Shapton Kuromaku – colour-coded Japanese stones for fast sharpening
Shapton Kuromaku, also known as Ha-No-Kuromaku, are high-quality Japanese synthetic sharpening stones designed for fast, precise and repeatable sharpening. Each grit has its own colour, so the stones are easy to identify when using several sharpening steps.
The Kuromaku range is popular thanks to high hardness, fast material removal and practical use. The stones wear less than softer water stones and usually do not require long soaking. Just moisten them with water and start sharpening. This makes them suitable for home cooks, professionals, sharpeners and craftsmen.
In this category you will find grits from very coarse #120 and #220 through repair grit #320, universal #1000, honing grits #1500 and #2000, finishing grits #5000 and #8000, up to very fine #12000. The range covers repairs, basic sharpening, honing and edge polishing.

Each grit has its own typical colour, so you can easily recognise coarse, basic, honing or finishing stones. |
Kuromaku stones come in a plastic case that makes storage easier and, depending on use, can also help as a simple sharpening base. |
|
Usually it is enough to moisten the stone with water. You do not need to wait long minutes as with softer soaking stones. |
Kuromaku stones are harder, hollow less and do not need flattening as often as softer water stones, although flatness should still be checked. |
How to choose Shapton Kuromaku grit?
The Kuromaku range covers the full sharpening process from repair to very fine polishing. For a common kitchen knife, #1000 is the most important grit. If the edge is very dull or damaged, start with a coarser grit. If you want a cleaner cut or a finish for Japanese knives, continue with finer stones.
| Grit / colour | Use | When to choose it |
|---|---|---|
| #120 white | Very coarse sharpening, major repairs, heavy material removal | Only for more experienced users, damaged edges or changing geometry. |
| #220 moss | Coarse restoration of very dull edges, faster removal and repairs | When the knife is neglected, has chips or needs bevel restoration. |
| #320 blue-black | Repairs, noticeably dull knives, preparation before #1000 | A practical coarse step before basic sharpening. |
| #1000 orange | Basic sharpening, working bevel restoration, regular maintenance | The most universal first stone for kitchen knives. |
| #1500 blue | Finer basic sharpening and smooth transition between #1000 and #2000 | When you want a slightly finer working edge than after #1000. |
| #2000 green | Honing, bevel smoothing, cleaner kitchen cut | After #1000 or as a finer working finish for kitchen use. |
| #5000 wine red | Fine finish and polishing after medium grits | For quality kitchen and Japanese knives when you want a smoother cut. |
| #8000 melon | Final honing, fine polishing, very clean cut | Only after previous sharpening, mainly for thinner and harder blades. |
| #12000 yellow | Very fine polishing and specialised finish | For experienced users, razors or maximum fine finishing after previous steps. |
|
Simple rule for Shapton Kuromaku As the first stone choose #1000 orange. For repairs add #320 blue-black. For a cleaner kitchen cut continue with #2000 green. For Japanese-knife finishing use #5000 or #8000. #12000 is specialised polishing. |

Who are Shapton Kuromaku stones suitable for?
Shapton Kuromaku is suitable for chefs, home enthusiasts, sharpeners and craftsmen. They work well on kitchen knives, Japanese blades, carbon and stainless steels, but also on tools such as chisels and planes. Their main value is fast and clean work without long stone soaking.
| Use type | Kuromaku recommendation |
|---|---|
| First quality stone for kitchen knives | #1000 orange as a universal base. |
| Damaged or very dull edge | #320 blue-black, or #220 / #120 for more experienced users. |
| Japanese kitchen knives | #1000 for the base, #2000 for honing, #5000 or #8000 for finer finish. |
| Tools, chisels and planes | Coarser stone according to edge condition and finer stone for finishing the working bevel. |
How to use Shapton Kuromaku correctly?
Use Kuromaku stones with water. Before sharpening, moisten the working surface and keep a water film on the stone. Do not use oil. For most European kitchen knives, hold an angle of approximately 15–20° per side. With Japanese knives, respect the original edge geometry.
Start with a grit according to knife condition. Coarse stones #120, #220 and #320 remove material quickly, so work with them in a controlled way. For a normally dull knife, #1000 is enough. After basic sharpening, continue with #1500, #2000, #5000 or #8000 depending on the desired edge refinement.
Kuromaku vs. GlassStone vs. RockStar

RockStar is a premium range with very fast sharpening and polishing effect. If you want the clearest and very practical SHAPTON range for common and advanced sharpening, Kuromaku is an excellent choice.
| SHAPTON range | When to choose it |
|---|---|
| Kuromaku | When you want colour-coded stones, a practical case and fast use without long soaking. |
| GlassStone | When you want a professional stone on a glass backing with low profile and precise performance. |
| RockStar | When you want a premium range with fast sharpening and polishing effect. |
Care for Shapton Kuromaku
After sharpening, rinse slurry and metal particles from the stone. Let it dry and store it in the case. Do not store the stones permanently in water. Although Kuromaku wears less thanks to its harder construction, check the working surface regularly and flatten it when needed.
When switching to a finer stone, rinse the blade and your hands so coarser abrasive does not transfer to the fine surface. With finishing stones such as #8000 or #12000, cleanliness is important for a smooth and precise result.
|
Warning Coarse stones #120, #220 and #320 remove material very quickly. Use them mainly for repairs and very dull edges. Fine stones #8000 and #12000 should be used only after previous sharpening, not as the first step for a dull knife. |
