Flint is usually dark grey, blue, black, or deep brown in colour. It occurs chiefly as nodules and masses in chalks and limestones.

Along with chert, this mineral was one of the most commonly used materials for the manufacture of stone tools during the Stone Age, as it splits into thin, sharp splinters called flakes or blades (depending in the shape) when struck by another hard object (such as a hammerstoneIn archaeology, a hammerstone is a hard cobble used to strike lithic flakes off a lump of tool stone during the process of lithic reduction. Often, a hammerstone is made of a material such as limestone or quartzite, is ovoid in shape (to better fit the hu made of another material).

Flint mining is attested since the Palaeolithic, but became more common since the Neolithic ( Michelsberg culture , Funnelbeaker culture).
