Answer:Flint knife
Flint is a hard sedimentary rock, occurring naturally in nodules and masses within softer sedimentary rocks such as limestones and chalks, where it is probably formed by geologic compression. Flint was used in the manufacture of tools and weapons during the Stone Age, as it splits readily into thin, sharp splinters called flakes or blades (depending on the shape) when struck by another hard object (such as a “hammerstone” made of another material). This process is referred to as knapping. Knapping is the shaping of flint, chert, obsidian, and similar types of stone through the process of “lithic reduction” –
a technical term for the controlled fracturing of the stone, followed by the careful, systematic removal of excess material to create a desired form and provide it with one or more cutting edges.
The specific characteristics of each piece of flint help determine what objects can be produced from it, so to a certain degree the stone itself dictates the precise form each object made from it will take. Methods of working flint and similar stones for making weapons and tools are among the earliest technologies developed by prehistoric humans. Flintknapping was probably among the earliest specialized work activities, as it requires a high level of skill and training.
