I think it is worth considering the weight of the tools you are packing, versus the complexity of the mechanisms you might be dealing with. If I am backpacking, weight is a very important consideration, and I usually have very few gadgets on which I can use a really extensive toolkit. I find that the original PST (4-5 oz)works fine for these situations (I have carried a PST since 1985). I love the Wave(9 oz) for general wear, front or back country, when weight isn't all that critical. When bicycling I carry a small toolkit specific for the bike I am riding - either the Wave or PST is incorporated. If I am car camping or travelling by car, I carry about ten pounds of tools and basic replacement parts belts, etc). The Cruch is intriguing, but I have several smallish Vise Grips that are far less expensive than a Crunch, and that work well with a Wave when doing roadside work. I find that usually the tool I reach for to supplement whatever Leatherman I am using is a really good screwdriver and, after that, a socket set.
