is a beef bone, disinfected and well cooked. I left the base with the hole.
finished slightly mechanized, and then manually, 20 grits. It still has imperfections, but the perfection seems boring.
I think I forgot to attach a movie or ... disappeared
Very unique. It is probably fine just as it is, but the hollow area could be filled and the exterior could be sealed if you want to refine it somewhat more.
