Overall, it was an extremely slow process which took thousands of years to improve the tool.

Moving to detailed description of the most primitive tool, it can be clearly seen that the first stone tool came into existence almost 1.4 million years ago which did not have a very precise shape and sharp edge. It was almost 5cm in size from side to side and from its side view it can be understood that it was not very sharp. The assumption is that such stone tool might have been used for smashing insect shells or fruits in order to access food especially extracting nuts.

However, as human became more intelligent and the stone carving skills improved a better stone tool was designed which seems to be more effective for purpose.
