I didn't stabilize it. Since must of my bone is reclaimed from my friends ranch it has sit out in the open for long periods of time. I clean the with TSP, shape them , and then color them. I use leather dye to create dark tones and contrast. Followed by dipping them in potassium permanganate. Dip, wipe dry, and polish until I get the effect I am looking for. I do put hidden 416 SS pins in the tang. Also the epoxy I use is West Systems GFlex.
