There's a big overlap between EDC and PSK, if you do it right. The trick is to find survival tools that you can use every day, that way you have an incentive to always keep it with you. Then it will be there for a survival situation. That's what I like about a keychain survival kit. Even if some of the items on the chain aren't used every day, something on the chain is always useful, so it's always in your pocket.
