Oh Really?

So if I take a bar of steel and hit it with a ball peen hammer it will have a reised edge?

Neh, don't happen, the material compresses.

Better yet, take a hardened steel punch and scratch the bar, no raised edges there either.

Now if you use a center punch and hit it with a hammer you will get raised edges. Sorta the shock treatment.
