  4. Making stone tools The earliest technique is called stone-on-stone, where a large stone was used as a hammer to hit a smaller stone called the core. The core was the stone that was used to create the tool. And it was flaked till it had the shape of the tool. The second technique is called pressure flaking, in which the core is placed on a firm surface. Then, a piece of bone or stone tied to a wooden handle is used to flake the core and make the tool.
