The ability to fabricate tools from native materials is always a good skill to possess. The worldview that such an individual is somehow superior to another using metal and plastic is not. I never met any 'native- traditional' who arbitrarily wandered naked into the California brush and as an afterthought wove a set of bluejeans and flip flops from chewed yucca stalks. Most of the traditional peoples I know think steel knives and bic lighters are pretty nice things to possess. Metallurgy is a very ancient, traditional skill. Oetsi didn't seem to have any qualms packing a copper axe. I am sure if he saw a contemporary Wetterling or Granfors Bruk it would be at the local full moon swap meet next to grandfather's polished stone axe. Tool assemblies are a preconceived concept in anticipation of a future event. This is called abstract thinking, one of the marks of human intelligence.
