You guys are scarin' the crap outta me, I want my momma!!!
It is true that few people know more about the realities of an edged weapon attack that corrections officers and inmates. Basically what I teach CO's is this. They are gonna have a weapon and you are not. You are likely to feel the attack before seeing it. Trap, isolate the offending arm and do your best to smash their head into the floor, wall, and bars. Stop when they are not moving anymore. Deadly force is deadly force.- George
I've had a knife pulled on me once, but he was a complete idiot and I simply kicked it out of his hand before he could do anything with it. Think of the movie cliche of, "Ha ha! Who's a tough guy now, *insert random dis here*?" quickly followed by getting schooled by his opponent. It was so sad that my adrenaline didn't even fire up during the incident.
I have no issue at all believing your anecdote about your knife wounds. That sort of stuff happens with gunshots, even from the much vaunted .45 ACP, all of the time.
When forced to retreat, people will resort to slashing irregardless of their training for the instinctive reactions mentioned above. Stabbing while retreating is an exercise in futility. However, that is largely a training issue, IMO, rather than a lack of stabbing being an effective tool.
Typical knife force on force scenarios, if mercop's excellent training example videos are any indicator, start with the defender backpedalling from an armed or unarmed assailant while attempting to ready their weapon and it goes from there. Good to go. However, I don't typically see the defender passing a slash or thrust and JUMPING ON THAT MOTHER-BLANKER, TAKING HIM DOWN AS YOU STAB HIS NECK, DOING A DOUBLE KNEE DROP ONTO HIS HEAD AND FLOATERS WHILE PINNING HIS ARM TO HIS SIDE AS YOU MACHINEGUN YOUR KNIFE INTO HIS ARMPIT/HUMERAL ARTERY AREA AND NECK WHILE DELIBERATELY DOING EVERYTHING YOU CAN TO KEEP HIM FROM FIGHTING BACK.
I kind of think this sounds legit
