I have survived two knife attacks when I was younger. One I was lucky and the jerk was waving it around trying to impress his friends. For a second he looked at his friends and smiled. Bad move on his part. It was probably more of a threat display than anything else. I could not run away because of where I was at. Second was more like the video.
Guy came running at me from behind. I heard him and turned. All I could do was jump back a bit. Knife went in below my belly button. Because I pulled back it didn't go in deep that's all that saved me. Right away I went on the offense. Still have a nice scar from them sewing me up. Had I not heard him I wouldn't be here. I am amazed by all the b.s. you see some instructors teaching their students. Or on some video's.
Most of the "knife defense" training where the guy steps out and politely holds is knife hand out for you and the lock it, arm bar you, or whatever is b.s.. Like the knife instructor in the video pointed out if someone is going to stab you they are going to try to get close. They will hide the blade. And when your attacked it will be a wild frenzy of multiple stabs and slashes. As someone wise once pointed out "most knife attacks are knife assassinations". And the attack set ups in a lot of Dojo's , or Dojang's the person only attacks with the knife. No in reality they are probably going to be grabbing you with the other arm, hitting with it, kicking, whatever.
You are going to have to probably start with empty hands. Don't just stand there. Get off the x. Get something between you and them. Pick up anything you can as a weapon. A knife attacks is a deadly force situation. Up close a knife is I would dare say equal to a gun. Simple test. Put on some gear to protect yourself. Give someone a red magic marker and tell them to really go at you. You may "get them". But you will probably find yourself covered in multiple red dots and slashes. All I am saying is the famous "you brought a knife to a gunfight" isn't what it seems. A knife is not a ballistic weapon like a club. It only takes a short flick or jab to put you in a whole lot of hurt.
Best thing to do is be aware of what's going on around you. If you can see it you can probably stop it. If it's a sneak attack it is really hard to defend. Your starting way behind the OODA loop. Get off the x as fast as you can while drawing your gun. If you can get something between you. Most people stabbed unless it is in somewhere like the eye don't know know they've been stabbed. The think they've been punched. Stay alert, watch the hands, don't let them get too close. Keep a gap if you can. Distance is safety. And God help you if you really have to go at it with a bladed opponent. Few things prepare you for the speed and the viciousness of such an attack. Get some gear, a blue gun (or airsoft), and a plastic knife, with a partner. At best you'll survive a percentage of times. The more you train the better you percentages. But know how difficult it is to really defend against a blade. Once on top of you a blade is at least the equal of a gun. And as someone said. Unless you get a good head shot in. They might just keep doing what they were doing before you shot them. At least for awhile. Not good.
