Here's How To... Make An Arrowhead

Flintknapping is the making of flaked or chipped stone tools. This technology was used in historic times to manufacture gun flints and in prehistoric times to make spear and dart points, arrow heads, knives, scrapers, blades, gravers, perforators, and many other tools.

Flintknapping requires the ability to control the way rocks break when they are struck. The best rock is somewhat brittle and uniform in texture and structure, lacking frost fractures, inclusions, or other flaws. This type of rock is very fine grained or non-grained. The best rocks for flint-knapping are chert, flint, chalcedony, quartzite, jasper, and obsidian. These rock types, when struck with another rock, piece of antler, or bone, will fracture or break in a characteristic pattern called a conchoidal fracture. This creates a rock fragment called a flake.

The production process begins with a piece of raw material, called a core. Flakes are removed by striking the edge of the core with a sharp, forceful blow, in what is called percussion flaking.
