I have a small "kit" in the pocket of my SpecOps Navigator sheath. It includes: Gatco Triseps sharpening stone, Silva Starter compass, LMF swedish fire steel, Streamlight Nano flashlight, Bic lighter, Katadyn water purification tablets (four tablets in factory blister packaging).
I've wrapped 550 7-strand paracord around the outside of the sheath.
This isn't an EDC setup though - its a super lightweight "woods walking" rig.
With this kit I can:
* Make Fire
* Make Shelter
* Purify Water
* Navigate (even at night)
* Signal For Help (not that manly men need to do this <img src="/ubbthreads/images/graemlins/doh.gif" alt="" /> )
