This is my third knife. It was from a large flake/spall from the outside of the stone. Some of the cortex is visible on one side. I really just threw it all together. I have 3 hrs in the whole knife( that probably shows). I had to stain the antler because it was sun bleached. It is hafted and epoxied. I put carbon in the epoxy to make it look like pine pitch. But that didn't work out that well, it gust got everywhere.
