If you have any.
Start by removing each of the hooves at the elbow. With the point of your knife, find the joint and make an incision. Then, move your knife around the joint with the flat of the blade, cutting the ligaments and carefully working your knife around the elbow joint as deeply as possible. Twist the joint firmly and snap it off. Begin cutting through the skin at the base of the animal's skull.
Next, cut around it the base of the neck, then down towards the breastbone, and finally to the stomach, pelvis and the forelegs. Begin pulling the skin off the shoulders and neck, working your way downward toward the chest. If muscle tissue is pulling loose with the skin, scrape or slice through it so it doesn't tear loose as you go. Slicing the subcutaneous membranes will make the skin easier to pull free. Pull the skin off the carcass, either with a vehicle or by hand. If skinning by hand, pull the skin down a bit, then slice the tissue that attaches it to the muscles underneath it, working a little at a time. Tying a golf ball underneath the skin to pull with. If you want to save energy and use a four wheeler or even a truck, you can tie a golf ball or a similarly sized stone under the skin, looping your rope around it, then tie the free end to the vehicle. Drive slowly away from the carcass, pulling the remaining skin from the deer with very little effort.
Next, remove the head. Take the deer down and lay it out on a flat work surface. Just under the jaw, cut the ligaments to loosen the connective tissue around the neck. You'll need to twist the head sharply to break the neck and remove the head completely. If you want to save the antlers, but not the head, you'll need to use a saw to remove a portion of skull about an inch from the base of the antlers. If you want to save the entire head, keep it cool and skin (see below) it. Save any meat from the skull you wish to keep and boil the skull for several hours, removing the tissue and bleaching the skull. Clean it afterward with hydrogen peroxide to get it white.
Rinse the deer's carcass after the skin is removed. This will wash away any hair that has stuck to the meat and will also help cool the meat while you are completing the job. If you plan to have your deer commercially processed, it's ready to go to the processor after removing the organs. If you want to break it down yourself, let it cool thoroughly and take it indoors or to a clean cutting surface on which you can work.
