Bone for carving

[Dan D'Silva]

I'd like to make a bone chape for my new akinakes scabbard, something like this: http://www.louvre.fr/en/oeuvre-notices/dagger-chape

I understand I need a white knuckle end, but the ones I've found for sale (they are beef bone for dog treats) are roasted or baked. I understand bone for carving is often boiled to clean it, however I'd think dry heat would bring it to a much higher temperature. Would it then be too brittle for carving? I'm looking at products like these:
