A hand tool is an implement for working on a material or physical system with the use of one’s hands. Hand tools may be manually used, with mechanical force. Some hand tools are driven by current from mains supplies or batteries.
There is a large spectrum of hand tools catering to distinct uses. Some tools, such as the hammer, have many applications. Other tools, such as the calipers, are used only for specific purposes. There are portable hand tools, while some, like pencil sharpeners, can be mounted or fixed.
