Is the "Corkscrew punch" the defacto/regular punch in boxing? It seems like most boxers are doing this anyways in their jab/cross punch, where wrist is rotated and thumb is slightly angled down. Or is the corkscrew punch a totally different from other jabs/crosses they teach in boxing? This question is more about dictionary terminology in boxing.
"Corkscrew punch requires you to rotate your entire arm, right from the shoulder to the elbow, all the way to your fist. The term Corkscrew punch was invented by a popular boxer Charles “Kid” McCoy, active between 1891-1916."
Wing Chun and Krav Maga teach slightly different rotations in boxing.
