This dual grit sharpening stone is great value for money. The coarse which is 160 grit, brings the edge of the knife back into shape in no time with little effort needed. The fine side is 800 grit and will put a nice sharp finish to the edge. The stone is made of ceramic bonded aluminum oxide, which makes the grains cut deep into the steel and give you a sharp result quickly.
Soak the sharpening stone in water for a few minutes. This creates a layer of water on the stone that helps remove the residue. It ensures you can sharpen quickly and it also increases the lifespan of the stone. Don’t put pressure on the knife and let the stone do the heavy work!
