I'm still after one
I just ordered an Air Force survival knife from Amazon today. There might be better but it just seems a classic icon with the saw back and hammer pommel. It seems like such a general outdoor utility knife.

I had a Camillus that I loved but someone liberated from my car. The pommel makes a good hammer and the saw back sucks as far as cutting branches but it was designed to cut plexiglass.There are holes in the guard so you can attach it to a branch and use it as a spear.I really really like this knife even more then my Marine Recon Ka Bar.
