On today's show we try out a slightly different format. Dr. John Whittaker, professor and author of many books and papers on flintknapping and stone tool use, starts out the first segment with a lecture about the Atlatl - an ancient spear-throwing device. For the last two segments Chris and April ask Dr. Whittaker about the Atlatl, his experiences with the device, and the growing community of atlatl enthusiasts.
