I am kind of new to field dressing but I am looking for a good hunting knife for just that task. I have used cheap knives in the past and have lostfew along the way. What i am looking for;

1. Under $60
2. has to have a leather or nylon sheath (lost too many to belt clips)
3. comes out of the package sharp and stays sharp
4. Sturdy handle with something to grip

I have been using a 3.5" blade. Not sure if that is correct but it works for me. Can anyone give me any suggestions? i am ready to pick one up atthe local gander, cabela'sor online.
