What Type of Hammerstone Works Best for Flaking?

Choosing the Right Hammerstone

When selecting a hammerstone, look for one with a rounded or oval shape and a flat striking surface. This shape allows for a controlled impact and helps to minimize damage to the flaked edge. A hammerstone with a flat striking surface also provides a larger surface area for striking, which is essential for generating the force needed to flake a stone tool.

Preparing the Hammerstone

Before using the hammerstone, it’s essential to prepare it for flaking. Take the hammerstone and strike it gently against a hard surface several times to create a flat striking surface. This process is called “flattening” the hammerstone and helps to remove any sharp edges or burrs that may interfere with the flaking process. A hammerstone should be flattened to a thickness of about 1/4 inch (6 mm) to ensure a smooth striking surface.

Techniques for Effective Flaking

To effectively flake a stone tool using a hammerstone, follow these techniques: Hold the hammerstone with a firm grip, but not too tightly, and strike the stone tool with moderate force at a 45-degree angle. Aim for the center of the stone tool, and strike it with a smooth, glancing blow. Repeat this process several times, moving the hammerstone around the stone tool as needed to create the desired edge or shape. By following these techniques and using a properly prepared hammerstone, you can create high-quality stone tools through percussion flaking.
