I am planning to do a couple of knives for a friend using the antlers off his first moose. The rack was small so he thought making a couple of knives with it would be a nice way to "Mount the memory" if you will. I have seen the precautions about cutting antler and was looking for a bit more detail. Can this be done well with hand tools? Also would it be best to have some sort of liner and if so what? How old should the antler be, by that I mean how long should it have been off the animal? These have been in a heated garage for the winter since he got it last fall. I am hoping I can get the slabs I need out of the main beam so as not to deal with much pith. Also he would like to save as much bark as he can on the slabs. These are going to be users but I would like them to start out life as nice as I can make them. Any help and direction you could give me would be greatly appreciated.
