And that's why you don't wait to find out how much skill the blade guy has ...
If confronted with a knife .... shoot as fast as you can.
The American martial art .. “way of the gun” can be an effective defense ... but only if your ready, fast, willing to take a hit and do the deed.
One of the worst attacks is a trained blade guy with a real goal.
Situational awareness is key .. and really the only defense. (you must be a blade guy)
Lol, no I’m not a blade guy, I just know enough to be able to do realistic knife attacks when training in knife defences. I usually get my man regardless of skill level before I get taken down. When Im defending against a knife attack (and I have done a lot of that over nearly 20 years), even when Im successful my arms get “cut” and I take at least a couple of stabs before I get control. On those rare occasions when I am totally successful it’s because my partner is inexperienced and is really telegraphing the attack.
Im not going to say knife defences are useless against a semi-competent knifeman, but at most they raise your odds of not getting seriously injured or killed from 0% to almost 0%. If someone knows pencack silat or kali etc and you dont have a gun drawn out ready to shoot within 20 feet or are not able to run away. Make your peace with God because you are Donald Ducked.
