The layout illustrates the changes done in a cutting tool within 1. 3 million years ago. We can see the front, back, and side views in the diagram of the cutting tool. Overall, In tools from 1. 4 million years ago, there was no sharp edge and, in tools from 800 thousand years ago, sharp edges observed
To begin with, a frontal view of the stone from 1. 4 million years ago looked more of an ordinary fatted stone without any proper edges. Looking at the side view of the stone, we can identify a few cracks, which indicate that it was not a planned tool. It shows the underdeveloped brain of the primitive era.
On the other hand, we had a cutting tool 800, 000 years ago. Comparing tools from 800, 000 years ago with the ones from 1. 4 million years ago, we could observe that tool has more sharp edges and looks more planned.
