I like the Russell Green River blades. They are inexpensive, versatile, and sturdy. Though I have a few very fine knives, I like to use these Russells most of the time.
The one I normally carry is called the "Hunter" and the one I like to use for skinning elk, deer, or antelope is called a "Fish" knife. They are inexpensive and rugged. Since they are carbon steel, you can hit them a few licks when doing a big job and put a wire edge on them very quickly.
Here is what the "Hunter" looks like, it has a 5" blade:
And my favorite skinning knife, which has a 4 1/2" blade:
I have batoned them through wood when I needed to split wood for a fire inside a tent, and they have never disappointed me. Very dependable...you could dig a rabbit out of hole with one and replace it when you got home for $20 if you had to. Highly recommended.
