I was browsing a very informative website lately and something really struck me. It read this :

Do not buy or assemble an "Emergency Kit" - carry the personal "Ten Essential Systems" in a day pack!"

Reading this was very liberating for me in a way that I always seem to struggle to "containerize" my stuff, and this advice really made sense to me. Everytime I go camping, fishing or on SAR assignments, I always carry some kind of backpack. So instead of focusing on micromanaging my gear ("Okay, this Photon goes in the FAK.. no, wait, i'll put it in my survival kit... or maybe tied to my OHT's keyring?"), i've tried seeing it in a more global way and it appears to be working well. Everytime I use one of my packs, I grab what I consider my essentials and throw everything in the pack.

A bonus is that I don't have excessive redundancy in gear. As an example, I used to have a small knife in my survival kit, and a small Victorinox Classic in my FAK. Now I basically ask myself "I need a tool to perform various cutting tasks" and I select my tool accordingly. If i'm going deep in the backcountry, i'll bring my Bahco saw along ("various cutting tasks").

I don't know if what i'm saying make sense to anybody, but if you're in my situation, you might enjoy this advice and want to give it a try!
