Hello everyone
Again it seems my internet connection is very slow and rare today because it's the second time I wrote a reply and I lost it

I'm almost crazy.. but I will try to reconstruct my post...
My idea in the truth about knives is "there is NOT true about knives" because every single case is different, and every situation is different too... that's why this is a very common topic in EVERY martial art or selfprotection forum on internet.
Of course there're some basics principles and point about knife attacks and situations, one of the best rules I ever read is "knifes cut flesh, ALWAYS" and you must put in mind when training against a blade.
In my opinion there're some common scenarios, such as:
* Knife against knife: This is a very rare scenario but not uncommon, here the FMA practitioners have advantage
* Knife against another weapons: More common and usual if you use improvised weapons (one of the best defenses against knifes). Here enter knife vs sticks, chairs, ashtrays, etc
* Knife against hands: The most common (although you're a knife user) and most studied on martial arts, unfortunately from a wrong point of view almost all the time...
If you remember the rule I mentioned before, the training progression must be from knife - improvised weapon - hand and not the opposite (like many traditional martial arts) because you ALWAYS can obtain an improvised weapon and it's preferred to use it than hands (W.E. Fairbarns, the father of WWII Combatives once said "there's not defense against a knife"
If you train the third situation also there're simple rules in order to survive, but the main idea is: you SURVIVE against a knife attack, you don’t WIN; and one have to put that mindset in the training, it’s a survival game, not a fighting game…
The general concepts I use are:
• Move out from the line of attack: This is easier to say than to do but… you always must to follow it
• Control the weapon hand/arm: Or “delivery system” as some people named, this is the more difficult thing but not impossible.
• Finish the threat: Via breaking the arm/wrist; striking the guy, etc
• Go away… and very fast: This is the difference between self protection and assassination
Of course, there’re MANY ideas about how to accomplish the concepts, I prefer to strike every time I have a chance, and to control the head/spine of the attacker, but some other people have another ideas…
Also, as mule posted, there’re some myths regarding knife wounds/stabs that aren’t true, like the “one stab one death” “train to get cut” etc; the main thing here is “you MUST train as real as you can” because the 99% of the TMA techniques DON’T WORK against a real street attack because they’re “dojo techniques” that’s they only work on a controlled environment like the dojo and against a compliant partner…
Again my 5 cents on a topic, excuse my English and my internet connection… take care to all
