Abstract: A device for cutting sheet metal is disclosed. The device comprises of a cutting blade (13) which passes between two curved sharpened support blades (12 & 14) (“curved support blades”), the latter which curves away from the cutting blade (13). The cutting blade (13) and the curved support blades (12 & 14) each have two holes in them (henceforth referred to as upper and lower holes) which enable them to be connected together and to the handles (4 & 5). The handles (4 & 5) are long and similar to those commonly used in long handle pruning secateurs. Items (3 & 6) each have two holes in them (henceforth referred to as upper and lower holes) which enable them to be connected together and to the cutting blade (13) and the curved support blades (12 & 14). Items (3 & 6) are bolted together at their upper holes, and at the other ends they slot into the handles (4 & 5).
