Groo,

That's exactly what I've done. I actually carry two wallets - a slim "L.A. Wallet" from County Comm holds my credit cards, driver's license, registration, and my traditional wallet has money, safety pins, duct tape, needle and thread, masons' twine, a mini ferro rod, tinder tab, piece of hacksaw blade, fresnel lens, space pen refill, 2 small Rite in the Rain sheets, County Comm straight razor, and a cheapy garbage bag. I had to move the credit cards in order to cram this stuff in the wallet. I also EDC a P4 Squirt, a Swissmemory knife, a Ritter RSK, whistle, and a County Comm led light. This is about as bare minimum that I'm willing to go for suburban EDC.
