Because of the vigerous weight training and boxing I do, I understand the power behind a jaw punch. I would not use it if in a situation where someone is throwing strikes, but it'd be perfect for the situation described.
"Ninja i hope this doesn't offend but rather than risking a head but that in my opinion means you to sacrafice speed for power, why not try to break their nose with a punch or a palm heel? It may not have the same power but its so much faster than a head butt that could be telegraphed."
Because if performed well, a good headbutt would not only do the job, but also have the element of surprise that a punch or palm heel to the nose wouldn't have.
Of course though, I would use common sense before self defense. Depending on the attacker's size and energy level, I would try to just submission him with some basic hapkido defenses.[/QUOTE]
Use the jaw as a lever to send an blow to the nerve centers in the brain that'll take him out. Another technique that is very effective is a backhand slap to the temple. If you don't knock him out, you'll make him dizzy, but be careful it can also kill him if you use too much force.
