. Our thinking is smaller, weaker folk rarely attacker us. We certainly hope they are slower and less accurate but do not rely on those factors. The older I get the more people there are that are faster than me but turns out I don't end up "in his sphere of greatest power."
I guess I'm just lucky, eh?
