Not sure if that counts, it was more about the combination - but Juan Carlos Gomez had interesting way of throwing left uppercut to the body and following it up with left hand upstairs, on the inside. He was often drity with it, holding opponent by the neck with his right hand as He was doing it. In somewhere similar fashion - Muhammad Ali and Lennox Lewis were often throwing right uppercut while pushing opponent's head down with their left hand, effectively pushing their head into the punch. Zab Judah had his countering left uppercut. In itself maybe it's not that unique, but He was using it in unique fashion, punching with his opponent with knock-out intentions. I don't think I saw many other fighters using it in exactly that kind of way.
Ceferino Garcia - may have actually invented the bolo and was his signature punch, but Kid Gavilan made it far more famous. Dave 'Boy' Green - his 'muckspreader', which was how he threw his overhand right. Like a farmer with a pike or shovel. Ray 'Windmill' White - had such an assortment of punches such as his 'Rooster punch', his 'double-uppercut whammy', the 'kangaroo punch' and his very famous 'behind-the-back punch' Cyclone Hart - few fighters make you think of one particular punch. Sometimes it will be an assortment, but with Cyclone, one only thinks of a left hook.
Glad to see THE SMASH getting some love Here's this gem, a commercial of the Razor Ruddock endorsed trash compactor. This content is protected
Battling Nelson had his "Half Scissors" left hook to the liver with his thumb and forefinger sticking out. Illegal as H..., but it worked!
George Foreman had that step-in left uppercut that nearly decapitated Gerry Cooney. Seen him use it in other fights. Michael Spinks also had a nice lead left uppercut.
Does Floyd Mayweather’s forearm to the chest …while he nails you with his other hand …count as a signature punch ?
He was good at hitting and then holding- which is legal and Duran did it very often against Leonard. Good way of smothering someone’s aggression and breaking there rhythm.
