A tool includes a handle device having a shank for driving tool members, and having a primary hand grip. An auxiliary hand grip is selectively attached to the primary hand grip, to increase a length of the tool by combining both the auxiliary hand grip and the primary hand grip together, and the auxiliary hand grip may be selectively detached from the barrel of the handle device, to decrease the length of the tool to only the primary hand grip. A tool device may further be received in the auxiliary hand grip, and removable from the auxiliary hand grip, for driving tool elements having a dimension smaller than that of the tool members. A casing may be secured to the auxiliary hand grip, to receive a tape measuring device.
