I bought two stealths a few years ago off the classies. From two different people.They where both older with the shallow engravings. Both had scratch marks from someone using pliars with no protection on the jaws. I can buff any scratch's out after sanding down first but guess what happens to the shallow engravings? Pliars are a GREAT way of screwing up a beautiful mod that is for certain. If you need to use pliars they need to have protection on the jaws! A rather simple way is heat shrink from say Radio Shack or else ware to leave on a pair for GG use.
