Well so far I've been carving the horn with a dremel and a high speed bit. Gotta love the dremel for this, wow does it do a number on horn. You can mess up real fast if your not carefull.
I appologize for not having pics, I don't have a proper camera yet, so I'll do my best to explain what I'm doing. Anyway I'm taking the cut off tines and smoothing those as well, one is going to be the hilt for a sgian dubh that I'll be making. Another tine with be turned into a walking/hunting staff with a fork on the top for ones thumb or to rest a rifle on. the rest of the cast off sections I'm going to turn into horn toggle buttons for some project down the road.
