Hi. I recently did a thread where I found out that if you do a boxing punch in the wrong way you can break your hand bones (metacarpals), the ones of your 3rd and pinky finger. My question is: is the wing-chun chain punch safe, as you hit with the ring and pinky knuckles? I was thinking that if you bend your hand in the right way then you may be positioned so the bones don't break, but I am not sure. Any opinions on this?
