What is unique about an offset screwdriver?

An offset screwdriver is specifically designed to access screws in tight or confined spaces where a standard screwdriver may not fit. The handle of the offset screwdriver is angled, allowing for greater maneuverability and enabling the user to turn screws that are situated in hard-to-reach areas, such as between two closely positioned objects or in corners.

While other screwdrivers might have different characteristics, such as the type of blade, adjustability, or being powered by electricity, these features do not define the unique functionality of the offset screwdriver. Its primary advantage is the angled design, making it particularly useful for precise and awkward screw driving tasks.
