SL2.4 Outside Birdwing Lock (AKA Double Wrist Lock, Kimura)

This technique can be deployed from the ground, turtle, or while standing. It may be the most versatile lock you can have in your arsenal. This technique was named for Masahiko Kimura a legendary judoka. He was a seventh dan in judo and karate. A true master of all three ranges of combat. Kimura’s O-soto-gari was so fast and powerful that, in randori, he occasionally knocked his opponents’ unconscious with only the throw. Yes… he is the one that broke Helio Gracie’s arm during a match in Brazil. Sadly, he died in 1993. His style of karate was Goju-ryu one of our sister systems. Yes, Frank he was one of our inspirations.

Warning: This technique should only be practiced with a qualified AOKK instructor present.

• Trap uke’s hand and snap punch to ribs [Loosening-up technique]
• Push uke’s hand downward.
• Wrap your punching hand over uke’s arm and tie-off to your wrist.
