A tool is any physical item that can be used to achieve a goal , especially if the item is not consumed in the process. Tool use by humans dates back millions of years, and other animals are also known to employ simple tools.
Tools that are used in particular fields or activities may have different designations such as "instrument", "utensil", "implement", "machine", "device," or "apparatus". The set of tools needed to achieve a goal is "equipment". The knowledge of constructing, obtaining and using tools is technology .
Anthropologists believe that the use of tools was an important step in the evolution of mankind . Because tools are used extensively by both humans and wild chimpanzees , it is widely assumed that the first routine use of tools took place prior to the divergence between the two species. These early tools, however, were likely made of perishable materials such as sticks, or consisted of unmodified stones that cannot be distinguished from other stones as tools.
