I look at the EDC as a way to defend myself, take care of minor emergencies , the "nice to have" stuff and some capability for disaster. Defence is a Ka-Bar/Dozier folder and
B&K neck knife. Sometimes I add OC spray. Minor emergencies is migraine meds , a couple of knuckle band aids, a large band aid , antibiotic ointment, cortisone cream, betadyne wipe, alcohol wipe. Nice to have stuff is buttons needles, floss, backup $1.00 keychain light, whistle, SAK card, swiss tool, P-38, $1.00 mini strobe. Also carry a surefire light and SOG multi tool as well as cell phone, $ wallet and keys with the usual compass, Photon light, whistle. The EDC stuff fits into what is at work and what's in the mini van. So all together I could camp for a couple of days.
