historical anecdote... I was lucky to have a pair of excellent Scoutmasters in the late 50's early 60's... one was a Marine combat vet from Guadalcanal on in the Pacific, and the other an OSS officer in the Balkans...our troop was pretty poor, so made do with surplus GI items... our "survival" rig consisted of a web pistol belt, stainless canteen, cup and cover, and a first aid pouch that held a Cutter snake bite kit (now not recommended), a match safe with nail polish coated kitchen matches, couple of pieces of lighter pine (what we called fat wood), single edged razor blade, bottle of tincture of iodine for water treatment and cuts, 25' of heavy braided fishing line, a dime for phone call, roll of friction tape, and a small piece of flint/chert for fire starting....a Scout or GI pocket knife on a lanyard if we could afford it... looking back, not too shabby for the time
