Danbo, if you'd left off the word "just" you'd be right. The semi-skinner is the better knife for skinning large animals (deer -- mule deer, not those little whitetails I've seen! elk, moose, etc.) The drop point versus the semi is a wash for smaller animals. For actually removing meat from bones (muscle boning) the drop point is probably better assuming it has a blade less wide (spine to cutting edge) than the semi-skinner.
When buying a hunting knife (and I'm using the word "hunting" to mean harvesting game animals -- not "camping") the blade shapes like the ones used in packing houses are the best ones -- sometimes buying packing house blades like "Forschner" is the best thing.
