On serious days I have a leatherman surge, and I’ve used everything on it many times over, including the bit sets and swappable file/saw. I have a tiny AJ, a short Sharpie, and a little (importantly) gold inspection torch that all fit in the sheath/holster thing, along with a couple of lock picks and some wire.
On normal days I have a knife and a torch, and that gets me quite a long way
