I still have an original stainless one that I use all the time. Hoyt fo Life555 is correct in that top blade can be scary if you don't pay attention, have a slip, or don't have the cover. I use it mainly for the hook and how well it rides under the skin. That top blade is pretty good for skinning the rest, but I find myself putting it down and using my other knives lately once I've "unzipped" the animal.
If you just want that hook function and don't want to worry about that top blade, I think it's Gerber that makes one without that. I'm not completely sure on that brand, I just happened to find one in a recent purchase of a bunch of used hunting gear from someone quitting hunting. That model is shaped just like the WK, but without the top blade. It is also made to use those replaceable carpet knife blades, so that's pretty convenient. If I get time later, I'll dig through that box again and get the brand name.
