One of the most common mistakes hunters make is cutting the capes too short. Along those same lines, slitting the throat in any manner is also considered a no-no. In addition, hunters should avoid slicing the ears in any form, especially during the process of tagging the animal. It's recommended the hunter place the tag on the antlers instead. Putting the tags in the ear is probably the biggest problem.
People get all excited and stick the knife in the deer's ear.
Anytime you can stop cutting holes in the ears, the better off you're going to be. Don't even let them put the tag in the ear at the registration station. The proper technique for skinning a deer starts with cutting off all four legs at the knee. Then use a sharp knife and cut between the white and brown hair on the back side of the leg, staying along the outside of the white hair. The hunter should then peel the skin off the legs and hang the deer by the back feet.
