"is it cool to know how to make fire with a bow drill? Yes - but survival is not about proving that you're some kind of earth skills guru; its about dedicating your energies to getting homesafetly or getting rescued"
As Les has said above being able to bow drill is good (its a well rounded knowledge thats needed) but being able to light a fire first time every time is more important.
And this has made me think - being able to carve a spoon is a good skill but isnt carrying a metal spoon better??
Being able to make roycroft rucksack frame is good but should we replace our karrimor with one?
We shouldnt replace knowledge with kit of course - but that doesnt mean we go without kit thats useful and in some ways superior!
Something to ponder next time you look at kit old and new!!
