Never use diamond stones dry. This is bad for the surface of the diamond stone, and will not sharpen well, either. Wet the sharpening surface before every use! You should also be careful not to put too much pressure on the surface when sharpening, and absolutely not near the edges of the plate, as this can deform the plate and scrape off the diamond coating.
