I found this item at a gunshow, and have no idea what it is. It is made of bone, and as the dimensions show , it came from a very thick walled bone. I'm thinking something African. Elephant, Hippo, Rhino? I've been told, that whale bones aren't that thick. It shows evidence of wear, in the "sharp" end. Like being used as a scraper. I doubt that, as it is very uncomfortable in your hand. I'm thinking something talismanic. Any ideas?
