A hand operated device and method for assisting a user in driving the device's shaft to impart driving force to a fastener more than conventionally accomplished in a fixed period of time. The device has a first member and a second member gripped with the user's first hand, while a handle of the shaft is held with the user's second hand. The user then turns the second member in a first direction, while still gripping the first member, so as to rotate the shaft. Next, the user releases grip on the second member while rotating the first member in a second direction, freely, without the first member ever rotationally engaging the shaft. Simultaneously, the user grips and rotates the handle in the first direction so as to continue to rotate the shaft. The user then repeats the aforementioned steps to drive the shaft as desired so that the first member never rotationally engages the shaft.
