Tool stone
In archaeology, a tool stone is a type of stone that is used to manufacture stone tools,[1] or tools that use stone as raw material.[2]
Generally speaking, tools that require a sharp edge are made using
cryptocrystalline materials that fracture in an easily controlled conchoidal manner.[1]
Cryptocrystalline tool stones include igneous flowstones; and obsidian, a form of natural glass created by igneous processes. These materials fracture in a predictable fashion, and are easily resharpened. For more information on this subject, see lithic reduction
