Japanese water stones: Shapton Ha-no-kuromaku line

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.

NOTE: We offer the Shapton product line called Ha-no-kuromaku which means "edge behind the scenes".

Enlarged views and user information. Read these notes carefully. You will find out, among other things, why Shapton stones should not be left in water any longer than absolutely necessary. Apart from this important point, you will find the answers to many other pertinent questions about these stones. The manufacturer offers advice on the choice of grit grades for the different stages of sharpening various kinds of tools and common steels. The advice covers only general guidelines for using the stones. If you have different ideas, have had other experience with this type of stone, or know of different recommendations from other expert sources, you should take these into consideration when deciding on which stones to purchase.

Water stones become concave with use and require periodic reconditioning. Our flattening stones will do this job. A flat stone is indispensable for effective sharpening, especially of flat chisel and plane blades.

Note: All grit grade specifications refer to the Japanese JIS norm
