The diagram below shows the development of cutting tools in the Stone Age.
The diagram illustrates how the cutting instruments used during the Stone Age evolved between 1.4
million and 0.8 million years ago.Overall, it is clear that Tool B is sharper and more regularly shaped than the earlier Tool A. Over a period of 0.6 million years, the cutting tool also increased in size and effectiveness.
The front view shows that the edges of Tool A are rough, revealing its more earlier stage of
development. Whereas Tool A is comparatively primitive, therefore, the smooth edges of Tool B are clearly more effective as a cutting instrument.
One of the main differences between the tools is shown in the side view diagram. While Tool A is
irregular, in contrast Tool B has a regular, flattened shape. The sharp edge of Tool B is designed for
cutting objects cleanly and easily. Finally, the back view shows most clearly that Tool A is not only
rougher, but is also smaller than Tool B.
