Brief History
Hand tools have been used by humans since the
stone age when stones were used for hammering
and cutting. During the bronze age tools were
made by casting the copper and tin. Bronze tools
were sharper and harder than those made of
stone.

Brief History
During the iron age, iron replaced bronze,
and tools became even stronger and more
durable. The Romans developed tools
during this period which are similar to those
being produced today. In the period since
the industrial revolution, the manufacture of
tools has transitioned from being craftsman
made to being factory produced.
