What tool is characterized by a strong steel bar commonly used for prying?

The tool characterized by a strong steel bar commonly used for prying is known as a prybar. This tool is designed specifically for leveraging and removing objects, often utilized in automotive repair and general construction tasks. Its rigid structure and straight design enable users to exert significant force when prying, making it ideal for tasks such as pulling apart materials, removing nails, or dislodging stuck components.

A prybar typically features a flat end that can be wedged into tight spaces, allowing for effective leverage. Its strength ensures that it retains its shape and functionality even under considerable stress. This makes it an essential tool in any automotive technician's toolkit, especially when dealing with components that require careful manipulation without causing damage.

Other choices like an abrasive pad, ball peen hammer, and scratch awl serve entirely different purposes. An abrasive pad is used for smoothing surfaces, a ball peen hammer is primarily for shaping metal, and a scratch awl is designed for marking or making small holes in materials. These tools do not possess the specific characteristics or functions that define a prybar.
