Re: knife defenses
In a Saturday pub scuffle I watched as a friend of my fathers (3rd dan in Aiki-Jutsu) was attacked by a drunken idiot holding a small switch blade. The attacker didn't perform Dojo friendly thrusts and swipes, but did quickly stagger over and wave the blade quite quickly (for someone drunk), and proceeded to cut off my fathers friends index finger and blind his left eye. With all his experience he couldn't defend himself against an attacker who doesn't even know where his own hands are, let alone act in a logical manner. This kind of attack is undefendible as you cannot predict where that blade is going to be next, in your ribs or in the attackers own leg. There is no defense other than running away.
