1500 sharpening stone, Kuromaku SHAPTON K0707 blue
Code: SHA-K0707Product detailed description
Japanese SHAPTON Kuromaku JIS #1500 sharpening stone
A universal maintenance water stone for regular sharpening of kitchen knives and creating a fine, clean and practical working edge.
SHAPTON Kuromaku JIS #1500 is suitable for regular maintenance of normally dulled kitchen knives and for fine edge finishing after basic sharpening. It offers a balanced ratio between material removal and the resulting fineness, making it a practical standalone maintenance stone for home use.
Compared with #1000 grit, it works more finely, leaves a smoother bevel surface and removes less material. It is therefore suitable for knives that are not yet significantly dull but are beginning to lose their original cutting performance.
The hard structure of the stone helps maintain a flat sharpening surface and provides precise feedback while guiding the blade. The practical plastic case protects the stone during storage and can also be used as a basic stand while sharpening.

Why choose SHAPTON Kuromaku #1500?
Regular edge maintenance
The #1500 grit is suitable for knives that are slightly dull but whose edge is not chipped or significantly damaged.
Fine working edge
The stone restores cutting performance while leaving a finer finish than the basic #1000 grit. The resulting edge is suitable for everyday kitchen work.
Hard and slow-wearing stone
The hard construction of the Kuromaku range limits rapid dishing of the working surface and supports precise knife guidance at the desired angle.
Quick preparation for use
The stone has low water absorption. Before sharpening, it is usually enough to wet its surface and keep it moist during use.
When is #1500 grit the right choice?
- for regular maintenance of quality kitchen knives,
- for restoring a slightly dulled edge,
- for finer finishing after sharpening on a #1000 stone,
- for creating a smooth and easily controllable working edge,
- for hard Japanese and standard European knife steels,
- for users who do not want to remove unnecessary amounts of material during every maintenance session.
When is #1500 not enough?
If the knife is very dull, has minor nicks or requires a new bevel, start with a coarser stone. For a normally dulled edge, the SHAPTON Kuromaku #1000 is suitable. A damaged edge may require #220 grit or professional sharpening.

Difference between #1000, #1500 and #3000 grit
| Grit | Main use | When to choose it |
|---|---|---|
| #1000 | Basic sharpening | The knife is normally to significantly dull but has no major damage. |
| #1500 | Regular maintenance | The edge is only losing cutting performance and needs gentle restoration. |
| #3000 | Fine finishing | You want to refine the edge after previous sharpening and improve cutting smoothness. |
The #1500 stone can be used on its own for regular maintenance. If you want to refine the edge further, continue with a #3000 or higher grit stone. The complete range can be found in the SHAPTON Kuromaku sharpening stones category.
How to use the stone correctly
- Wet the working surface. The stone does not need to be left submerged in water for a long time.
- Ensure stability. The case can be used as a stand, but it must be stable and must not slip.
- Maintain a consistent angle. For standard kitchen knives, follow the original edge angle and blade construction.
- Use moderate pressure. The stone works efficiently, and excessive force reduces control.
- Sharpen both sides evenly. For single-bevel Japanese knives, respect their specific geometry.
- Keep the surface wet. Add a small amount of water as needed during sharpening.
- Rinse both the knife and the stone after sharpening. Dry the knife immediately and allow the stone to air-dry.
Would you like to learn the correct technique?
During the practical knife-sharpening course, you will learn to maintain the correct angle, create a burr, sharpen both sides evenly and progress safely through individual grits.
Care and storage
- Rinse the stone with clean water after use.
- Do not use detergents or aggressive cleaning agents.
- Do not leave the stone submerged in water for extended periods.
- Allow it to dry slowly at room temperature, away from heating and direct sunlight.
- Place only a completely dry stone in the case.
- If a hollow forms, flatten the working surface with a suitable flattening tool.
The necessary holders, flattening tools and cleaners can be found in the sharpening accessories category.
Who is the stone suitable for?
SHAPTON Kuromaku #1500 is suitable for home cooks, demanding users and professionals who maintain their knives regularly and do not wait until the edge becomes significantly dull. It works well as a standalone maintenance stone or as an intermediate step between basic sharpening and fine finishing.
Who is it not suitable for?
The stone is not intended for repairing deep chips, significantly damaged blades or sharpening ceramic knives. For larger repairs, use a coarser grit or professional sharpening.

Frequently asked questions
What is the #1500 sharpening stone suitable for?
It is intended primarily for regular maintenance of slightly dulled knives and finer edge finishing after basic sharpening.
Can #1500 be the only stone in the home?
Yes, provided you sharpen your knives regularly and do not allow them to become significantly dull. A coarser stone will be needed for very dull or damaged edges.
What is the difference between #1000 and #1500?
The #1000 stone removes material more quickly and is suitable for basic sharpening. The #1500 grit works more finely and is better suited to regular maintenance.
Do I need to continue with a finer grit after #1500?
No. The #1500 grit creates a functional working edge. Use a #3000 or finer stone if you want a smoother finish.
Does SHAPTON Kuromaku #1500 need to be soaked?
Not for an extended period. Thanks to its low water absorption, it is usually enough to wet the working surface and add water as needed during sharpening.
Is the stone suitable for hard Japanese knives?
Yes, it can also be used on hard Japanese knife steels. It is important to maintain the correct angle and avoid excessive pressure.
Can the plastic case be used as a holder?
Yes. The case can serve as a basic stand, but its stability and non-slip positioning should be checked before sharpening.
Is the stone suitable for ceramic knives?
No. Ceramic blades require special sharpening equipment intended specifically for ceramic knives.
How do I know when the stone needs flattening?
When a hollow forms on the working surface or the stone is no longer flat. A flat surface is essential 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.
