Thanks,
Since my jaw is made of steel that is certainly something I should worry about!:roflmao
Seriously now, I tried the vibratory tumbler idea for restoring blades. I wasn't to impressed. One of the things that I noticed when I tried two blades at once was that they became magnetized and stuck together. they didn't bang each other and chip edges etc. but they stuck together so the media didn't rub the one side. I have them left over from the experiment still in the garage. I will have to give them a closer look before using a more traditional restore procedure.
