Very interesting! I’ve seen this grip in various wrestling/grappling contexts and also in Silat, and I have practiced it in a combatives context against the knife. They called it “the Russian grip”, in lack of a better name I guess. Does it have a name?
One of our guys starting using it years ago and it's just kinda stuck with us. I'm not sure where he got it, but it's an awesome control and quite painful
