Russ,

Well, they came in a pack of two at Costco. Rather than buy something else, I figured I'd put one in my bag.

Truth is, I've not been impressed with the things, and will probably be replacing them soon. I've had them for about a year, and they no longer hold a charge for the light. You need to keep turning the handle to get the light to work.

I don't think I'll be buying a new SAK for my bag, but I've toyed with the idea of tossing my Leatherman Charge Ti in the bag, however it was an anniversary gift from my wife, and I'm a bit scared I'll lose it
