the oil will keep the dye in the cuts
when ever I do any scrimshaw (wood, bone or antler), I mix powdered ink or charcoal with oil and rub it into the cuts. I've had the lines fade a little with eating utensils, but I put that down to the frequent (soapy) washing and the fact that the oil I use doesn't set very fast (flax oil). When I use danish oil it sets fast and so locks the dye in place nicely.
