Prior to sharpening, place the stone in water for 5 to 10 minutes to allow the whetstone to absorb sufficient moisture. Hold the knife so that the blade meets the coarse side of the whetstone at an angle of 10 to 15 degrees, then complete the process on the fine side. For best results, the front of the blade should be polished about 70% and the back of the blades about 30%. After sharpening, knives should be washed in hot water and then dried thoroughly.
