Lots of lessons and examples to be seen in this video:
He went for the kill shot with that stab to the side of the neck. He wasn't mucking around and stopped when belt guy backed off instead of then becoming the aggressor.With just one swipe a knife fighter can gut you like a fish, don’t want to tangle with one either.
whats a comma cut?If your going to pick a fight, and be the aggressor, please make sure you bring more than a belt and have some semblance of h2h skills. As we note in the clip, the knife guy didn't have to make much effort to insert it into his neck when belt guy came into range.
If knife guy really knew what he was doing, he'd have used the comma cut and the clean up on aisle 5 would have been drastically worse. Not to mention shortened the time belt guy was upright/. Where it was already inserted, the comma cut's a no brainer.
