First of all I don't know what to call this move, thats part of my question. But also I'm not sure if its even a lock. Right the attacker grabs your wrist, you place your free hand on top of the attackers hand (the one of your wrist) then hook the subdued hand around the attackers arm and push down and towards yourself. This creates pain in the attackers arm and makes them, in extreme cases, lower onto their knees. I like this move and I am curious to know the name of this move and whoch martial art it comes from, also if there are any other small moves like this
Fur Kampfkunst, das ist mir egal.........und du?
