My current knife is good for about 2/3 way through a deer (or, like I said......I just need a better sharpener).
I would like to add that the ability of a knife to hold an edge is a function of the quality of the steel used to make it, not a matter of a good edge to start with. Harder steels, like that VG-10 I mentioned above should hold a very sharp edge with a lot of use as compared to a lesser steel used in a particular knife.
