Those Baggu bags are awesome. My favorite one (of mine, not of theirs) folds up into a little elastic drawstring holder that looks like a tiny slice of watermelon. It's adorable.

The thing about my Leatherman choice is that I have never let go of the idea that I might have to strip wires at any moment. (Now! Or now! It might happen!) So I am possibly the wrong person to ask which model is Really Useful. (Or now!)

I only have a dumbphone, which is somewhat less useful as a flashlight.
