Dammmmnnnnn....
Reminds me of a story I read once. The hero is this incredible guy (and a thai boxer

), but the villain is built like a freakin' gorilla, and he once kicked the hero's ass to the point he gets the shakes just thinking about this guy.
So the author sets up a situation where the hero has got to fight him again. And win -- he was going to just let the guy kill him and get it over with, but there's someone else's life at stake... anyway, he realizes that he's been thinking "once that guy gets his hands on me, it's all over." And suddenly understands what he has to do.
He takes out the guy's hands.
He then smashes him up pretty much the way you describe, and finishes with a judo throw that pile-drives him.
The author does hand-to-hand like no one else I've ever read. Judo, kobudo, swords, small-arms, backhoes (!).... His name's Peter O'Donnell.
