Microliths are very small stone artifacts usually made from sections of small blades. They were too small to be used by themselves and would have been set into wooden or bone handles to make composite tools, some of which have been found. (Whittaker 1994. 37)
Microliths are often made on blanks produced by the micro-burin technique. Though microlith is often used for any small retouched tool a more strict definition is that the bulb of percussion was removed i.e. the microlith was made on a section of a blade/bladelet, and that at least two adjacent edges should be retouched. For geometric microliths this means that the shape was deliberately made into a geometric shape. Otherwise naturally tapering blades that are retouched may be classified as triangular microliths, when the triangular shape is merely fortuitous.
