Does the angle of your striking tool affect the flaking process?

Angle of Incidence

The angle of incidence is critical in percussion flintknapping. A striking angle of 30-40 degrees is generally considered optimal for removing large flakes, as it allows for maximum kinetic energy transfer to the core. However, more precise control is required for smaller flakes, where a striking angle of 20-30 degrees is often used to produce more delicate, controlled removals.

Angle of Strike and Flake Direction

The angle of strike also influences the direction of the flake removal. A vertical strike can produce flakes that are oriented in a plane parallel to the core, while a more glancing strike can produce flakes that are oriented in a plane perpendicular to the core. This understanding allows the flintknapper to control the direction of the flake removal, making it easier to create specific shapes and forms, such as arrowheads or blades.

Pressure Flaking and Angle Control

In pressure flaking, the angle of the striking tool is even more critical, as the force applied is gentle and controlled. A sharp, precision-edged striking tool is used to remove small flakes, often in a direction perpendicular to the core. The angle of the striking tool in pressure flaking is typically around 10-20 degrees, allowing for precise control and delicate removals.
