Most used- Scissors and bottle opener for me, but I will say, I lost the toothpick once, and didn't realize how much I needed it until it was gone!

The tweezers are wimpy, but I did use them to snag a pill I had dropped just out of finger tip reach between the seats of my car, and on another occassion to pull a lace through a punched hole.

I actually went to the Victorinox site to try and figure out what the hook was for- they just call it the "universal hook". But I did find it also referred to as "parcel carrier" and "safety box cutter"..............
