What does the term "percussion flaking" refer to in flintknapping?

The term "percussion flaking" specifically refers to a technique used in flintknapping where a hard hammer is employed to strike a stone core, leading to the detachment of flakes. This method is fundamental in the production of stone tools, allowing for the controlled creation of sharp edges and specific shapes. By striking the core at strategic angles, artisans can remove flakes that are essential for crafting tools like arrowheads or cutting implements. This technique contrasts with other methods that may involve grinding or polishing, which are not designated as percussion flaking. This understanding of percussion flaking emphasizes its role in early human tool-making practices, showcasing how mastering such techniques was crucial for survival and functionality in prehistoric societies.
