I usually only bring a swiss army knife (farmer or huntsman) when backpacking for trips where I'll be hiking full days (10-20 miles depending on elevation change). I like to keep my weight to the absolute minimum while still being comfortable when I stop hiking, and a fixed blade has never been necessary for my comfort.
If I did bring a fixed blade it'd probably be a mora 510.
Most of the through-hikers on the AT that I've met have just carried a swiss army classic or a leatherman micra.
I guess some people just need to hear themselves talk (or see themselves post). (If there was a "useless/pointless" smiley, I would use it here)
