Kasumi Combination Water Stones keep the edges razor sharp on your knife blades. The #8000 grit has been specially developed for super finishing knives. The #8000 grit is almost the same grit and quality of a natural water stone used to sharpen Japanese Samurai swords. You will find that the combination #3000/#8000 whetstone will give your knives a beautiful mirrored edge just like the edge of a Samurai sword.

Simply place the water stone in water and wait until the bubbles disappear (10 to 15 minutes). With tip pointing away from you, a right-handed person should start to sharpen on the right side of blade. A left-handed person should start to sharpen on the left side of the blade. Hold the knife tightly and draw the edge backward and forward at an angle of 10-20°. It is best to sharpen starting with the tip of the edge first, followed by the middle, and finally the lower part of the edge. On each step when you feel the burr at the side opposite to the one you are sharpening, it is time to move to the next part to be sharpened. Repeat the same process for the other side of the blade. The opposite blade side needs less work and when the burrs are gone, you are finished. The powder that forms on the stone is essential to the sharpening process and should not be rinsed away. After sharpening, the knives should be washed in water and dried completely with a soft towel.

The included flattening stone makes the surface of the water stone flat again. After some use, the surface of the water stone will become uneven. When this happens, please grind the surface of the water stone with this stone to make it flat. A flat surface is best for sharpening your knives.
