Code: SHA-50503HRProduct detailed description
Fine edge finishing and polishing
Japanese SHAPTON GlassStone JIS #6000 sharpening stone
A premium Japanese water stone for fine finishing, smoothing and polishing an already sharpened edge on quality kitchen knives.
SHAPTON GlassStone JIS #6000 is a fine finishing sharpening stone designed for an edge that has already been sharpened on a lower grit. It helps remove fine marks left by previous sharpening, smooth the bevel and create a very sharp edge with a clean and effortless cut.
The JIS #6000 grit with an abrasive-particle size of 2.45 μm is particularly suitable for quality European and Japanese kitchen knives with thin blade geometry. It follows a #2000 or #4000 stone well and provides a practical finish for users who want a finer edge without progressing to extremely high polishing grits.
The abrasive layer is mounted on a solid tempered-glass base. This limits flexing of the stone, supports the flatness of the working surface and provides a stable base for precise blade guidance. Thanks to its low water absorption, prolonged soaking is unnecessary – simply wet the stone with water before use.

Main advantages of SHAPTON GlassStone #6000
Fine finishing stone
JIS #6000 grit smooths the bevel and finishes the edge after previous sharpening on medium grits.
Cleaner and smoother cutting
A finely finished edge passes through ingredients easily, reduces crushing and allows precise cuts with less resistance.
For hard and high-quality steels
The consistent ceramic abrasive is also suitable for hard, stainless and highly alloyed steels used in Japanese knives.
Stable glass base
The tempered-glass base reinforces the abrasive layer, limits its deformation and makes precise edge guidance easier.
No prolonged soaking
Simply wet the stone with clean water before sharpening. It is quickly ready for both home and professional use.
What is JIS #6000 grit used for?
- fine finishing of an already sharpened edge,
- smoothing marks left by a #2000 or #4000 stone,
- light polishing of the bevel,
- removing a very fine burr,
- achieving a cleaner and smoother cut,
- thin and hard Japanese kitchen knives,
- quality European knives with fine edge geometry.
Where does the #6000 stone fit?
| Grit | Main use | Result |
|---|---|---|
| #120–#500 | Repairs and coarse sharpening | Restoration of a very dull or damaged edge |
| #1000–#2000 | Basic sharpening and working edge | Good cutting performance for everyday use |
| #4000 | Fine sharpening | Smoother bevel and cleaner cut |
| #6000 | Finishing and light polishing | Very smooth and finely finished edge |
| #8000 and above | Very fine to specialised polishing | Highly polished bevel for experienced users |
The #6000 stone finishes the edge; it does not create it
SHAPTON GlassStone #6000 is not intended for repairing chips, sharpening a very dull knife or creating a new bevel. Before using it, the edge must be correctly sharpened on a lower grit.
Recommended sharpening progression
| Knife condition | Recommended progression | Role of the #6000 stone |
|---|---|---|
| Very dull or damaged knife | #500 → #1000 or #2000 → #6000 | Final smoothing and polishing |
| Normally dulled quality knife | #1000 or #2000 → #6000 | Fine edge finish |
| Already sharpened knife | #4000 → #6000 | Smoothing the bevel and removing fine marks |
How to use the sharpening stone
- Inspect the edge. Before using the #6000 stone, the bevel must be properly established on a lower grit.
- Wet the working surface. Prolonged soaking is unnecessary.
- Secure the stone in a stable holder. It must not move or wobble during use.
- Maintain the original edge angle. Work precisely on the fine stone without unnecessarily increasing the angle.
- Use light pressure. Gradually reduce the pressure during finishing.
- Alternate both sides of the edge. Make the final strokes very lightly.
- After use, rinse the stone and allow it to air-dry.
Tip for the best result
Do not use heavy pressure on the fine #6000 stone. Guide the final strokes lightly and evenly. This reduces the risk of deforming the fine edge and helps remove the remaining burr.
Who is the #6000 stone suitable for?
We recommend SHAPTON GlassStone #6000 to users who already own a basic sharpening stone and want to add a fine finishing stage to their sharpening set. It is most beneficial for quality knives with thin blades and harder steel, where a finer edge finish makes a noticeable difference.
- quality Japanese and European kitchen knives,
- hard stainless, carbon and highly alloyed steels,
- thin blades and fine edge geometry,
- more experienced home users,
- professional chefs and sharpening enthusiasts,
- as a finishing stone after #2000 or #4000 grit.
Who is it not suitable for?
It is not ideal as the only sharpening stone for an ordinary household or for users who need to restore a very dull or damaged knife. In such a case, it is necessary to begin with a coarser or medium grit.

What is a JIS #6000 sharpening stone used for?
It is used for fine finishing, smoothing and light polishing of an already sharpened edge.
Can the #6000 stone be used on a dull knife?
Not as the first step. A dull knife must first be sharpened on a coarser or medium grit, and only then should the edge be finished with the #6000 stone.
Which stone should be used before #6000 grit?
A #2000 or #4000 stone is most commonly used. The exact progression depends on the condition of the edge and the desired result.
Is #6000 a suitable final grit for a kitchen knife?
Yes. It creates a fine, smooth and practical finish for quality kitchen and Japanese knives.
Does SHAPTON GlassStone require prolonged soaking?
No. Thanks to its low water absorption, simply wet the working surface with clean water before sharpening.
Is the stone suitable for hard Japanese steels?
Yes. The consistent ceramic abrasive is also suitable for hard and highly alloyed steels.
How much pressure should be used on the #6000 stone?
Use light pressure and reduce it further during the final strokes. Excessive force may reduce the precision of the edge finish.
Can ceramic knives be sharpened on the stone?
No. Ceramic knives require specialised diamond abrasive and an appropriate sharpening procedure.
Why is the abrasive layer mounted on glass?
Tempered glass increases stability, limits flexing of the abrasive layer and helps maintain a flat working surface.
How should the stone be cleaned after sharpening?
Rinse it with clean water, remove any remaining sharpening slurry and allow it to air-dry at room temperature.

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.
View the knife-sharpening course ›Frequently asked questions about SHAPTON
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.
