still learning said:Hello, I read somewhere it only takes about 7lb of pressure to break a collar bone. Usually a hammer blow or chop.
A collar bone on its own, no muscles or tendons or other things, just the bone out of the body, 7lbs seems plausible.
But put a 7 pound weight across my shoulder and it's not going to break. It's going to take a really hard blow to break it, especially on someone who's in shape.
