Throughout history, Tool stone has played a fundamental role in various aspects of society, from its influence on culture and art to its impact on science and technology. Through a comprehensive analysis, we will examine the different perspectives and discussions surrounding Tool stone, seeking to shed light on its implications and possible future developments. Likewise, we will consider the opinions of experts in the field and take into account the experiences and testimonies of those who have closely experienced the influence of Tool stone in their lives.
In archaeology, a tool stone is a type of stone that is used to manufacture stone tools, or tools that use stone as raw material.
Generally speaking, tools that require a sharp edge are made using cryptocrystalline materials that fracture in an easily controlled conchoidal manner. Cryptocrystalline tool stones include flint and chert, which are fine-grained sedimentary materials; rhyolite and felsite, which are 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.
Large-grained materials such as basalt, granite and sandstone may also be used as tool stones, but for a very different purpose: they are ideal for ground stone artifacts. Whereas cryptocrystalline materials are most useful for killing and processing animals, large-grained materials are usually used for processing plant matter. Their rough faces often make excellent surfaces for grinding plant seeds. With much effort, some large-grained stones may be ground down into awls, adzes, and axes.
