Title: Louver cutter

Abstract: A louver cutter comprising a body having a pair of spaced arms, the lower arm defining a base and the upper arm overlying the base. A lower die pad is rotatably mounted on the base for rotation about a vertical axis and is lockable in any adjusted position. A lower die block is fastened to the lower die pad such that the lower die pad has a portion projecting upwardly and spaced from the lower die block. A piston is slidable for vertical movement in said upper arm and means are provided for moving the piston toward and away from the lower die block. An upper die block is mounted on the piston and has an opening into which the piston extends. A fastener holds the upper die block on the piston. The upper die block has a vertical surface and a horizontal surface engaging the vertical and horizontal surfaces of a cutter blade. A resilient pad on the underside of said upper die block is adapted to engage the upwardly extending portion of said lower die pad during the final movement of the blade downwardly adjacent in cooperative relation with the lower die block.
