Crowbar (tool)

From Wikipedia, the free encyclopedia

Jump to: navigation, search

A crowbar, also called a pry bar or prybar, or more informally known as a jimmy, jimmy bar[citation needed] or jemmy (British Isles), is a tool consisting of a metal bar with a single curved end and flattened points, often with a small fissure on the curved end for removing nails. In the British Isles "crowbar" may be used loosely for this tool, but is more commonly used to mean a larger straight tool (see spud bar); the term "jemmy" most often refers to the tool when used for burglary.

It is used as a lever to either force apart two objects or to remove nails. Crowbars are commonly used to open nailed wooden boxes. Another common use for larger crowbars is general demolition: for removing nails, prying apart boards, and generally smashing things. It has also been used as a weapon in hold-ups.

Crowbars can be used as any of the three lever classes but are generally used as a 1st or 2nd class lever.

[edit] Materials and construction

Normally made of medium carbon steel, they can be made from titanium also, which has the advantage of being lighter, nonmagnetic, and spark-resistant.

The least expensive, most common crowbars are forged from hexagonal or sometimes cylindrical stock. More advanced, expensive designs often are forged with an I shaped cross sectional shaft similar to an I-beam. This shape makes them more resistant to bending.

[edit] Etymology

  • There is a popular story that the term crowbar derives from Jim Crow and they were used by blacks to perform menial tasks, and the word thus has racist origins. This is a false etymology; the term crowbar traces to at least 1400; and is not in any sense racist. As they resembled the feet or beaks of a crow, they were first called crow bars; later the two joined into one word.[1] They also were called crows; William Shakespeare used the term crow in many places[2], including his written-in-the-1590s play Romeo and Juliet, Act 5, scene ii:
Get me an iron crow and bring it straight.
Unto my cell. ... [clarify]

[edit] Popular culture

In some computer games a crowbar is the basic mêlée weapon wielded by the player character; this practice appears to have been started in 1998's Half-Life.

Examples include:

Many pieces of zombie-related fiction, such as Max Brooks' The Zombie Survival Guide, make special note of the crowbar as perhaps the best all-around mêlée weapon—not only does it make a useful tool, but it is light enough to be carried and wielded quickly and is also heavy and durable enough to deal an effective blow, with a pointed end capable of penetrating a skull. As zombies traditionally cease function when the brain is destroyed, this is extremely important in combat with them.

In the videogames:

The crowbar is used to break padlocks
