That was engraved by Fred Carter of Wichita Falls, TX. There are photos of some other
he has engraved if you search through the Forum. Jurphaas has a Kopa and a couple of Crickets engraved by Fred that were inspirational for my wife and I in deciding on this as an anniversary present.
Fred also does some amazing custom knives, something I had not really been aware of beforehand. You might enjoy looking at the book by David Darom: "Art and Design in Modern Custom Folding Knives". That was an eye-opening experience for me. I picked up David's other books on custom knives afterward.
Best regards, and Happy Labor Day,
