Information about the grit sizes of DMT sharpening stones
The grit sizes of a diamond stone and a water stone can not easily be compared. This is because the construction and the used materials are significantly different. The sharpening grits of a water stone are incorporated in the stone. These grits will come loose from the stone during sharpening, creating some sort of sharpening paste. In a diamond stone, the diamonds are fixed in the surface of the stone.
Important to know
With DMT sharpening stones you can choose to sharpen either dry or wet. The advantage of wet sharpening is that the stone is lubricated and the sharpening remains are removed. You should always use water, not oil, for wet sharpening. Also, it is important to know that a diamond stone has to be made ready for sharpening. A new sharpening stone works just a little too coarsely. Only after 5 to 10 knives the stone works as intended.
