Stone Age
Stone tool flaked on one surface only, known as a uniface blade, and three end scrapers.
Flint was the preferred material for toolmaking during the Stone Age primarily due to its physical properties and workability. As a homogeneous and isotropic material, it possesses equal properties in all directions, which allows it to be shaped predictably.1
Key reasons for its value include:
- Fracture Characteristics: Flint displays a conchoidal, or shell-like, fracture. Because it lacks cleavage planes, it breaks in a controlled manner when struck, consistently producing extremely sharp cutting edges.12
- Ease of Shaping: It is relatively easy to chip using both percussion and pressure flaking methods, allowing prehistoric humans to create a variety of specialized tools.2
- Hardness: Flint is harder than most steels, making it durable enough to serve as an effective tool for working other tough materials like wood, bone, and antler.31
Due to these advantages, flint was widely sought after and became a significant object of trade, with specialized mines established during the Neolithic Period.1
