I agree with ironraven. We took a group of scouts on a backpacking trip. My leatherman was used twice for on trail for last minute pack frame adjustments, once for needle "assist" in repairing some webbing that came unstitched, and once when a hipbelt buckle split. I used zip ties to cinch the buckle back together, but the pliers helped get them tight enough so that the male end didn't slip out.

I compromised due to weight considerations. I really wanted to carry my Wave (better file & saw), but ended up carrying my original leatherman. I carried my RSK in my pocket, but my leatherman was in the pack. Very handy on the trail.
