Don't take it personally but I'm sure they can take your head off with a couple of not so hard punches
Lamon Brewster has ridiculously small wrists and hands for a heavyweight, yet he's a murderous puncher.:smoke
LOL@ the video, Pac keeps copying what Cotto is doing.... what belt is Pac holding? Is it on the line or somthing?
Damaging punches from small hard hands makes perfect sense. The force is focused into a smaller point. Same reason that if you get poked... an ice pick goes through you (fine point) and the end of a baseball bat (wide point) would just push against you. Same force on a smaller surface area equals more damage. Also explains why the smaller guys hurt their hands so often... Less structure to spread the shock of punching.
