The metal panel shear cutter of the instant invention is designed for metal panels which include support ribs. The panel cutter utilizes an anvil type cutting blade positioned at each side of the cutting base. Each cutting blade is pivotally connected to a cutting base in the vertical plane. The cutting base also includes recesses in the top surface of the base for receiving the ribs of the panels when the panels are placed on the shear cutter with the ribs face down, to allow for a smooth and clean cut of the panel. The cutting blades and a small portion of the base are also pivotally connected to the cutting base in the horizontal plane so they may be pivoted to the desired cutting angle while the metal panel remains fixed with respect to the base. This pivotal portion of the base includes additional recesses in the top surface thereof for supporting the ribs of the panel. These recesses in the pivotal portion of the base are substantially the same size as the ribs of the panel to permit a clean cut. The recesses in the cutting base are larger than the ribs to permit the panels to be set and cut at various angles on the cutting device.
