The diagram below shows the development of cutting tools in the Stone Age.
The diagram provides a comparative overview of cutting tools that were improved in the stone age; precisely back to 1.4 million years ago and 0.8 million years ago.
In general, there is only one item from different perspectives, which has 5 cm in length for both categories. The device in 1.4 million years ago has more softened structure compared to that in 0.8 million years ago. Substantially, the tool has got a wider flattened surface with more tough edges in the later periods. Particularly in vertical view, the item is observed to be significantly slim when it comes to design in a period of 0.8 million years ago. Back to 1.4 million years ago, the cutting device has less pointed apex than that in the 0.8 million years later.
To sum up, there is an obvious alternation in the design of the cutting tool during the provided periods albeit the length is the same. These changes are the width of the surface, the pointed apex, and more or less edged in overall appearance.
