I found it, I found it !!!!!!! In the thread - What arts are incompatible with each other? in Post 89, there is a link to where the double slap is shown about 1:47 or so. It worked! then the demonstrator grabbed his opponent's hand in mid-air (Isn't he good?) (!!!???) and applied a wrist lock into a throw. Sir, how could you put down a nun who obviously had that technique down pat? Well, minus the fact it would break knuckles, wrist, elbow/shoulder joints, and parts of the body slammed to the ground. Actually I wonder if she found that same video on the i-net but didn't want anyone to get hurt when the wrist lock and throw were applied. That part of the displayed demo was I think was very sloppily underplayed as to what it was supposed to do. In fact I am not positive. But I think the idea was to break finger knuckles (since I have learned applications of that in Hapkido) and then move into a grab of the hand like you talked about (not in mid-air), and move into the wrist lock and throw. So now I think I know what she thought she was talking about. Wow, how did you sit there without laughing uproariously or at least snickering loud enough for all to hear? Your Gi must have been very strong that day.
