Okay, so for the bare minimum EDC that you'd have pretty much anywhere except the security line of the airport, I figure my Leatherman or SAK, an LED pocket flashlight, and my butane lighter. This would keep me from eating crow in most all situations I might have need of survival gear. In fact, it is what I EDC 16-20 hours a day anyways. Along with my cell-phone, wallet, and keys, and money when the girls haven't picked my pockets, that's about it for full time EDC. Next would come the Glock, but I think that is too specialized for most. Well, maybe not the folks here, but in general pop for sure.
