摘要： A device for cutting sheet material, especially sheet metal having a contoured structure such as ridges or corrugations, the device including (a) a support (21) adapted to attach the device to a power source (11) (manual, electric or hydraulic); (b) a first blade portion (15) with a first blade (19); (c) a second blade portion (16) with a second blade (20); (d) a first coupling portion (17, 13) which operatively couples the first blade portion (15) to the power source (11) and adapted to allow pivoting of the first blade portion (15) when the power source (11) is activated; and (e) a second coupling portion (18, 14) which either (i) operatively couples the second blade portion (16) to the power source (11 ) and is adapted to allow pivoting of the second blade portion (16) when the power source (11) is activated or (ii) is adapted to prevent the second blade portion (16) from pivoting when the power source (11) is activated, as required; wherein the pivoting of the first blade portion (15) and/or the second blade portion (16) provides a cutting action by the first blade (19) and the second blade (20). When only a single blade is to pivot, it is the lower blade which pivots upwards to meet the fixed second blade. The coupling portions (15, 16) can be adapted to enable a required grade of cut to be pre-determined from the cutting action of the device.
