I love Sambar Stag, for me there's nothing that comes close. I buy stag when I see it and supply it to the makers I work with that don't have it for the knife I want. Good stag is getting a lot harder to find. I have stag for four more knives, after that I'll go to makers that have a good supply of stag and some of course do.
I read an article back in 1998 that said that makers who offer stag knives needed to have in stock a ten years supply. I'm sorry I can't quote the source, but if that was based on what the makers were saying at that point, there should be makers that still have a five or six year supply on hand. I wouldn't blame them one bit if they charged a premium for that stag.
