ABSTRACT:
A method and apparatus for producing a non-linear, ornamental edge along a cement siding workpiece. In accordance with one embodiment of the invention, a first cutting blade is configured to have a non-linear shape corresponding to a shape of an ornamental feature that is to be cut in the cement siding workpiece. A second cutting blade is then configured to have the non-linear shape of the first cutting blade. The first and second cutting blades are aligned with one another to position a first cutting edge on the first cutting blade opposite to a second cutting edge on the second cutting blade. A cement siding workpiece is then positioned between the first and second cutting blades so that the first and second cutting blades are aligned with a location at which an ornamental feature is desirably formed on the workpiece. The first and second cutting edges are subsequently driven into the cement siding workpiece until the first and second cutting blades shear through the workpiece and form a non-linear, ornamental edge along the workpiece in the shape of the first and second cutting blades.
