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.
