I carry a swisschamp too and find I use most of the tools on a weekly basis, with the exception of the corkscrew....

The hook has a slim nail file on the back, so it's not totally useless!

I've used the hook at a parcel carrier many times. Many year back when recycling newspapers, we would bundle up the piles with twine. That stuff would did into your hand when carrying it out. The hook/handle would make carrying the bundles out quite easy.

I have a Vic Rambler and use almost all the tools. The toothpick for its intended purpose. I've also used it as a probe which won't scratch most other things, and won't conduct electricity. The tweezers likewise, eg for pulling errant hairs.

The scissors work well on nails, and can also cut plastics etc - I often prefer them to a knife for safety. The file is also good for fingernails. Flat and Philips screwdriver are always useful in urban environments. The Philips is magnetised which I've used for picking up dropped screws or for keeping them on the end of the
driver while positioning them. (In a pinch it could be used to make a compass, if I researched which end was North first.) I also carry an LM Juice, and the scissors and Philips screwdriver on that are bigger but less useful.

The bottle-opener works but it's not great, and is really only a backup. I've not really used the wire-straightener.

I'm not sure I can say that I have an Every Day Carry, it fluctuates too much as I continually tweak it, but I do make a point of carrying something everyday and besides my keys and wallet I have some form of a swiss army knife too. Not a day goes by that I don't use it for a dozen things. I've even been known to carry the SwissChamp, usually on my belt, and have used every single blade on it.
