[QUOTE=J Miller;5674094]Oh yeah, in Phoenix, AZ it was called "Operation Identification". Just call the Phx PD at 602-262-6151 (still a current Phx PD non emergency number) and they'd loan you an engraver.
I had my own engraver and put my drivers license number; D-111X1X all over my tools. They got stolen and I've never seen a one.
It was a waste of time then and still is.
I can tell you the other side of this story. I didn't engrave my stuff and it was stolen. The police recovered some things and I couldn't prove it was mine. Sometimes you just can't win!
