Here in Arizona you find lots of Quartz, everywhere. i was visiting my grandma, and i forgot my knife and she has 40 acres of nice desert property. so i took 2 large pieces of quartz and "bashed them together" and was rewarded with a fairly large arrow head shaped chunk of quartz. i chipped it down some more to get the "blade" thinner and i carved my self a walking stick. Would of been much easier to use a saw or something but hey why not.
