am beginning to develop a fair collection of these things, and I'm working on a set of opinions to go with them.
In descending order:
1. Leatherman Wave - Good solid machine, it isn't perfect, but it does what I need most with the least fuss.
2. Leatherman Crunch - Excellent locking plier. Very useful, very compact. Phillips screw driver seems to fit everything regardless of size. Knife blade and file are marginal, better than nothing but not by that much.
3. Leatherman PST - Spyderwrench - Tied for third. The PST does everything pretty well, nothing extra, very compact. Spyderwrench has some great features including adjustable wrench, very serviceable knife blade and interchangeable bits. Great gadget factor. Too many lose parts, often Too hard/slow to get into action.
4. Leatherman Sideclip - really very good for a minimalist tool. I'd like to trade the knife blade on this one for something else, maybe a file or hacksaw blade.
5. Kershaw locking plier - spare parts are available, file blade and hacksaw blade can be replaced when worn. Knife blade is accessible one handed with tool closed. Nice open top belt pouch with clip rather than belt loop. Needle nose pliers are light duty only, they will withstand little or no side torque Tool seems over bulky especially in view of light duty pliers.
6. Bucktool - solidly in last place. It's hard to think of anything nice to say about this thing. The little pictures engraved on the handle to show you where the different tools are is a nice idea. The tools lock open, but what difference does it make when the handles fold up during use. Maybe it's just me being left handed. There is a lot of flex in the handles, they can be bent into full contact with each other with moderate hand pressure. Anything more than moderate hand pressure and the handles start to fold up. My bucktool is an early production tool, I have heard that improvements have been made but I am unclear as to what these improvements are.
