I believe the bow and arrow to be a perfect survival tool. Even though you can make your own gun powder you still have to have all 3 ingredients. For a bow and arrow, the components are all around most of us. Points can be made from found materials and objects. They are relatively easy to make and are quite effective.
Most of us will never have to deal with a survival situation but if push came to shove, I believe I could hold my own. I don't knap but if I had to I could make an assortment of stone tools...if we had decent rock here!
Today's society wants everything handed to them on a platter. The easy way out! The 8 guys that I have been hunting with for 25 years, all very good friends, consider me the "token" primitive guy. They all hunt with wheels and as soon as possible get the 270s, 30 06s and 308s out for the rest of the season. They just don't get it. None of them "need" the meat for survival, although they all enjoy it for dinner.
They think what I do is cool and each loves the "primitive" arrow hanging on their office wall... but they don't get it.
I have rim fire and center fire long and hand guns. I have a black powder gun. I have lots of bows and bow making materials, arrows and arrow making materials, I have knives and hatchets and steel and stone for blades and points, plants for cordage, glue and dyes and clay for pottery...if I need it! The road I am traveling is going towards simple but effective!
...but I, we, are of a different mindset than most. I think we would all use what we had available, in the order of its ease, to survive. Hopefully it will be use by choice and not necessity!...and until then, "I'll do it my way!"
