This is so completely variable... for what situation? Winter, spring, summer, fall, desert, alpine mountains...? With winter coming up my go to tool will be a 26 inch Wetterlings SFA. Even pine when frozen is just too much for a knife-your joints will look like the spine of your blade by the time you get anything accomplished. Went up into the mountains today to play an epic round of Capture the Flag with some school buddies. The girl I drove up with lost her keys, and everyone else had left. We were 8 miles from the nearest person through some gnarly pine scratch and high desert. She took a pen light and a radio and went looking over the square mile where we had been playing, in vein hope of finding her keys. I set to work with the Condor Hudson Bay Camp Knife in my daypack splitting wood for kindling and making a bow-drill kit. By the time I'd finished carving my notch she comes skipping over the ridge dangling her keys, but in a situation where 15 minutes out of town means some serious country, you'd be stupid not to carry a good knife in your backpack. A hatchet however, in that case, is a little too big for the intended purposes. It really depends on the situation-the application of common sense is enough to answer your question.
