Wow!

I've carried a SAK for over over 35 years, and it is my most used tool:
screwdriver, both Phillips and flat blade (anything needing a screwdriver---lots of things)
Large Blade (Blister packs, mostly, also cut up a lot of Apples, anything that needs to be cut, etc.)
Small Blade (smaller packages, cut small things)
Can Opener: Lunch, cans
Bottle opener: Lunch, bottles
Awl: punching holes in things
Toothpick & Tweezers: their intended functions..

too many times to remember. . .

It is never quite the best tool for the situation, but it always gets the job done for me. . .
