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.
