flake toolStone Age devices, usually flint (see chert and flint), shaped by flaking off small particles or by breaking off a large flake to use as a tool. Prehistoric humans preferred flint and similar siliceous stones because of the ease with which they could be chipped and for their sharp cutting edges. They also used sandstones, quartzites, quartz, obsidian, and volcanic rocks. Stone tools were chipped by striking a block of flint with a hammer of stone, wood, or bone or by striking the block itself on the edge of a fixed stone. Pressure flaking consists of applying pressure by means of a pointed stick or bone near the edge of a flake or blade, to detach small flakes, and was used mostly to put the finishing touches on tools.

No references found | The easy-to-manufacture tools - also known as microliths - were a vast improvement over larger stone flake tools used previously, according to Michael Petraglia, an archaeologist at the University of Oxford, UK, who led the study. However, some experts suspect that the core tools were only byproducts of another type of tool: the flake tool. |
