Abstract: A multi-function tool includes an extendible and retractable portion that becomes offset from a centerline position of the handle when in the offset position. A locking mechanism allows the workman to offset the shaft from a centerline position of the handle, or retract the shaft back into the handle into a centerline position. While the shaft is in the extended and offset position, the shaft rotates freely in either a clockwise or counterclockwise direction. When the shaft is retracted in the straight centerline position, a ratchet mechanism or gear box restricts shaft rotation in either a clockwise or counterclockwise direction, or allows rotation in either direction. The shaft can be extended and offset by means of a spring or other device that allows the locking mechanism to offset automatically or semi-automatically when the locking mechanism is activated. The shaft allows the workman to interchange bits or sockets for multiple applications.
