Knapping is the shaping of flint, chert, obsidian, or other conchoidal fracturing stone through the process of lithic reduction to manufacture stone tools, strikers for flintlock firearms, or to produce flat-faced stones for building or facing walls, and flushwork decoration.

A flint flake tool from the Neolithic, found in Hertfordshire, England. In archaeology, a flake tool is a type of stone tool that was used during the Stone Age that was created by striking a flake from a prepared stone core. People during prehistoric times often preferred these flake tools as compared to other tools because these tools were ...
The prepared-core technique is a means of producing stone tools by first preparing common stone cores into shapes that lend themselves to knapping off flakes that closely resemble the desired tool and require only minor touch-ups to be usable.
Knapped stone tools are made from cryptocrystalline materials such as chert, flint, radiolarite, chalcedony, obsidian, basalt, and quartzite via a splitting process known as lithic reduction. One simple form of reduction is to strike stone flakes from a nucleus (core) of material using a hammerstone or similar hard hammer fabricator.
