Seven Basic Tools of Quality

"A hand tool is any tool that is not a power tool – that is, one powered by hand (manual labour) rather than by an engine. Some examples of hand tools are hammers, spanners, pliers, screwdrivers and chisels. Hand tools are generally less dangerous than power tools." [Hand tool. Wikipedia]
"A power tool is a tool that is actuated by an additional power source and mechanism other than the solely manual labour used with hand tools. The most common types of power tools use electric motors. ...
Power tools are used in industry, in construction, in the garden, for housework tasks such as cooking, cleaning, and around the house for purposes of driving (fasteners), drilling, cutting, shaping, sanding, grinding, routing, polishing, painting, heating and more.
Power tools are classified as either stationary or portable, where portable means hand-held. Portable power tools have obvious advantages in mobility." [Power tool. Wikipedia]
