My first "survival" knife was a good old Boyscout BSA pocket knife.
It saw a lot of use on youth camping expeditions, whittling, making tinder, and opening cans of pork&beans.
Next, for a dumb idea, was the good old, dull-arsed original AirForce Survival knife.
I was still young, didn't know how to re-profile a blade, and to this day I believe the purpose of that old original 1950's design was to give AF pilots something to do while waiting to be rescued, namely, try to put an edge on the dull blade with what appeared to be a soft "sand stone".

Needless to say, the Boyscout knife didn't leave my side.
in the 1980's the "Survivalist movement" went mainstream, and so did all of those hollow handle survival "Rambo" knives. Never got one. Oh yes, I longed for one, looked at pictures, drooled, but only wanted the "expensive" one, over $100 USD, and never made the purchase.
Instead of going "Rambo", and without a lot of thought, I purchased my first SAK. My dad had one, but I didn't have one of my very own. Back then I didn't know one model from the next, I simply pointed under the glass and said, "I'll take that one!". Purely an impulse buy, wow, best impulse buy I ever made. It was similar to the "Camper" model. A mid size, I guess is a good term for it.
The Air force "survival knife" became a garden trowel, the Boyscout knife went into the sock drawer. That SAK was thee "do all" camping tool for me, for years.
The other "great" purchase, was my Ontario Machete, also back in the 1980's.
So, removing the Boyscout pocket knife from the equation, my first "tried and true" Survival set-up was my SAK in combo with my trusty mil-spec Ontario Machete.
The machete could handle chopping good sized limbs, split firewood and clear trails. The SAK cut small tinder, opened cans and bottles, cleaned fish, wittled, sliced tomatoes, and all those other little camp chores.
With my Machete and trusty SAK I could "hang" with the best of them. :thumbup:
