A tool is a device used to augment a species' natural abilities. The most basic tools are the simple machines.

Although tools were once thought to be used only by humans, it has been observed that chimpanzees and other animals, mostly primates, but also for instance ravens, are able to use them as well.

Knives are amongst the oldest tools and have been fabricated since the stone age.

Most tools can also be used as weapons, such as the hammer and knife. Similarly, weapons, such as explosives can be used as tools.

List of tools:

An instrument is a concrete or abstract tool, in particular a refined one.

Toy tools are popular. Some are essentially similar to the real thing, and just a cheap and/or small version, for example a shovel and bucket[?] to use on the beach and in the sandbox. Others are less functional, e.g. a dull plastic knife, or not functional at all.

In computing, software programs that assist people doing work on computers are also called tools, such as Computer Aided Software Engineering tool, Lint programming tool, software or web-based collaborative tools, software development tools.


Use of tools started at the beginning of the Stone age.

Tool can also refer to a person who is being manipulated by someone else, in a similar sense as puppet.

Tool is also a heavy metal band from Los Angeles; see Tool (band).
