What are the three basic parts of a screwdriver?

The three basic parts of a screwdriver are indeed correctly identified as the blade, handle, and shank.

The blade is the flat or Phillips end that engages with the screw head. The handle provides the user with a grip and allows for the application of torque, making it easier to turn screws. The shank, which connects the blade to the handle, generally refers to the long, narrow part of the screwdriver that includes the blade and extends from the handle.

These components work together to perform the screwdriver's function of screwing and unscrewing fasteners effectively. Understanding these parts is crucial for selecting the correct screwdriver for the task at hand, as different types of screws require specific blade shapes and sizes to fit properly.
