Tool

Tools are things used to make tasks easier. Tools have changed over time. The first tools were made in the Stone Age and Bronze Age. Throughout history, people have made many new and more complicated tools. Some examples of tools that are often used today are the hammer, the wrench also called a spanner, saws, shovel, telephone, and the computer. Very basic things like knives, pens, and pencils are also tools. The bludgeon a stick or rock used as a weapon to smash things was one of the first tools made by humans.

They were the first known tools used by mankind, and were used by all human species, such as Homo habilis and Homo erectus. Recently it was learned that stone tools were used before the genus Homo evolved. These oldest tools come from the shores of Lake Turkana in Kenya, and date to 3.3 million years ago. They are 700.000 years older than any tools found before. Volcanic ash and minerals around the tools allow them to be dated. The tools look like those described as Oldowan. They might have been made ...
