Using everyday is what EDC stuff is for. The backpack I carry every day would make a great wilderness survival kit, but it's an EDC kit, everything there is available for use all the time. I'm moving away from "kits", little containers of stuff I forget about and going toward EDC user stuff. Situationally, the stuff may change; my EDC backpack has a lot of gear that would go in my pockets in a real situation. I think there's a DR PSP buried in the bottom next to a small FAK.
