A crowbar, also known as a LEVER or PRY bar, is a tool used to apply force in order to move or lift objects. It consists of a metal bar with a single curved end and flattened points, often with a small fissure on one or both ends for removing nails. The curved end is used to apply leverage and the flattened points are used to PRY objects apart. Crowbars are commonly used in construction, demolition, and other manual labor tasks.
