Abstract
A tool for bending sheet metal and in particular for making bends along the edges and a bend known as a cross break for duct work. A pair of longitudinal right angle members are spaced apart at each end and welded together forming a gap through which a piece of sheet metal is inserted. A pair of parallel rods are welded one to each one of the coplanar webs and perpendicular to the two right angle members at a selected position. The parallel rods provide a handle which may be squeezed to urge the gap closed and thus clamp and hold the sheet metal tightly between the two right angle members whereby the metal can be gripped and bent at the desired angle forming a crease therein.
