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.
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 .

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.

Knapping freehand allows for greater control while supporting the core against the leg makes the work easier. The technique used to make the tranchet flake was used in the making of other tools as well, including tranchet axes (characterized by their trapezoidal or triangular shape) adzes, and even tranchet arrowheads. Unlike chisel arrowheads ...
