I usually carry a folding knife over a fixed blade as they are much more compact and very capable for the job. I use to have a fairly inexpensive coleman western with a synthetic handle but got the great idea of buying a new sheath as the old on was getting torn after many years. Yep 1st time out the belt loop on the new sheath came loose and lost them both. I have since used several others but mostly a gerber lariat series that has a single drop point w/ composite handle. Now discontinued, they can be picked off ebay for around $20 and they work fine on deer. Since we mostly are hunting farmland deer I usually just field dress the deer and have butcher knives and saws back at camp so a big knife isn't really necessary. I have used a standard 2 bladed trapper before.
