5000 sharpening stone, Kuromaku SHAPTON K0704 burgundy
Code: SHA-K0704Product detailed description
Japanese SHAPTON Kuromaku JIS #5000 sharpening stone
A fine finishing water stone for smoothing the sharpening bevel, removing marks left by previous sharpening and creating an exceptionally fine, precise edge.
SHAPTON Kuromaku JIS #5000 is a fine Japanese sharpening stone intended for the final stage of sharpening high-quality kitchen knives. It follows a basic or medium-fine stone, smooths the bevel surface and helps create a clean edge with a smooth cutting action.
The #5000 grit is not intended for repairing a dull or damaged knife. Its purpose is to refine an edge created on a lower grit, remove more pronounced sharpening marks and improve cutting precision. It performs best after a #1000, #1500 or #3000 stone, depending on the condition of the knife and the desired result.
The hard structure of the stone supports precise blade guidance and slow wear of the working surface. The practical plastic case makes storage easier and can also be used as a basic stand during sharpening.

What do you gain by finishing the edge on #5000 grit?
Finer bevel surface
The stone smooths deeper marks left by previous sharpening and creates a more even edge surface.
Smoother and more precise cutting
A finely finished edge passes through ingredients more easily and is suitable for precise slicing of vegetables, boneless meat, fish and herbs.
Gentle finishing of quality knives
The fine grit removes only a small amount of material and allows controlled finishing of hard Japanese and European knife steels.
Hard stone with low water absorption
The stone is quickly prepared, wears slowly and, with proper care, retains a flat working surface for a long time.
Important: #5000 does not replace a basic sharpening stone
A dull knife cannot be restored efficiently on a fine #5000 stone. First create a sharp, continuous cutting edge on a suitable lower grit. Use the #5000 stone only as the final finishing step.
What applications is the stone suitable for?
- final refinement of kitchen knives,
- removing marks left by lower-grit stones,
- hard Japanese and high-quality European knife steels,
- fine Santoku, Gyuto, Nakiri, Petty and Sujihiki knives,
- precise slicing of vegetables, boneless meat, fish and herbs,
- experienced home users and professional chefs,
- finishing selected carving and woodworking tools.

How to build the correct sharpening progression
| Grit | Task | When to use it |
|---|---|---|
| #220 | Coarse repair | Very dull edge, minor chips or adjustment of the bevel angle. |
| #1000 | Basic sharpening | Creating a new working edge on a normally dull knife. |
| #1500 to #3000 | Edge refinement | Smoothing coarse marks and preparing the edge for fine finishing. |
| #5000 | Fine finishing | Final smoothing of the bevel and creation of a fine edge. |
For most high-quality kitchen knives, a practical combination is the SHAPTON Kuromaku #1000 for creating the edge and #5000 for fine finishing. For a smoother progression, you can add the SHAPTON Kuromaku #1500 or a #3000 grit stone between them.
A mirror polish is not the only measure of sharpness
SHAPTON stones may leave a very fine matt surface on the bevel. This is not a sign of a poor result. Even geometry, complete burr removal and a clean cutting edge are more important to the knife’s performance than the appearance of the bevel alone.
How to use SHAPTON Kuromaku #5000
- First create a sharp cutting edge on a lower grit.
- Wet the surface of the stone with water. Extended soaking is neither necessary nor suitable.
- Secure the stone in a stable position. The case can be used as a stand, but it must not slip on the work surface.
- Maintain the same sharpening angle as during the previous sharpening stage.
- Use very light pressure. During the final strokes, work almost entirely with the weight of the knife.
- Alternate the sides of the edge regularly to keep the bevel even.
- Remove the remaining burr with several very light strokes.
- Rinse and immediately dry the knife and check the result before use.
Learn how to progress through the individual grits
During the practical knife-sharpening course, you will learn how to create a new edge, safely remove the burr and recognise when it is time to move to a finer sharpening stone.
Care of the polishing stone
- Only wet the stone before use; do not soak it for extended periods.
- Keep the surface wet with clean water while working.
- Rinse the stone after sharpening without using detergent.
- Allow it to dry slowly at room temperature.
- Do not dry it on a heater, in direct sunlight or with hot air.
- Place only a completely dry stone in the plastic case.
- If the surface becomes dished, flatten the stone before the next use.
Suitable holders, flattening tools and cleaners can be found in the sharpening accessories category. The complete range can be found among the SHAPTON Kuromaku sharpening stones.
Who is the stone suitable for?
SHAPTON Kuromaku #5000 is suitable for demanding home cooks, professionals and users of high-quality Japanese knives who have already mastered basic sharpening and want to refine the edge further. It provides the greatest benefit on precise kitchen knives with thin geometry and high-quality steel.
Who is it not suitable for?
The stone is not suitable as the only sharpening stone for dull or damaged knives. It is not intended for removing chips, substantially changing the sharpening angle or sharpening ceramic blades.

Frequently asked questions
What is the #5000 sharpening stone intended for?
It is used for fine edge finishing, smoothing the sharpening bevel and removing marks left by lower-grit stones.
Can a dull knife be sharpened on the #5000 stone?
Not efficiently. A dull edge must first be restored on a basic stone such as #1000. The #5000 stone is intended for final finishing.
Which grit should be used before the #5000 stone?
A practical choice is #1000, #1500 or #3000. The correct progression depends on the condition of the edge and the desired fineness of the result.
Is #5000 suitable as the final stone?
Yes. For most high-quality kitchen knives, #5000 grit provides a very fine and practically useful finish.
Will the #5000 stone create a mirror polish?
It can significantly refine the bevel surface, but the result may not be a perfect mirror polish. Functional sharpness is not determined solely by the appearance of the bevel.
Does SHAPTON Kuromaku #5000 need to be soaked?
No. SHAPTON polishing stones have low water absorption and only need to be briefly wetted before use. Extended soaking may damage the stone.
Is the stone suitable for hard Japanese knives?
Yes. It is also suitable for hard Japanese knife steels, provided that the edge has first been properly created on a lower grit.
Can the case be used as a holder?
Yes. The plastic case can serve as a basic stand, but its stability should be checked before sharpening.
Is the stone suitable for ceramic knives?
No. Ceramic knives require sharpening equipment intended specifically for ceramic blades.
How do I know when the stone needs flattening?
Flatten the stone as soon as a hollow appears on its working surface or it is no longer flat.

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.
