No, you don't understand - The marks showed up while using a breaker bar in opposing force. I watched them appear. - It was freaky.Whatever that is on the bar it isn't stress fatigue. Looks like scratches from your vise. Bar looks good. I don't see a problem. Put a breaker bar on the crank. Use a socket not the square hole.
