Tool stone - In archaeology, a tool stone is a type of stone that is used to manufacture stone tools. Generally speaking, tools that require a sharp edge are made using cryptocrystalline materials that fracture in an easily-controlled conchoidal manner.

Ground stone - In archaeology, ground stone is a category of stone tool formed by the grinding of a coarse-grained tool stone, either purposefully or incidentally. Ground stone tools are usually made of basalt, rhyolite, granite, or other macrocrystalline igneous stones whose coarse structure makes them ideal for grinding other materials, including plants and other stones.
