Microliths are made of chert or flint and are no longer than one centimeter or half a centimeter wide. It is made from either a small blade or a sharp piece of flint through what is known as retouching, or resharpening. They have been worked enough to be easily distinguishable from workshop waste.
Types[]
There are dozens of varieties, varying definitely by region and probably by specific use. Some appear to look like mini-arrowheads, while others have a long bladed edge. Many are symmetrical, while others are not.
Uses[]
There are many ideas about the uses of microliths, but it is clear they were primarily a hunter's tool. Microliths were probably used to increase the penetration power of weapons. For that purpose, they might be attached to the back end of a spearhead, arrowhead, or harpoon. It could be argued that Kediak's mace is an example of the use of obsidian microliths.
