wire inlay

If the pro engraver did mostly guns, it's not generally a good idea to anneal, engrave and then Re-HT a gun, whether barrel or reciever, too much rish of weakening or warpign it in some way and turning it into a murder waiting to happen as it blows up in the users face.

Even if a Pro did the anneal and HT on an engraved gun I'd be avoiding buying it myself. I've seen what happens to guns exploding.

Exactly -- he wasn't doing any anneal/HT on the guns, just engraving into them. I guess guns aren't generally as hard as knives.

It just seems to me that if you're engraving into a blade before hardening, you should be worrying about stress risers. A channel for wire inlay is a sharp edge cut right into the blade. Guess most people don't worry about this?
 
The gun barrels are generally about HRC 30, receivers the same, working flats are cemented to achieve hardness, whilst the core is still soft and tough.

The stress on knife is not nearly to few percent of stress of the barrel or receiver during the gunshot.
