A crowbar is a metal tool designed to be used as a lever. It is very basic in design and it is likely that humans have been using versions of this tool for centuries. It has a wide range of uses and is commonly used in demolition work as it can be used to separate things and also to open things like boxes that have been nailed shut. Levers are stocked by many hardware stores and can also be ordered directly from their manufacturers.
A basic lever is simply a straight metal bar with a curved end. The curved end has a forked piece of metal that can be used as a clasp to pull out nails and similar obstacles. The other end is usually chisel-shaped; It is also possible to find levers with handles in easy-to-grip materials, making them more comfortable to use. Those with a chisel point can be used as a very effective wedge, driving the chisel into a small space and then twisting the shank of the tool.
The term “crowbar” has been around since the 15th century and is thought to be a reference to the crow’s foot, which the curved end of the tool closely resembles. Originally, this tool was called a “crowbar”; at some point the word became compounded, though exactly when this occurred is unclear. It is also possible that the term is derived from Old French crocodile, meaning “hook”. Levers are also known as levers or levers, and in some communities they are called Jimmy or Jimmy Bars.
The most common material choice for these tools is steel or iron because both materials are strong and very durable. It is also possible to find levers made of titanium and other special materials. Some companies make versions that don’t conduct electricity, which can be a distinct advantage; they are usually more expensive because the materials used to make them are more expensive. For people who struggle with tool theft, levers in bright colors or with bold floral patterns are also available, although the paint tends to wear off with use.
When selecting a lever, it pays to look for one that is heavy and very sturdy. A solid one will give years of productive use, while cheaper versions can break at inconvenient times. It can also be helpful to get various sizes of levers to ensure shorter or longer levers are available as needed.
