Bamboo has some natural aspects that are great for MANY primitive skills. The hollow middle and segregated growths make for great primitive tea straining straws, also called bombillas. simply cut below node on top of straw and just under node on bottom, leaving a closed end. poke or drill tiny holes all around bottom end of straw, acting as a strainer. you can then use this straw to drink unfiltered coffee or tea!
i also use bamboo for my bow drill bows. i cut a piece that is just stout enough to not bend easily, but enough to give a little, remove all shoots from it except those on very top and bottom of bow. i make the bow as long as my fingertips to my elbow. the small pieces of shoots i leave on act as great anchors for the ends of my cordage. i then take a piece of old leather, cut it in a spiral fashion, twist into single ply twist cordage and voila, amazing light weight and durable friction fire bow!, i also wrap excess leather on handle end of my bow to create a leather ended drum mallet.
you can also make friction fire in the form of a fire saw with bamboo!
jsut cut a bnch down, store it in an upright stance for a couple months while it dries. once it is golden in color you're ready to rock!
