The two I have found most useful are the Kershaw 1670blk, and the Schrade 6 inch "Old Timer". The Kershaw I carry as a clip on pocket folder handy a half dozen times a day. The Old Timer I've had for 20 years or so and I've field dressed, not skinned, at least a dozen Whitetails with it. Both blades sharpen easy and stay sharp. I don't carry a "Combat" knife since I don't plan on going into combat.
