Have y'all ever heard of the DaveHax method? It's named after the popular YouTuber who often uses a 1000 degree (Or near 1000 degree knife) to cut a large variety of objects. I've personally used this strategy to melt the meat right off the bones. I recommend getting a few blowtorches (To get the knife up to temperature) then holding it over the excess meat. This will slowly burn off the meat and leave you with a cleaned bone. After heating, you freeze the trophy at a very low temperature (around -30 works best, for me at least). That'll get off the last remaining pieces of meat and leave you with a clean trophy.
