I was looking at one of today's DOTD postings, a Bhaspati with a bone handle, and found myself wondering about the properties of bone and how one should maintain it. I wonder if bone has the cracking problem so common with horn handles when they dry out? Or any other issues that require a particular kind of maintenance? I have khukuris with wood and horn handles. For horn I use hooflex, for wood I use tung oil most of the time, and for the blades, mineral oil. For bone I wouldn't know. I tried a quick bladeforums search on the subject. Got a large number of hits about bone, but not much about how to maintain it. One thread had many postings on the subject. Unfortunately the posters tended to disagree with each other on almost every aspect. Some recommended mineral oil, while others said bone wouldn't absorb it. Some said to use clear paste wax. However, I know from experience that paste wax sometimes makes a surface very slippery, which is not good for a knife handle. Someone wrote that mineral oil can discolor a bone handle. That wouldn't necessarily be a bad result, but it might be too unpredictable. Would anybody with experience care to weigh in here. Preferably not speculation, but actual experience. Thanks in advance.
