Crowbar

A crowbar, also called a wrecking bar, pry bar or prybar, pinch-bar, or occasionally a prise bar or prisebar, colloquially gooseneck, or pig foot, or in Britain and Australia a jemmy or jimmy (also called jemmy bar), is a lever consisting of a metal bar with a single curved end and flattened points, used to force two objects apart or gain mechanical advantage in lifting; often the curved end has a notch for removing nails. The design can be used as any of the three lever classes. The curved end is usually used as a first-class lever, and the flat end as a second-class lever. Designs made from thick flat steel bar are often referred to as utility bars. more »
