Knives were some of the first tools developed by humans. The image at the top shows a dagger dated to about 2900 BC. The one at the bottom shows a modern (20th century) one.

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 computer. Very basic things like knives and pens and pencils are also tools. The bludgeon (a stick or rock used to smash things) was one of the very first tools made by humans. The knife is also one of the first tools humans ever made.
