I am looking back to see if I can find where I read this. (forgive me but I am a noob and do know know the proper terms) But I did read that the edge of the razor gets pretty torn up at the microscopic level after a shave. However if you rest the razor that edge will straighten back up. It is the same edge you straighten when you strop it.
I want to know how a bent piece of metal will just straighten itself back up, if it is true, and why.
