Screwdiver

Screwdrivers come in all different sizes and types for all different types of jobs. There are several different style of heads like Phillips, PoziDriv and Slotted to mention but a few. You can also get screwdrivers that have spiral ratchet mechanisms, that rotate on the head when pressure is applied to the handle. I would avoid using screwdrivers for anything other than using it as a screwdriver, not recommended as a chisel or being hit with a hammer.
