Kevin, that's a hard one to answer. Probably would take me a few days to boil it down to just three or four. But I can think of one of those, the only Warenski folder I ever owned.
I've heard/known of a few Warenski Damascus pieces that owners swore were forged by Buster(at least, that's what the sellers told them) . However, the expert on the subject is Julie, and in conversation with her, I found that Buster never forged any Damascus.
Buster used to save pieces of rock left over from dagger handle-making and give them to Shaun Hansen to use. As a gift, one day Shaun presented. Buster with the only billet of Hansen Damascus ever made that was not for one of the Hansens' own knives. Buster, I think I heard, made either two or three knives from that billet. Other damascus he used, he acquired by the billet.
Here is an image of that folder from that billet, which I will forever regret seeing pass out of my collection. Beautifully carved out of 440-C stainless by Julie Warenski, Edwards Black Jade inset. And 18K gold opener. And the surround carving is DEEP, no photoshop on this baby. An AKI piece.
Note the 24k gold beading on the sides, surrounding the entire folder.
