Phillips Screwdrivers
Phillips screwdrivers have a cross on their tip that are designed to fit Phillips screws, which have a cross on their head and are the most widely used screws in the world.
They are so popular because unlike flat-head screwdrivers, Phillips head screwdrivers have a self-centering tip in the middle of the cross, meaning the screwdriver is less likely to slip when turning screws.
