Microplane is shipped free across Canada on orders over $99. Most graters on the market use a stamped metal process, resulting in teeth that are the same thickness as the rest of the blade. As a result, stamped blades are dull. Microplane however utilizes a chemical process called photo-etching that defines and sharpens the edge of each tooth on the grater. The result is a much sharper tooth, giving the user a more precise result with far less effort.
