220 sharpening stone, Kuromaku SHAPTON K0706 moss green
Code: SHA-K0706Product detailed description
Coarse sharpening and edge repairs
Japanese SHAPTON Kuromaku JIS #220 sharpening stone
A coarse Japanese water stone for restoring very dull and damaged edges, removing minor chips and adjusting blade geometry. The JIS #220 grit removes material quickly while allowing more controlled work than the extremely coarse #120 stone.
SHAPTON Kuromaku #220 is intended for situations where a standard #1000 sharpening stone is no longer sufficient. It helps create a new bevel, restore a neglected edge or remove minor damage from the cutting edge. After coarse sharpening, we recommend continuing with the SHAPTON Kuromaku #1000 stone, which refines the newly formed edge and prepares it for everyday use.
The stone is made in Japan from a silicon carbide-based abrasive. It offers rapid material removal, high hardness and slow wear. The package includes a practical plastic case that can also be used as a basic holder during sharpening.

When should you choose #220 grit?
The JIS #220 stone is suitable as the first step when repairing a knife whose edge is too dull or damaged for normal sharpening.
- restoring a very dull edge,
- removing minor chips and small edge damage,
- creating a new sharpening bevel,
- adjusting the angle or edge geometry,
- preparing the blade before continuing on a #1000 stone.
Important notice
The #220 grit removes material considerably faster than a standard sharpening stone. Use only light pressure and regularly check the shape of the edge while working. For regular maintenance of an undamaged knife, a #1000 stone is generally sufficient.
Main benefits
- rapid material removal during edge repairs,
- suitable for very dull and slightly damaged knives,
- also usable on hard knife steels,
- hard bonding material and slow stone wear,
- low water absorption and quick preparation for use,
- plastic case usable as a basic holder,
- Japanese SHAPTON manufacture.

What is the difference between #120, #220 and #1000 grit?
JIS #120 – very coarse repairs
Extremely rapid material removal for heavily damaged blades, larger chips and substantial geometry changes. It is unnecessarily aggressive for routine maintenance. View SHAPTON Kuromaku #120.
JIS #220 – controlled coarse sharpening
A practical choice for very dull knives, minor damage and creating a new bevel. It provides rapid material removal with better control than #120 grit.
JIS #1000 – basic sharpening
A universal grit for restoring a normally dull edge and an essential follow-up step after using the #220 stone. View SHAPTON Kuromaku #1000.
Recommended sharpening procedure
- Wet the stone. Thoroughly splash the surface with water. If it dries quickly, you may soak the stone briefly.
- Ensure a stable position. The case can be used as a basic holder, but always make sure it does not slip on the work surface.
- Choose the correct angle. Guide the knife smoothly across the stone along the full length of the edge.
- Do not use excessive force. The coarse stone removes material quickly even with controlled pressure.
- Keep adding water. The surface must remain wet during sharpening.
- Check for burr formation. Then work on the other side of the edge.
- Continue on #1000 grit. This removes the deeper marks left by the #220 stone and creates a usable working edge.

Sharpening stone care
- Rinse the stone with clean water after use.
- Do not use detergents or aggressive cleaning agents.
- Allow it to dry slowly in a well-ventilated place away from heating and direct sunlight.
- Do not store it in water for extended periods.
- If the surface becomes dished, flatten it before the next sharpening session.
- Return the dry stone to its case.

Who is the stone suitable for?
SHAPTON Kuromaku #220 is suitable for more experienced home users, professional chefs, sharpeners and knife owners who need to repair a very dull or slightly damaged edge. It is also useful for adjusting the angle and creating a new sharpening bevel.
When should you choose a different stone?
If the knife is only normally dull and the edge is not damaged, start with #1000 grit. For more extensive repairs and larger chips, a #120 stone or professional sharpening may be more suitable. The stone is not intended for ceramic knives.

What is the #220 sharpening stone intended for?
It is used to restore a very dull edge, remove minor damage, adjust the angle and create a new sharpening bevel.
What is the difference between #120 and #220 grit?
The #120 grit removes material more aggressively and is suitable for more extensive repairs. The #220 stone provides better control during coarse sharpening.
Is #220 suitable for routine sharpening?
For a normally dull and undamaged knife, #1000 grit is more suitable. Use the #220 stone primarily for repairs and significantly dull edges.
Do I need to use a finer stone after #220?
Yes. We recommend continuing with at least #1000 grit, which removes the coarse marks and creates a usable working edge.
Does the stone need to be soaked before use?
The stone has low water absorption. Usually, wetting the surface is sufficient; if it dries quickly, it can be soaked briefly. We do not recommend leaving it in water for extended periods.
Can the case be used as a holder?
Yes, the plastic case can serve as a basic holder. Before sharpening, always check that it is stable and does not slip on the work surface.
Is the stone suitable for hard Japanese steels?
Yes. SHAPTON stones are also suitable for hard knife steels. However, use controlled pressure when sharpening fine blades.
Can ceramic knives be sharpened on the stone?
No. Ceramic knives require equipment designed specifically for sharpening ceramic blades.
When does the stone need to be flattened?
As soon as a hollow forms on the working surface or the stone is no longer flat. A flat surface is important for maintaining the correct edge angle.

