What is the classification of screw driver?

Screwdrivers are classified based on their blade types and the types of screws they are designed to drive. The most common classifications include flathead (or slotted), Phillips, Torx, and hex screwdrivers. Additionally, they can be categorized by size, handle type (e.g., electric or manual), and material. Each type is suited for specific applications, depending on the screw design and the torque required.
