A Robertson screwdriver is a type of screwdriver with a square-shaped tip, designed to fit into screws with a matching square-shaped socket in the head. This design allows for a secure grip, reducing the chance of the screwdriver slipping out of the screw. Robertson screwdrivers are popular in woodworking and construction, as they provide a strong connection and can handle force without damaging the screw. The square shape helps prevent the screwdriver from falling out, making it easier to use in tight spaces or when driving screws quickly.
