About Miyabi Toishi Pro sharpening stones
The Miyabi Toishi Pro sharpening stones are based on the well-known Naniwa Chosera sharpening stones. These sharpening stones are extremely popular and renowned worldwide for their sharpening properties. Just like the Choseras, these Toishi Pro sharpening stones have excellent sharpening power and remove material quickly. In principle, they have been made for the maintenance of hard, durable Honbazuke-sharpened Miyabi kitchen knives, but they can certainly also be used for other knives (except ceramic kitchen knives).
Using the Miyabi Toishi Pro sharpening stones
Miyabi itself specifies that you need to immerse the stone in water for about five minutes before use. But we prefer to "splash & go": just sprinkle water on the surface or briefly wet it and you can get started right away. It is best to put the stone on a sharpening stone holder, such as the Miyabi Toishi Pro Base Kit, so you can be sure that the stone won't move while you're sharpening. For the best results, keep the stone good and wet during sharpening. While sharpening, a "slurry" is formed. This helps with the sharpening, so don't remove it. Have you finished sharpening? Then quickly rinse the sharpening stone, remove the slurry and allow the stone to dry completely. Store the stone in a cool, dry place, away from sunlight. Definitely do not keep the stones in water for a long period of time.
Because the stone gradually wears down with use, it remains sharp and clean for a long time. However, over time, the stone's effect may diminish somewhat. This is why we recommend using a dressing stone to keep the sharpening stone clean and sharp. By doing so, you can keep the stone in optimum condition. The dressing stone is also included in the aforementioned Miyabi Toishi Pro base kit.
