This isn't really a guess -- it's more in the line of a suggestion. <img src="/images/graemlins/smile.gif" alt="" />

Have you ever considered putting together an Urban PSK? Although urban dwellers don't need firestarters & fishing line (generally speaking), we do have our own set of needs. It would also have an infinitely (well, for some definition of infinite) larger potential audience, given that crazy post-industrial tendency for people to live in cities. I'm thinking of something with no blades, so it's acceptable in secure office buildings, courthouses, etc. (Perhaps it could even avoid the ire of the TSA?)

Contents might include:

1) Bladeless multitool
2) N95 particle mask
3) LED light
4) CPR mask
5) Basic meds
6) Basic bandages
7) Parachute cord
8) Whistle
9) Mini glowstick
10) Basic instructions, including how to get out of a trapped elevator

I'm thinking of something small enough to fit in a pant pocket, so it's always available.
