Whetstones, also known as water stones or sharpening stones, are used to grind and hone the knife edges. Using a holder, the sharpening task will be easier. Even the best kitchen knife will lose its initial sharpness over time. The sharpening devices and the right technique will make the sharpening task easy. Whetstones have different degrees, depending on the grain of the stone. A fine-grained whetstone is dense, sharpens less, but allows adjustments in the edge. In contrast, a coarse grain edge removes more material from the cutting edge. The higher the grain reference number, the smaller the grain size.
