As Jarad Diamond pointed out in the book "Collapse," the "stone age" was not one continuous, unchanging epoch. Stone tools evolved and improved radically in different parts of the world. The ones from later periods are much better than the early ones. Kyocera is a continuation of that development. We still build houses out of stone, too. - Jed
