most folks when saving antlers, cut the skull with them intact, there are many ways, some like to cut in pretty triangles and or at special angles, pending how they wish to mount them, be it on a piece of wood, or screwed to a wall or??
then there are many folks that just leave the skull intact and lust clean that up really good, and bleach it white , or paint it
there are endless things one can do with them
I have also seen some folks just cut the antlers off real close to the skull, and mouth them that way, or use for rattling antlers, or throw in buckets
if you live close to a local butcher shop, stop in on opening day of rifle season, I am sure they will be cutting many of for customers and you can see how they do it!
or gather HAS to be videos on youtube of it as well?
