Kata-ha-jime

(single wing lock)

This lock is applied against the same defensive position as the straight arm lock. In this strangle, insert your left hand under and round the opponent's head to catch his right side collar as deep as possible. As you do this thrust your right arm under the opponent's right arm and down past the back of his head. As you do this, lift his right arm up to apply pressure, pull up strongly with your left hand and shove your right arm deeper past the opponent's head. The thickening of your right forearm will gradually force the opponent's head into the lock. Keep the opponent close to your body and don't give him a chance to unravel his arm right.
