I have two tools, a LM Charge TTi and a SOG Powerlock. I bought the TTI mainly for hiking and such, as well as making the occasional trip to work (when I want to bring something more robust than a SAK Soldier with me). I've used it for:
- stripping bark and cutting off knots off a walking stick
- phillips bit for the Tech Lock for my RAT 3
- can opener for obvious purposes when my normal one crapped out a few months back
-flathead screwdriver for lifting stuff (paint can lids)
- Scissors for....cutting things
- Stirring tea or soup in a thurmos with the pe blade
Strangely enough, I've never really used the blades for their intended purpose. I usually carry my RAT 3 (or a Buck 105, but I usually don't like something that big) if I need a knife to cut something with.
The PowerLock. I bought this beast solely to have it in my car. I absolutely adore the pliers on this thing, as well as the exceedingly sturdy construction and its customizable nature. The downside? Everything clumps like a mofo, I can't reach smaller tools easily enough, and the edge of the saw/blade face the inside of the handle if I ever need to use them, meaning I would have to hold the tool at an angle or something. Other than those gripes, I haven't really used it alot, and it's really just there for emergencies.
I also have more SAKs than I know what to do with, but I've been bitten by the collecting bug.
