I have a Leatherman wave and crunch. I found the crunch to be really handy and it's usually my urban EDC, on the boat etc. Saltwater causes a bit of staining but no major problems so far.

The maul-grip feature is surprisingly useful and I find it can pretty much do what a normal pair of pliers can. The only blade is serrated which is fine for most of the use it normally gets, but I supplement it with a decent fixed blade if out cross country.

I love the wave, esp. the diamond coated file & one handed blade opening but find the crunch fits the bill more often. Also the U.K. is getting more & more painful about any EDC now, so the crunch is less "dangerous" looking and I'll probably mod it so the one blade doesn't lock to be 100% legal!
