I use bone a lot. It can be a tad brittle as to pins, or rivets, or if accidentaly dropped on a hard surface. Other than that, it works easily with a file, or grinder, just don't overheat it. It can be stabilized, but I just wipe my own bone gripped knife with mineral oil every now and then. I like it, some don't. Deer leg bone is to thin for all but small grips if slabbed, but if making a hidden tang knife, can be fitted, and epoxied over a wood core, and be very strong. It often chips out upon drill bit exit, but there are bits designed to prevent, or minimize this. Or you can stop just as the very point emerges, and then finish the hole from that side, with a very slow entry. Pins must be no tighter than a push fit at the least, or you risk cracking. It sands well, and polishes beautifully.
