The diagram below shows the cutting tools used by man 1.4 million years ago and 80000 years ago.
The illustration compares the cutting tools utilized by the early human in two separate times in terms of their figure and sharpness.
Overall, it is crystal clear that cutting tools had encountered significant changes since 1.4 million years ago until 80000 years ago regarding their form.
By 80000 years ago the rocks had become sharper at the edge and a bit rounder at the base which could make them easier to handle and more effective. In addition to this, in 1.4 million years ago the cutting tools seem to have a different bump and dump in various parts but these irregularities have disappeared in the time span. In such a context, the cutting tools appear to become oval which is thicker at the bottom and thinner at the top. Also, another variation is in their top which is more straight at the edge in 80000 years ago. In other words, the fluctuations at both edges had been omitted until 80000 years ago.
