Hello, I had a question about a bone handle I'm working on. I took on the project of a viking style of knife and have a brass-antler-wood-bone-brass sandwich going on, that I'm going to carve some designs into. The only antler I have is a bit too big for the handle and I have to sand it down. I was just wondering how far I can go, and if I can go into the slightly porous section without completely trashing the handle. Thanks.
