I don't know how big yer critters are. For (many) years I have used plain old Buck 121, 105, 102 or 118 pattern knives with black phenolic handles. No glamour here, but they sharpen up well, wash up well, hold an edge. This is for deer and pronghorns, and I have gone through (literally) 200 to 300 for myself and other people. If I was doing elk or moose or cattle on a "more-than-one-or-two" basis I might look at something else, like (duh) the 119 pattern. These are very reasonable in price if you shop the old auction site and do it smart. Used ones with some blade loss will easily last scores more years, more than a lifetime. I love non-stainless steel knives to collect and even to use a little, but, really, not in the kitchen or the boucherie. Anything beyond the basic Buck knife is certainly fine, to appeal to your sense of aesthetics or whatever. I think a seamless surface over the whole knife (no wood, no cracks, interstices, jigging, etc.) is good for cleanliness. Also, against all logic, the (overall) safest cutting boards are WOOD. (yes, yes, I know). Believe it. And read about it in one of the links Bernard Levine provides in his subforum. These are just my opinions, based on a lot of years, but you might get some better advice from someone younger, and therefore wiser.
