Precut stone is a DFMA construction method that uses large machine-cut stone blocks with precisely defined dimensions to rapidly assemble buildings in which stone is used as a major or the primary load-bearing material. Massive precut stone construction was originally developed by Fernand Pouillon in the postwar period. He referred to the ...
Stone has been used to make a wide variety of tools throughout history, including arrowheads, spearheads, hand axes, and querns. Knapped stone tools are nearly ubiquitous in pre-metal-using societies because they are easily manufactured, the tool stone raw material is usually plentiful, and they are easy to transport and sharpen.

The Kilmartin Stones in Scotland - a collection of ancient stone carved graveslabs Khazneh structure carved into a cliff in Petra southern Jordan.

The flakes are shaped using the lithic reduction techniques, allowing for creation of various tools such as arrowheads and handaxes. Two stone characteristics will determine whether one is able to chip away large enough flakes to make tools out of: whether the stone is of a cryptocrystalline structure, and how conchoidally the stone fractures ...
The Levallois technique (IPA:) is a name given by archaeologists to a distinctive type of stone knapping developed around 250,000 to 400,000 [1] years ago during the Middle Palaeolithic period. It is part of the Mousterian stone tool industry, and was used by the Neanderthals in Europe and by modern humans in other regions such as the Levant. [2]
Soft hammer techniques allow a knapper to shape a stone into many different kinds of cutting, scraping, and projectile tools. These "soft hammer" techniques also produce longer, thinner flakes, potentially allowing for material conservation or a lighter lithic tool kit to be carried by mobile societies. [2]
Ancient stone tools found in western Ukraine may be the oldest known evidence of early human presence in Europe, according to research published Wednesday in the journal Nature. The chipped stones ...
The enormous geographic spread of Acheulean techniques also makes the name unwieldy as it represents numerous regional variations on a similar theme. The term Acheulean does not represent a common culture in the modern sense, rather it is a basic method for making stone tools that was shared across much of the Old World. [citation needed]
