The knife I actually use the most as a camp knife is my Battle Rat, although it's on the large size for hiking. DogFather, NMSFNO or FSH works here too.
My favorite heavy use hiking knife is the Camp Tramp (SoD works in this slot but I like the SR101 on the Tramp). SFNO works here too.
If I don't want to scare people, the biggest knife that I'm comfortable carrying on my hip is the Desert Jack.