SHAPTON – Japanese specialist in sharpening stones
SHAPTON Co., Ltd. is a Japanese manufacturer of synthetic sharpening stones and accessories for precise edge maintenance. The brand is known for fast abrasive action, a stable structure and a wide choice of grits for kitchen knives and craft tools.
SHAPTON is based in the town of Mashiko in Japan’s Tochigi Prefecture. The company focuses on developing sharpening stones that allow fast, controlled and highly repeatable edge work. Its products are used by professional sharpeners, chefs, craftspeople and home users who want to maintain their knives by hand.
SHAPTON sharpening stones feature a high concentration of abrasive particles and a carefully designed bonding system. This allows them to remove material efficiently, provide clear feedback during sharpening and wear more slowly than many softer stones. The wide grit range makes it possible to repair a damaged edge, create a new bevel, restore ordinary working sharpness and carry out extremely fine final polishing.
You can find the complete selection in the SHAPTON sharpening stones category.
Why are SHAPTON stones so popular?
Fast abrasive action
The high abrasive content makes it possible to restore the bevel effectively even on harder modern steels. With correct technique, there is therefore no need to apply heavy pressure to the blade.
No long soaking required
SHAPTON stones are designed for quick preparation. Before sharpening, the surface is usually only moistened with water, allowing you to start working without a long wait.
Lower wear
The optimised bonding system helps use the abrasive particles more efficiently. The stones therefore retain their working properties for a relatively long time, although their flatness still needs to be checked regularly.
Wide range of grits
From coarse repair stones to extremely fine polishing stones. Users can create a progressive sharpening sequence according to the condition of the knife, the steel used and the desired result.
Main SHAPTON sharpening-stone ranges
SHAPTON Kuromaku
Kuromaku is the classic range of solid synthetic sharpening stones. Individual grits are colour-coded, making it easier to distinguish between multiple stones while working. Each stone comes with a practical plastic case that can also be used as a base during sharpening.
SHAPTON GlassStone
The GlassStone range uses a thin abrasive layer firmly bonded to a glass base. The glass support provides dimensional stability and makes even a thin abrasive layer easier to handle. The extensive grit selection allows users to build a progression from basic sharpening to an exceptionally fine finish.
SHAPTON RockStar
RockStar is a modern premium range combining strong abrasive performance, a uniform structure and a finely controlled result. It is also designed for hard blades and users who want fast work without long soaking.
Which SHAPTON grit should you choose?
The brand or product range itself does not influence the result as much as choosing the correct grit. A coarse stone removes steel quickly, while a fine stone smooths the marks left by previous sharpening and refines the finished edge.
| Grit | Suitable use | Who it is suitable for |
|---|---|---|
| #120–#500 | Repairing a damaged edge, changing the bevel and working on a very dull knife. | More experienced users and repair sharpening. |
| #1000 | Restoring ordinary working sharpness and creating a new cutting edge. | The best first stone for most kitchen knives. |
| #1500–#3000 | Smoothing the bevel and providing a finer finish after basic sharpening. | Home cooks and more demanding users. |
| #4000–#8000 | Fine finishing and polishing of high-quality kitchen knives. | Japanese knives and blades requiring a smooth finish. |
| #12000–#16000 | Extremely fine specialised polishing after the previous stages. | Experienced sharpeners and specific edge-surface requirements. |
A simple recommendation for beginners
When buying your first sharpening stone, begin with #1000 grit. Add a #3000 stone for a finer finish. A coarse stone around #320 or #500 makes sense when the edge is damaged or significantly dull.
Maintaining SHAPTON sharpening stones
During sharpening, the working surface of every water stone gradually wears and may become hollow in the centre. An uneven stone makes it harder to control the angle and can result in an irregular bevel. It is therefore important to clean the surface continuously and flatten it when necessary.
- Moisten the stone before use according to the instructions for the specific range.
- Keep sufficient water on the surface while sharpening.
- Remove sharpening slurry and metal particles after use.
- Check the flatness of the working surface regularly.
- Allow the stone to dry naturally away from direct heat.
- Store the dry stone so that it cannot fall or suffer mechanical damage.
Holders, lapping tools, cleaning discs and other equipment can be found in the sharpening accessories category.
Would you like to learn how to sharpen correctly?
A high-quality sharpening stone is only part of the solution. Maintaining a stable angle, creating a burr, applying pressure correctly and progressing through the individual grits are equally important.

Where does the SHAPTON brand come from?
SHAPTON is a Japanese company based in the town of Mashiko in Tochigi Prefecture, Japan.
What makes SHAPTON sharpening stones special?
They stand out for their fast abrasive action, high abrasive content, good dimensional stability and wide choice of grits.
Do SHAPTON stones require long soaking?
Usually not. SHAPTON stones are designed for quick use after the surface has been moistened with water. Always follow the instructions for the specific product.
Which SHAPTON stone should I choose first?
For ordinary kitchen knives, #1000 is the most universal grit. It restores the working edge without removing material as aggressively as repair stones.
What is the difference between Kuromaku, GlassStone and RockStar?
Kuromaku stones are classic solid, colour-coded stones in a case. GlassStone uses an abrasive layer on a glass base. RockStar is a modern premium range with fast and even abrasive action.
Are SHAPTON stones suitable for hard Japanese steels?
Yes. A correctly selected SHAPTON stone can also be used on many hard Japanese steels. The appropriate grit, a stable angle and moderate pressure are decisive.
Can tools also be sharpened on SHAPTON stones?
Yes. Depending on the chosen range and grit, they can also be used to sharpen chisels, plane irons and other cutting tools.
Why does a sharpening stone need to be flattened?
The stone may wear unevenly during use. A flat surface improves angle control, blade contact and the consistency of the finished bevel.
