Abstract: A forming tool comprising a relatively rigid shank portion or holder mounting in bearing relation thereto and for limited rotation thereon an operating head. In the preferred embodiment illustrated the operating head is in the nature of a generally cylindrical body having a V-shaped notch. The formation of the notch in the cylindrical body produces thereon a pair of laterally spaced bearing surfaces for application to material to be worked, one of which functions as a fixing means and the other of which functions as a bending means.
