Cobalt Steel and the Grinding Wheel. Before I mess up my stone, I thought a quick post here may be extremely prudent. I have an older SuperGrind 2000 (Square cabinet, no serial number). The stone is not marked with a part number. The label says "SuperGrind" and it is the light grey stone. I would believe it is the original stone to the tool.
