I can't say for sure, but I doubt that Buck did that. I've seen that company sell other 110's with stuff like the Corelon handle with a dollar bill on it. I think they have them done by someone else. Like the seller on the auction site that has all those Corelon handled 110's.
As a matter of fact, I just checked that auction sellers listings and I found a few with almost the identical Corelon handle material but with different logos and blade etches. I'm bettin' who ever does them for that seller does them for SMKWs too.
