Pure Krav Maga: Under Hold Knife Defense/ by Boaz Aviram

Some Civilian Krav Maga organizations are forgetting that a real knife is not a rubber toy. The block an Underhold circular Knife Stab with the mirror forearm and continue to loop the attacker's hand with the same arm to prevent repeated stabbing attempts. 

Luckily for them it is a rubber or wooden knife, and their attacker is their training mate or obedient student.

This technique was never taught by Imrich Lichtenfeld and Eli Avikzar because the knife can slide pass the elbow when you try to catch the opponent’s arm in your armpit and the blade can reach your body. 

If the attacker is committed and immediately tries to retract his arm backward like a pendulum for a repeated stab, it is almost impossible to manipulate his arm to an outer loop as he would end up too close to you.

If the student in the attacker role is not submitting to the defense and is retracting his arm in the same position for an additional stomach thrust resisting any forces implied upon, then there is no way this type of arm bar can be applied.

The problem is during demonstration that students are being submissive out of fear to get hurt by their instructors, or training partner, and if they got hit good and lost their ability to recoup and attack again, then any follow up pose will work. But if they did not then this technique is suicidal.

For instinctive defense you put your forearm 90 degrees toward the opponent’s wrist so the stabbing hand will not slide forward and stab you elsewhere and you simultaneously deliver a strike to the opponent’s face to break his train of thought and prevent him to retract and stab again in a slightly different angle.

If you see him coming with an under grip from a distance you hook your palm with all fingers on his wrist as you do a taesabaki to his dead side.

If you were already standing closer to his live side, then you do an instinctive defense with the front hand, switch your hands to grip on his wrist and continue with your front hand with a knife hand strike to his carotid artery.

It is recommended to finish the first move with a grip on his fist to bend him down and kick his groin and then peel the knife out, and then if you are standing in closer to his live side with a knee to the groin, and then peel the knife.

Is the trap you mention under the arm or pinning the knife hand to the shoulder with your hand/wrist after the circular defense? I understand this was never taugh, I am just trying to get the idea from the "negative demonstration"

Yes, I am referring to some people that teach to block with a circular motion instead of linear motion(with bent arm to facilitate greater catch)counter attack without continuing with a circular catch of the attacker's arm at his shoulder level. If the attacker is stabbing out of rage, or train to stab efficiently and repeatedly, defender in that case would cut his hand or while his hand is circling in the air, the attacker would stab him again and this time will succeed for sure.
