Thanks everyone, I'm already sitting more comfortably than I have in a couple of months.
WW, +1 on the Leatherman Wave: It has the saw, can opener and I think the new one has a new and improved bit driver. Pliers work well, plus Leatherman will fix it free for the cost of outbound postage, IIRC. Mine went back once - one of the leaf springs broke and it had a ¼" gap when folded closed. Still an excellent tool, just the skeletool is lighter and all I need for work. Wave rides around in my murse and my paracord kit. As for Gerber, meh. I've had a couple, one is in our car glove box and never gets used, and the other I just got and will probably give to a "non-power user" for Christmas. I'd stick with Leatherman, IIWY.
