Was looking at getting a Buck 55 from A.G Russell with the "mammoth ivory bark" scales. Ok what exactly is that? I would guess its the outside layer of mammoth tusk they have found in the artic. Does anyone have a idea if its durable/waterproof or is it just for the collector's case? If its is as durable as sambar stag I might get one just for the thrill of carrying around something that unique and beautiful. Anyone that knows about mammoth ivory bark please respond! Thanks!
