I'm not very creative and just keep my everyday-carry picks in my pocket, on a keyring made from stainless steel cable.
They're just my emergency tools for when I run across unforeseen situations. I have a nicer and more comprehensive set of entry tools for on-the-job use, or when I KNOW I'm going to have to open something.

This old picture is sort of version 1.0 of the concept and it's been changed a lot over the years since I took this pic.
The first change is that I replaced that old fiberglass handled Southord jackknife seen in the picture after trying out the aluminum handled folding pickset from Southern Specialties and found it to be of almost infinitely better quality and usefulness than the Southord. Several of the jigglers shown there had already been altered as of the time of that picture, one of them into a key for certain types of restraints. I've modified a couple others since that then and removed most of the rest from the ring since they're mostly just dead weight.
I've added small pliers and folding screwdrivers, a tiny LED flashlight, several different bypass tools and even a small prybar which works pretty well despite it's diminutive size. The first prybar was carbon steel but was prone to rust spots because of sweat while in my pocket in the summer, so it's been upgraded to a titanium version of the same tool, which also lightened things up a bit.
Basically, this set is always in flux: adding things as I run across situations and discover a new need, then removing things that might have sounded good at the time but I haven't had to use in ages. I carry it with an elastic strap around it which pads the sharp corners and keeps them from jingling.
