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.
