Like I said! I had Kelly do a phoenix bird on a case hardened side plate of my '76. I showed him the one I wanted, he did a quick sketch, I approved it, he traced it onto the metal, and free-handed it with a hand graver. The whole thing took less than 30 minutes.
I've seen him do names on back straps without that much preparation, and all of his work is beautiful.
It would help if you had a picture or sketch in mind, but he can work from nothing more than a description and come up with something you'll be happy with.
