A guy by the name of Tom Brown ? I believe is teaching it very well with a understanding that all one needs is provided by nature and the only tool one needs is the one between yer ears.
The one good point in this thread that all should understand is that if it is not on your person 24/7 when away from home it's no good. Your "kit" should be so small and comfortable that it's easily carried in a pocket.
My personal survival kit (PSK) is composed of the following.......
Leatherman Wave tool
Zirconium lil sparky bar from done rite mfg, covered in shrink wrap tubing
A 2 inch sewing needle with a large eye, magnetized and waxed
A small vial of potassium permaganate crystals for topical infection treatment and water purification
2 reynolds oven bags, large, for water carriers w/ 4 small wire ties as closures.
30 feet of sterile waxed dental floss
3 small dry flys & 3 small long shanked fishhooks w/ split shot attached
4 individually wrapped Life Boat matches
A flat ACR brand rescue whistle
A photon III white LED light
A 3M Mylar space "bag" vacummed down to the size of 6 or 7 playing card
A old AOL CD that I cut down to credit card size and drilled a hole in the center to use as an emergency signal mirror.
a 2x2 sheet of heavy duty aluminum foil.
A single edged razor blade (waxed to prevent rust)
All this is compressed in my food saver vacum kitchen appliance and then trimmed down to be carried in a small nylon wallet . The little wallet is about the zize of a deck of playing cards when packed in such a manner. I have made a lanyard from 550 para cord that I braided and added a small mueller clip to keep it attached to a belt loop or jacket pocket when I skydive, hike,fish, hunt or ride my ATV's.
Albeit I don't smoke I also keep a small bic lighter on me carried loose in my pocket. My Key chain has a house key and common single key for both my vehicles, a small Victorinox brand swiss army knife that has a small led light built into it and a second zirconium sparking bar with a small sewing needle with a hundred dollar bill wrapped around it just in case I lose the wallet with all my money . All that is secured with electrical shrink tubing and attached to my key ring.
Add this to my surefire E2 light with a TID device, my 1911A1 with 2 spare 10 round magazines and a terzoula ACTF knife. A S&W Model 317 snub .22 revolver with 50 spare rounds in an ankle rig as a backup and I go about my life in the urban jungle just fine.
A good idea for those that live in rural areas like I do is to have a triad concept that keeps a personal small kit on you 24/7....one carried in your vehicle in a day pack in case ya have to walk out from a bad session of 4 wheeling and your home. To build such for your home I will suggest you get up now , walk out to your power and water main and turn it off. Make a list all weekend long as to what you can and can not do and build from that......checking into the local holiday inn doesn't count !
Stay Safe Joe !!
