It turns out that the infamous anti-immigrant gang leader, nicknamed Bill the Butcher, was also a bare knuckle boxer. How good was he?
He was more anti-Irish than anti-immigrant. From what I read about the guy he had cruiser weight size and always preferred a bare knuckle bout so he can gouge out your eyeballs later with his fingers. The most notorious thing he was known for according to History is he loved biting another mans nuts and ripping them completely off.
