Opponent attacks with a stepping right cross targetting your head -

Move 45 degrees left of your attacker, Inside Windmill parry (double hand parry, Mawashi Uke) 'Apply footwork, We in SK take up Sanchin Dachi' - The windmill parry should have allowed you to grab the attacker's arm at the wrist (apply pressure to H6). Now pull to Hikite (Right fist at hip).

As you do so Inside forearm strike to elbow joint or (TW12). Meanwhile rotate the wrist clockwise (employ body shifting, change of stance from Sanchin to Horse stance During the forearm strike). The attackers arm has now been shifted across your body as in Matts description.

Now we apply a typical Kempo technique!! With your left arm Strike at TW11 with your forearm As in downward block, but carry the force of the strike and use the Hammer fist to strike SI17. Hopefully this will induce a KO...

If not carry the technique on with a Right Vertical Cross to GB20 followed by a palm heel to LI15 to push the attacker away. This Is Called 'Grabbing Hammers' or NOW 'Grabbing Hammers Variation *1.
