None of the designs shown will make a good skinning and working knife for a hunter. You need a dropped point, approaching a small spear head shape. Look up the "ripper" blades that are made by Russell. There is no better shape for working critters. Trailing points are near useless for a hunter that will do his own work. A dropped point turned up, will open an animal like a zipper, and will aid in not cutting the gut, or anything else one does not want cut. I have about come to the conclusion that many knifemakers, who make hunting knives, do not hunt, or they do not work their kills themselves, or they would not make some of the weird hunting knives I see. If in doubt, ask a wild game processor. Other than that, shapes, and tastes vary widely.
