Stone tools are the most ancient evidence of our ancestor's ingenuity, proof that we've been augmenting our bodies for millions of years. These flint tools by Ami Drach and Dov Ganchrow update our prehistory with modern materials and techniques. Each knapped tool is scanned and then outfitted with a form-fitting 3D-printed handle. In marrying the most basic fabrication technique with one of the most advanced, Drach and Ganchrow's project demonstrates how modern technologies return us to the tribe. Via Design Boom.
