A screwdriver includes a shank, a ratchet assembly, and a handle. The shank includes a shank extender that in an extended position lengthens the shank and in a retracted position is stored within the handle of the screwdriver. The ratchet assembly includes a knob and is configured to drive in the same direction the knob is turned. The screwdriver includes a locking mechanism to prevent unwanted movement of the shank between the extended and retracted positions. The handle of the screwdriver includes a storage space to hold alternative screwdriver bits and a stabilizing component to decrease movement of the handle when the storage portion is in an extended or open position. In a closed position the handle surrounds the alternate bits and in an open position the alternate bits are exposed.

A ratchet screwdriver includes a direction-switching apparatus. The direction-switching apparatus includes a cylinder, a toothed wheel, two pawls, two springs and a connector. The cylinder includes a wheel-containing chamber in communication with two pawl-containing chambers. The toothed wheel is inserted in the wheel-containing chamber. The pawls are respectively inserted in the pawl-containing chambers. Each of the springs is connected to one of the pawls in one of the pawl-containing chambers. The connector interconnects the springs so that at least one of the springs keeps at least one of the pawls engaged with the toothed wheel to allow the cylinder to rotate the toothed wheel in at least one of two directions.
