ABSTRACT:
In one embodiment, a screwdriver having interchangeable bit bodies with permanently affixed bit heads is provided. In another embodiment, at least one transparent end cap is provided to display a bit head in an engaged position ready for use. In another alternative embodiment, transparent end caps are provided at two ends of the screwdriver. In still another embodiment, two end caps are provided that may nest with each other. In yet another embodiment a rotatable end cap is provided. The various embodiments of the precision screwdriver may be utilized independently or in combination. One combination provides a screwdriver comprising two transparent, nesting, and rotating caps. A user can apply pressure to an end cap top (whether nested or not) to stabilize the screwdriver for a particular job while rotating the screwdriver independent of the nesting cap top.
