I EDC a SAK. I would say that I've used everything on it.

-Small blade typicall for opening packages.
-Large blade for normal knife/cutting uses.
-Scissors for cutting thread / paper / trimming.
-Can opener for intended purpose (someone had a pop top can that failed to open and I was able to open it using this)
-Large / small screwdriver
-Bottle opening for many a beer
-Corkscrew for many a bottle of wine
-Awl for cleaning fingernails / punch / awl work
-Hook for carrying bundles. Keeps thin straps from cutting in my hand.
-Tweezers for small splinters
-Toothpick as intended.
