I am always surprised at how much I actually use my Leatherman Wave, so I always recommend it for briefcase or pouch carry in an EDC rig. I also have a SOG Crossgrip and a Swisstech Utilikey as a backup. Probably a little much. Plus yet another Utilikey and the allen wrenches for my Sebenza and TID-mounted Surefire E2E.

I really like the design of the SOG powerplier tools, but they are not as comprehensive as the Wave. My "doomsday" (as in earthquake or similar) kit has an Emerson Mini CQC7A and a SOG Mini Deluxe Power Plier. Unlike the Wave and the Sebenza, they can be maintained with ordinary tools. All the electrics (radio, flashlights) in the doomsday kit run on AA batteries.
