Product information
The Japanese water stone manufacturer Shapton, from Nabatame, Tochigi Province, probably fabricates the hardest stones. Compared to almost any other brand, Shapton stones tend to stay flat longer and need far less frequent dressing.
Shapton sharpening stones excel at rough-sharpening an edge and at quickly producing an effective edge. The sharpening experience will be quite different to that encountered on softer stones. You can feel the relative hardness of the Shapton stones, and you will find yourself checking all the time whether you’re actually removing material. But you are, and what’s more, surprisingly quickly!
The 120 grit stone cuts about as quickly as the 240 grit Sun Tiger from Matsunaga, and, as noted above, holds its flat surface much longer. You can make the rougher stones cut even more quickly if you apply a little more pressure than is usual with softer stones.
The 1000 grit Shapton stone cuts faster than traditional Japanese 1000 grit stones, but if you examine the edge under a microscope, you’ll finds that the edge appears somewhat rougher than would be the case with a traditional 800 grit stone.
In contrast to traditional and Cerax 8000 grit water stones, the Shapton 8000 hardly polishes the blade; instead it leaves a very fine matt surface. It is not certain whether this affects the final effective sharpness, but it is well known that some of the finest and most expensive Japanese natural stones also do not leave a mirror finish, and the final sharpness that can be achieved with those stones is justly famous.
Do not soak these Shapton stones in water before or between sharpening sessions.
