I think it's the best formula. Move away from the imminent while attacking, gain control over the knife arm, disarm.
Blocking only occurs when the attack is too sudden for you to get out of the way, usually in close quarters upwards or downwards stabbing, and with a surprise slash.
I'll have to see the level two Krav knife defenses before i pass judgement. Everything i've seen in Krav level one for knife defense Does. Not. Work. Ever. I've tried each of them with the people from my kali class and have expierienced a 100% failure rate. The straight inside blocks versus the high and low line are pretty damn ineffective, and the hip movement/footwork (from the "360 defense drill) is the exact opposite of what you want to do
For clarification-
360 defense drill defense against the low line thrust
- shoot hips as far back as possible, jamming forearm down to hit the incoming forearm perpindicular to the incoming force as hard as you can while maintaining a 90 degree bend to your arm.
Kali basic basic knife tapping defense against the same thrust
- arm wipes from high left to low right in circular motion, contacting along the forearm, moving the attack offline. Once off center mass left hand jams the elbow to stutter the return motion. At this same you sidestep, moving your hips off the line of attack in the other vector from the line of attack.
Notice these are both very basic defenses that take at most a minute or two to teach. The one i learned in krav utterly robs me of mobility, keeps me on the line of the attack such that any continued movement from the attack places the knife in my intestines, and doesn't end with any control of the attacker. Even if i incorparate a strike along with this technique i can't use rotation to generate any power, so my percentage of knockout or stun is exceedingly low.
By contrast, the footwork with the knife tapping defense is agnostic to my opponents reach or continued motion(actually if he cotinues the direction of the original attack it aids me), generates rotation for an angular attack on the spot, and leaves my feet in a position to exit in the window i just opened up outside of his weapon hand.
If there's better work in level two, i'd love to see it.
