Grinding stones were used to grind and crush different materials including seeds, bulbs, berries, insects, fibres, and ochre. In hand-grinding, the top stone was small enough to fit in the hand, and usually had a convex surface. The bottom stone was usually concave, and the concavity developed as the stone wore away through use.
Capuchin monkeys (Sapajus libidinosus) in Brazil also use stone tools to crack nuts; researchers have discovered nut-cracking stones used by capuchins up to 3,000 years ago.

Pressure flaking is the last step in making the stone tool. Very small, thin flakes are carefully removed from around the margins of the tool by applying pressure with an antler tine. This type of flaking strengthens, straightens and sharpens the cutting edges of the tool and shapes the piece into its final form. Hafting spears.
