Question

Why do we say that the tools made during the Chalcolithic age were better than the tools of the Stone Age?

Answer 1

Answer:

Humans had previously worked with gold and, in a few isolated areas, some copper, the Chalcolithic Age saw the first large-scale production of copper tools. ... The metal was far more durable than the stone tools they had previously used, which could shatter if hit too hard. Metal tools could also hold a sharper edge.
