A comment from the article - "the art of survival hasn't changed much in 50 years." - basically a true statement, and probably pretty conservative at that. It wasn't a whole lot different when your flintlock was a multipurpose item - useful for starting a fire as well as ringing down game.

I wonder why they specified 188 lb breaking strength Kevlar line? It is strong and light, but I understand Kevlar is tricky to tie knots in. I would be happy with plain old nylon mason's line for most uses....
