I thought this an interesting concept. Check it out: Tools and designer gifts for urban survival

These are basically, and I quote, "credit-card-sized urban survival tools made from 316 stainless steel." Don't know how practical they would be in actual use, but they sound and look cool enough.

I like the "Clearway" Ice Scraper, "Emergency SOS" Medical ID Tag, and Fire Starter Match Box the most.
