Ancillary Kebonsu

Up

For each of the basic "core techniques"--"KEBONSU" there is an ancillary technique intended to show a comparitive or contrasting use of the biomechanics. These ancillary techniques are presented here in the same order as the primary YON MU KWAN core techniques. 

 

 

Ancillary Technique #1 : Armpit Arm-bar

Drill: The attacker executes straight grab to the wrist. The defender counters with a rising motion, trapping partner’s wrist in the webbing between the thumb and forefinger of the defender’s lead hand from beneath. Defender’s trailing hand arc wide between attacker and defender and traps the partner’s wrist from above in the trailing hands webbing. In a 180 degree pivot about the partner’s wrist the defender’s wrist slides over the partner’s arm, and the partner’s lead elbow is snugly held in the defender’s armpit as rising pressure is applied to the partner’s lead wrist. Emphasis is added with hip pressure induced by collapsing the defender’s knee in the direction of the partner’s shoulder while strongly flexing the partner’s lead wrist towards that same shoulder.

Points to Ponder:

·         The focus of this technique is a balance between the stabilizing pressure exerted by the armpit on the elbow joint and the lifting pressure applied at the wrist joint. The dynamics of this motion often invites the defender to compromise his balance to gain additional effect. This is evident in beginners who have not yet grasped the simple effectiveness in accomplishing this technique with equal effort of both the shoulders and the hips.                   

 

                                                                  

Ancillary Technique #2 : Two-finger Projection

Drill:  Attacker applies cross-hand wrist grab. The defender responds with sharp downward tiger mouth strike to the partner’s wrist simultaneously clearing the defender’s lead hand, and grasping the partner’s wrist. The defender’s cleared lead hand cups the back of the partner’s hand with palm heel aligned with the partner’s first row of knuckles. Pressure on the back of the partner’s hand combined with restraint of wrist induces pain at the wrist joint as it is hyper‑flexed.

Points to Ponder:

·        This technique is named for the two-finger placement which is on the end of the forearm, yet, not in support of the partner’s wrist. The wrist should not be encircled with the defender’s entire hand, as this defeats the mechanics of the technique.
