A tool or device is a piece of equipment which typically provides a mechanical       
advantage in accomplishing a physical task, or provides an ability that is not       
naturally available to the user of a tool. The most basic tools are simple           
machines. For example, a crowbar simply functions as a lever. The further out       
from the pivot point, the more force is transmitted along the lever. When           
particularly intended for domestic use, a tool is often called a utensil.           
Observation has confirmed that multiple species can use tools, including monkeys,   
apes, several birds, sea otters, and others. Philosophers originally thought

Some tools can also serve as weapons, such as a hammer or a knife. Similarly,       
people can use weapons, such as explosives, as tools.
