A crowbar with a curved chisel end to provide a fulcrum for leverage and a goose neck to pull nails

A crowbar, also called a wrecking bar, pry bar or prybar, pinch-bar, or occasionally a prise bar or prisebar, colloquially gooseneck, or pig bar, or in Australia a jemmy,[1] 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.
