The Shun 300 & 1000 Grit Combination Water Stone is double sided and comes with a rubber base to secure the stone while sharpening. Grit #300 is used to repair nicks, damaged edge blades or dull knives. Grit #1000 is used for basic sharpening. Before sharpening, pre-soak the whetstone for 10-20 minutes and keep the stone slightly wet during the sharpening process. Next to taking your knives to a professional sharpener, this is the choice sharpening method of many chefs.

Prior to using the whetstone, it should be completely soaked in water for about 10 to 20 minutes. Please make sure that the stone is always slightly wet during the sharpening process. When sharpening single-edged knives the ground side should be treated first. Make sure that you maintain the angle given by the manufacturer. If at all possible apply an angle of 45° (to achieve the best possible surface). Grind towards the edge using pressure; release the pressure on the way back. Apply as often as necessary to achieve the desired degree of sharpness. Once finished on this side, turn the blade over and start on the other side but only approx. 1/10th as often as before. Double-edged knives need the same treatment but with an angle of 15°. Both sides need to be ground evenly to restore the symmetrically ground edge.
