I'm pleased to announced that I have expanded my offering of sharpening stones to include the 8" Dia-Sharp line from DMT, including the popular D8EE - Extra Extra Fine - 8000 Grit. So with the Norton Waterstones, my 6"x2" & 8"x3" Belgians, and now the 8" DMT diamond stones, I think I am going to have to reinforce the beams supporting the floor of my storeroom. My F-150 is parked in the garage right underneath.
