OK, I don't know if this idea has been posted before, but to keep my knives from to much excessive damage and wear unless its an emergency, the one tool I take with me if weight allows is a small "wrecking bar"/crow bar/pry bar. It does the prying of big and little things and lets my knives do knifey things. One usually goes with me on most trips, lots of rocks around, and some times a small mattock. They usually stay in the main camp and they end up doing a lot of jobs. Using the right tool for the job is the idea, but well many times one has to improvise.
