Abstract
A screwdriver includes an elongated shaft including a first engagement surface, and a handle including a second engagement surface opposing the first surface. The handle receives the shaft and allows limited axial movement of the shaft relative to the handle in a direction parallel to the longitudinal axis of the shaft between a rotation transmitting position in which the first and second engagement surfaces are in contact with one another during rotation of the handle and a disengaged position in which the first and second engagement surfaces are out of contact with one another during rotation of the handle. The first and second engagement surfaces mate with one another to prevent relative sliding movement between the surfaces when they are in contact with one another so that the handle and shaft rotate together when the shaft is in the rotation transmitting position. The shaft rotates freely relative to the handle when the shaft is in the disengaged position, and is biased toward the disengaged position.
