The diagram below shows the development of cutting tools in the Stone Age.
The illustration depicts the evolution of stone cutting tools used by prehistoric men during the period from 1.4 million years ago to 0.8 years ago in the Stone Age.
Overall, it is noticeable that the key difference in the two versions of the cutting tool is the size, with the latter one becoming remarkably larger. Furthermore, tool B appears more refined than tool A according to shape and sharpness.
Tool A, which dated back 1.4 million years ago, was relatively small, primitive and resembled a natural stone, suggesting little craftwork involved. The tool measured approximately 7-8cm in height and 3-4cm in width. From the front and side view, it is clear that Tool A had an oval shape, rough surface and blunt edge.
However, 600,000 years later, the cutting tool used by men in the Stone Age had become more significantly advanced. First of all, they were much larger, nearly doubling the size of the previous version, and displayed a waterdrop shape: fat at the base and aggressively thinner towards a sharp point. Secondly, both front and back sides of the tool were ground more evenly and smoothly. Thus, these features rendered this version to be more superior in terms of cutting efficiency.
