Last Monday, the Heritage Crew got a lesson in lithics from the Archaeology department at the Science Museum. Lithics are stone tools like arrowheads, hammerstones, metates (millstones or grinders), and stone blades. Lithics,(or stone tools) come in many different shapes and sizes. Some stone tools are "unifacial" which means that they have been flaked on one side only. Others are "bifacial" which means that they have been flaked on both sides of the rock. There are some stone tools that can be "nonfacial" which means that they were not worked on and just used how they were. Efficient knappers (stone tool makers) can flake off long, thin blades and not have to rework it, and then would be able to haft the blade onto a wood or bone handle. Hammerstones however, were not worked on, they were just stones used to hit and crush objects. They were used in conjunction with anvilstones and usually had spots worn away and made very bumpy.
