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.
