A hand tool is a device for performing work on a material or a physical system using only hands. The hand tools can be manually used employing mechanical force, or electrically powered, using electrical current.
Examples are almost endless, from general tools like the hammer to specific tools like callipers. Some hand tools are mounted to walls, such as pencil sharpeners.
Virtually every type of tool can be a hand tool, and many have also been adapted as power tools, which get their motive power from motors or engines rather than from human mechanical action. Some hand tools cannot be easily or safely converted to power tools, for example chisels. Other examples are used by laborers such as hammer and saw.
