I have been using a Leatherman Wave for ages. It has never let me down and I use it a lot. Just yesterday I used the serrated blade to cut some conveyor belt...above it's design parameteu but it got it done.
As a side note... I actually own two. I had one for many years and I lost it. So I bought another, then about a year later found the one I lost while fixing my driveway from flooding. Even laying underground for a year, I just soaked it in oil, wiped off the mess, and it's good as new.
