The part where he grabs the body and the head, trying to dismember the head from the rest of the body by pulling them in opposite directions. It'd seem obvious, but I can't see that grab getting him anywhere though.
I asked in which video and not when. I'm quite sure they aren't tearing uke apart. They are breaking uke the common way.
I apologise.
Anyway, I made a replay which somewhat looks like a tear, but is actually a break on impact. I also noticed you're using huge turnframes, too. That might be a problem.
