flake tool, Stone Age hand tools, usually flint, shaped by flaking off small particles, or by breaking off a large flake which was then used as the tool.
What is a flake rock?
Chert and flint are silica-rich rocks found throughout the Midwest in limestone and dolomite deposits. These rock types, when struck with another rock, piece of antler, or bone, will fracture or break in a characteristic pattern called a conchoidal fracture.

Flaking produced by natural causes is usually haphazard, and fractures by frost or heat are characterized by a series of concentric rings as opposed to the ripple marks left by a man-made fracture. Stone tools were chipped by two principal methods: percussion and pressure.
How are flatflake tools made?
Flake tools are created through flint knapping, a process of producing stone tools using lithic reduction. Lithic reduction is the removal of a lithic flake from a larger stone in order to reach the desired tool shape and size. The beginning stone is called the flake lithic core. There are three steps to lithic reduction:
