The diagram illustrates the progress of the different cutting gears belonging to the Stone Age Era. Overall, it is clearly seen that the measures of the cutting tools are preserved in terms of their lengths which were 5 cm for each different time line.

To begin with, the front and back view tool A which was used 1,4 million years ago had  similar apperiances and their width and length measures almost remained without any change. As for the side view of this tool, it quite obviously looks sharper than the other views. Also, in this age, people used less sharpened tools when compared with the Tool B in 0.8 million years ago.

Tool B had a similar apperiance with Tool A in 0.8 million year ago. However, the side view of the tool B was too thin. Also, it is seen that the front and side aspects of tool B were wider than those of tool A. The front view of the tool B had a circler shape and the back view had a flatten surface at the center of the this view.
