A brake for bending sheet metal and including a bending leaf which is hinged to the workpiece clamping portions of the break by means of an integrally extruded, pin-less hinge. The bending leaf also is provided with an offset handle, so that the workpiece contacting portion of the bending leaf is of reduced size to fit within a previously formed portion of the workpiece. The hinge design includes interfitting protuberence and recess elements which are assembled by axial sliding movement, but which cannot radially disengage over the entire pivot range of the hinge, which range is sufficient to bend the workpiece over 90 DEG .
