The latest "pictures of things in our pockets aligned in neat rows" blog we've stumbled across is Everyday Carry, this one addressing people closer to MacGyver than the average Joe:
Everyday Carry, or EDC, generally refers to small items or gadgets worn, carried, or made available in pockets, holsters, or bags on a daily basis to manage common tasks or for use in unexpected situations or emergencies. In a broader sense, it is a lifestyle, discipline, or philosophy of preparedness.
Clicking through EDC you see a lot of stainless steel, multi-tools and things that can be used to kill other human beings, though those latter items are presumably carried in the name of self-defense. Guess we all have different definitions of what constitutes an emergency. In any case, it's a fascinating browse. Also makes me want to see what the everyday carry requirements would be for those prepared for an industrial design emergency.
