I'd steer clear of the ceramic knives. They don't enjoy the best of reputation in the knife world. The blades are extremely brittle and the edges are prone to chipping. Resharpen? Don't think so.
There are many good knives which will field dress and skin more than one buck before dulling. Take a look at Bob Doziers D2 steel hunting series of knives. With Bob's famous heat treat and cryo stress relief, high hollow grinds, comfortable handle designs, these are working knives with class. They will handle several deer with competant knife handling skills. They also touch up fairly easily on a Spyderco Sharpmaker. Neil Blackwood makes a great blade also of D2. Scott Cook uses several different blade steels, I like his BG-42 and have a new custom ordered from as we speak. I tend to favor smallish fixed blades for this job. They're strong, easily accesible in a nice horizontal hip sheath, and clean up quickly. A few other good steels to consider would be ATS-34, VG-10, 154CM, CPM440V, the Marbles line of knives utilize 52100 and it's a great steel at a good price point.
