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.
A common hand tool, the crow bar is typically made of medium-carbon steel, possibly hardened on its ends.[citation needed]
Commonly crowbars are forged from long steel stock, either hexagonal or sometimes cylindrical. Alternative designs may be forged with a rounded I-shaped cross-section shaft. Versions using relatively wide flat steel bar are often referred to as "utility" or "flat bars".[citation needed]
The accepted etymology[2][3] identifies the first component of the word crowbar with the bird-name "crow", perhaps due to the crowbar's resemblance to the feet or beak of a crow. The first use of the term is dated back to c. 1400.[4] It was also called simply a crow, or iron crow; William Shakespeare used the latter,[5] as in Romeo and Juliet, Act 5, Scene 2: "Get me an iron crow and bring it straight unto my cell."
In Daniel Defoe's 1719 novel Robinson Crusoe, the protagonist lacks a pickaxe so uses a crowbar instead: "As for the pickaxe, I made use of the iron crows, which were proper enough, though heavy."[citation needed]
