Microlith

A microlith is a small stone tool usually made of flint or chert and typically a centimetre or so in length and half a centimetre wide. It is produced from either a small blade (microblade) or a larger blade-like piece of flint by abrupt or truncated retouching, which leaves a very typical piece of waste, called a microburin. The microliths themselves are sufficiently worked so as to be distinguishable from workshop waste or accidents.
