The correct term for the fast cutting Norton silicon carbide stone I use is, "Norton Crystolon, medium".

In 1893 a man named Edward Goodrich Acheson invented and recieved the United States patent for the process by which silicon carbide is made, he then went on to invent and patent the oven that did this.
His patents are recognized as some of the most important patents resposible for the modern industrial age because these abrasives could cut hard steel to high accuracy in machine processes. The name of Mr. Achesons silicon carbide was "Carborundum".

Sometimes I get confused.
