For a sharpener, I have a Lansky ($35)that works really well. One sharpening every year will keep that Buck knife shaving hair. You can play games with the angles, and put a razor-edge on your knife (which takes some work) - or you can just go with a standard hunting edge - either way, it's a pretty nice system. No motors, failsafe.

I carry a folding Gerber limb saw ($20.00) for all my limb-cutting and bone-cutting work.
