A sheet material cutter for shearing various widths of sheet material such as aluminum or plastic siding, soffit, facia board and flashing is provided which is readily transportable and useful in cutting a variety of widths of such sheeting. The cutter has a base, a shearing blade of a length greater than the maximum width of sheet to be cut, spaced apart shearing dies mounted on the base and defining a shearing slot through which the blade travels when shearing a width of material, and a post on the base to which the shearing blade is pivotally mounted. The shearing blade includes a pointed section which pierces the sheet material, first the remaining shearing edges of the blade shearing the material to each side of the pierced area to complete cutting of the sheet material. The shearing dies are mounted on plate members of the base such that when the plate members are secured in abutting relationship, a predetermined distance is defined between the shearing die edges to ensure a precision fit of the shearing blade as it passes through the shearing slot adjacent the edges of the shearing dies. In this manner minimum pressure is required in shearing various widths of aluminum and plastic materials without requiring anything other than manual power to operate the cutter.
