I have watched Reese finish a knife in the shop. He uses a 10x power glass to inspect.

If the knife you have is for use, a nick or scratch on the frame is acceptable. The blade edge is the important part. My wife carries a Tony Bose Trapper she got as an anniversary present. It fits nicely in her back pocket without a case. Makers love to see use but cringe at abuse. You are the best judge of what works for YOU.
