24. burins
According to Merriam-Webster dictionary, burins are prehistoric flint tools with a beveled point. A hominid species preceding homo Sapiens named Aurignacians were a very large turning point in the advancement of stone tools, known for inventing the burin. A burin is a tool used for engraving antlers and other kinds of bones, containing a tiny point that allowed for more detailed work. This tool consists of a metal rod angled down in a diagonal line and flat handle with a rounded end so that the fingers of your hand can easily grasp and hold it. How the engravings that the burin produces are shaped and proportioned depend on the angle of the burin's tip.
