Re: Skinning knife
Perhaps the best knife I know of is any inexpensive "utility" or "box" knife with interchangeable blades. Get a set of the hook blades for splitting the skin, use conventonal straight blades for other cuts.
Use your truck, a tree, two 25 Ft. lengths of 1/2" nylon rope, a two inch rock and a truck to remove the hide, not a skinning knife.
Tie one rope high up around the critters neck, then hoist it onto a sturdy tree limb of the right height to get the rear legs just clear of the ground. Use a hacksaw to remove the legs just above the knees.
Cut the hide around the neck just below your rope. Slit the belly skin if it hasn't already been done, and inside the legs too. Pull a loose patch of skin from the neck, above the spine. Insert the rock in the patch, tie the rope firmly around the rock to form a secure pocket. Tie the other end of the rope under your truck's front bumper, then carefully back it away until the stripped carcase is swinging and the hide lies on the ground.
Perhaps the biggest mistake is to use a rope that's too weak, ESPECIALLY for the rope that lifts the critter; if that rope breaks the deer will be deposited on the ground, immediately! Ditto the choice of tree limb to suspend things, a too small or rotten one will give the same result.
I haven't skinned a deer "right" since I was taught this method by an old man back around 1970. Now I"M the old man, passing it along!
After you learn how to hang the deer and tie the rock in place securely you'll pretty well have it licked, no sikinning knife needed. In fact, I haven't owned one since learning this method. Skinning is done in a couple of minutes and little hair contaminates the meat, and most of that is from the edges of the field dressing cut.
I use a conventional hunting knife to quarter my meat as it comes off the carcase. The hide and bones are bagged and discarded together.
