Denticulated tools have a serrated edge consisting of two or more shallow notches. The notches are usually not that deep, demonstrating that they were likely made with “pressure flaking,” wherein flakes are removed by firmly and continuously pushing a sharp instrument against the stone, rather than by repeatedly striking it. The notches were retouched several times to create the grooved blades. The side of the tool opposite the blade was relatively blunt, so that it could be held by hand or attached to a wooden base.
