ABSTRACT:
A tool includes a handle having a shank extended from one end for engaging with and for driving fasteners. A driving stem has an extension for engaging into the orifice of the shank and has an engaging hole for receiving and driving the fasteners. The shank and the driving stem are extended from one end of the handle such that the handle may apply a greater torque against the driving stem. A cover is pivotally coupled to the handle and has one or more wheel members for forming a roller skate shape. The shank has a clamping device for clamping the driving stem in place.
