Oosik. Petrified Walrus baculum, or penis bone. Above you have a 22 inch specimen. And no, it doesn't get harder or bigger when you rub it. Excellent knife handle material. Polishes up nice. I've never used it before, so it'll be an interesting experiment.
Still torn between the mountain goat antler and this, bit I think I'm leanin' more and more towards goin' for the bone. Don't take that the wrong way.
