Crowbλr Enthusiasts

that's a good question

what do crows have to do with bars?

The least expensive, most common crowbars are forged from hexagonal or sometimes cylindrical stock. More expensive designs may be forged with an I-shaped cross-section shaft.

Normally made of medium-carbon steel, they can alternatively be made from titanium, which has the advantages of being lighter and nonmagnetic.

It is used as a lever either to force apart two objects or to remove nails. Crowbars are commonly used to open nailed wooden crates, remove nails, or pry apart boards. Crowbars can be used as any of the three lever classes but the curved end is usually used as a first-class lever, and the flat end as a second class lever. In mining, crowbars are used to break and remove rock, but not as much in modern mining.

A crowbar, also called a wrecking bar, pry bar or prybar, pinch-bar, or occasionally a prise bar or prisebar, and more informally or known to non-American nations such as Britain and Australia as a jimmy (also called jimmy bar or jemmy), gooseneck, or pig foot, is a tool consisting 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. In Britain, Ireland, New Zealand, and Australia, due to the influence of American media "crowbar" may occasionally be used loosely for this tool, but it is still mainly used to mean a larger straighter tool, its original English meaning (see digging bar). The term jemmy or jimmy most often refers to the tool when used for burglary.
