i come bearing good news. Just look up "swedish mora" knives. they are cheap, high quality and will do what ever you want. Many styles etc..
i have AG Russel knives, schrade, buck, etc.... i find that a good metal (440c, 154cm, AUS8) is important. AS far as lenght, IMO 3 to 3.5" in blade length is perfect for me. I also prefer a fixed blade for field dressing. Easier to clean, no worrying about folding failures, freezing up and cleaning blood and hair out of it.
here is the mora knife. this came to me razor sharp and it made from carbon steel.

give them a look. i bought a few just in case i lose them. I usually look to this knife or my AG 3.25" blade knife.
