sorry, i really have to say it is ridiculous how you all defend against the reality that traditional styles won't prepare of real knife attacks. if ever a style could do so. even with speed and grip strenght. sure one should first train it like that to get the basics of blocking and wrist locking. but anyway. find a suicidal aikido-guy who trains this all the time, dress him like an israeli and put him to the gaza strip. you'd see what happens. at 2:18 its exaclty what i mean. if you tell me, with traditional knife defense training you could defend it, you're lying to yourself. and now "dislike" my comment, like many people do with unpleasent truth.
