A hammer has always been known as the king of tools. Over the last 100,000 years, there has been a natural evolution from using the clenched fist of an extended arm to a rock to a purpose-built striking implement. Grasping a tool in the hand or attaching it to a rudimentary handle creates endless potential applications when you consider the multiplication of force that is possible. The issue is only the material used in the construction of the striking portion and the expected results when using different natural materials. In this particular case, it is a form of stone.
