The first people made tools from stone. What is the advantage of metal tools?

Primitive people were mainly engaged in appropriating activities. Initially, they made tools from stone. This process was lengthy and ineffective. With the advent of metal, people were able to make new tools. Metal tools had an advantage over stone ones, as they were much sharper and stronger. After mastering the metal, people received objects of various shapes and densities, which were used for hunting, arable farming and agriculture.
