If you're really interested in this, the best place I've found is the "Everyday Carry Forums", where they talk about this all day long: http://edcforums.com/ http://edcforums.com/. Here's my list: In pockets: * Wallet. I looked around for a looong time for the perfect wallet, then I found these guys: http://www.all-ett.com/ http://www.all-ett.com/. I use one with leather lining, and it's an amazingly thin wallet, but which looks like a regular one. Has space for all my cards (not that many), plus some money. * Cellphone (Samsung Touch, a terrible phone I'm stuck with) * Keychain - An openable metal ring for easy removal of stuff, which right now include: Car keys, house keys, 8gb flash disk, and an old CPLD chip from my former job with a hole in the middle. In back pockets: * Coins, rarely. I almost never keep coins on me, but sometimes you get stuck with them after cash transactions (I prefer credit cards any chance I can use them). * Extra keys, if I need (taking a different car than my regular one, etc.). Used to have or want: * Used to carry a small LED flashlight (don't remember which), but it lost its battery and hasn't been replaced (sadly). * Wish I had a small pen. * Have a Leatherman Squirt pocket everything, but don't usually carry it around.
