Terms of the Trade: What Is a Slotted Screwdriver?
The distinguishing characteristic of a slotted screwdriver is its flat, blade-like tip. Designed to fit into screws with a slot or flat impression, slotted screwdrivers do not have a pointed tip with ridges on the side as do Phillips-head screwdrivers. The slotted, or slot head screwdriver, is the oldest and most commonly found screwdriver. It also goes by the names flat-head, flat-tip, straight, and common blade.
