A superb article from Marc MacYoung on the lies of knife fighting:
“The only place where the knife fighting fantasy exists is in the martial arts. There is no such thing in the modern civilized world. In legal terms it is attempted murder, assault with a deadly weapon or homicide. To the streetfighter it is assassination, not a "fight" at all. To the criminal it is a tool for robbery. Everyone else considers it abhorrent macho stupidity.
…The myth of grappling is that it works everywhere. The fact that it proved so successful in the UFC ring has blinded many people to the fact that there are critical differences between fighting barehanded and fighting with weapons. While empty-hand fighting might easily turn into an endurance marathon, where size, strength, physical shape and ability to endure punishment significantly influence the outcome of an altercation, that is not applicable to weapons work. In that arena, every man bleeds the same.
… Do not attempt to "grapple" with a knifer. Once on the ground, you are not guaranteed to be able to control his knife arm well enough to prevent him from carving you up. If it were a barehanded fight, then you can often prevent him from being able to generate enough power to effectively strike you, but a knife doesn't need power, it just needs to touch you. And if you are attempting to control his arm while on the ground, he will wiggle free and repeatedly cut you until you can no longer continue to resist.”
