Zusammenfassung:The invention relates to shears, in particular pruning shears or secateurs (1), comprising a first shear part (3) and a second shear part (3'). Each of the first and second shear parts (3, 3') have a cutting blade (11, 11') and a shaft or lever arm (5, 5') which are arranged at opposite sides of a pivot (7) which rotatably connects the first and second shear parts (3, 3') with each other. The shears further comprise a laminated or flat spring element (27) acting upon the first and second shear parts (3, 3') to move the shears on to an open position. The laminated or flat spring element (27) comprises a first portion (27') fixedly arranged at or allocated to the first shear part (3) and a flexibly arranged second portion (27") acting on the second shear part (3'). In order to firmly fix the laminated or flat spring element (27), first supporting means (37) are provided supporting the laminated or flat spring element (27) in axial direction to prevent a movement of the laminated or flat spring element (27) towards the pivot (7). Further, second supporting means are provided supporting the first portion (27') of the laminated or flat spring element (27) in radial direction to prevent twisting and/or bending and/or radial movement of the first portion (27').
