Well, I do have a credit card size multitool that works well enough with a flint. I only recently added a few other components in a little bag, but I didn't really think it through. I just picked a few items from the lists and tried to fit in as much stuff as possible.
See
EDC thread for a list of my current items I'll probably drop the Stanley blade, safety pin, saw blade and add a compass. I'll experiment with the flashlight bezel part and see how that could be utilized. I'm pretty sure there is a way to fit in both a Micropur pill and a painkiller in that bezel somehow.
I bought some hot laminate pouches today.. I'll convert that anti-static bag with it's contents into a more rigid sealed plastic package that should also be more water proof and perhaps a bit thinner too.
