The first thing a good mechanic learns is to use the right tool for the right job. I'd bet 99% of taxidermists have used that flat tip screwdriver to remove the skin from the burr of deer and most of them, at one time or another, have skewered their other hand or come damned close. Go to your local hardware store (NOT LOWES OR HOME DEPOT AS THEY DON"T HAVE IT) and ask the man (or woman) for a 1/4 inch cabinet chisel. With this tool you can hold the stem of the blade between your thumb and forefinger and scrap the hide out from under the burr of the toughest old whitetail so easily you'll be shocked. Keep it SHARP. It will work exceptionally well on aoudads and sheep or on Africrap like the buffalo and the kudu where the base of the horn mates up to fleshy cartilage as well. I used a "Buck" chisel for over 50 years and it was about half as long when I finished as it was when I bought it. Kept an edge well and worked on the toughest of hides.
