Some examples are: hammer, wrench (also called a spanner), hoe, saw, and shovel. Even very basic things like forks and spoons, and pens and pencils are tools. The bludgeon (a stick or rock used to smash things) was the very first tool made by humans. The knife is also one of the first tools humans ever made.
A "tool" is also slang for the penis, or for a person that is easily fooled.
