A bending tool ( 12 ) for bending workpieces, especially plate and sheet metal blanks includes at least one bending element ( 23 ) positioned on one side of a workpiece as well as a retainer device with clamping elements ( 14, 42 ) on opposite sides of the workpiece. For bending the workpiece, the retainer is moved, together with the workpiece clamped on it, relative to a bending element ( 23 ). In the process, the retainer device with the workpiece and the bending element ( 23 ) move relative to each other in a bending stroke which contains a component in the bending-stroke direction as well as a component in the transverse direction of the bending stroke. The direction of the bending stroke is controlled by at least one control element associated with the bending element ( 23 ) as well as at least one guide element associated with the equal-sided clamping element ( 42 ). The last-mentioned guide element or elements can move in the bending-stroke direction ( 8 ) relative to the first-mentioned control element or elements ( 46 ).
