(10x) Japanese Natural Whetstone Asano Mikawa Nagura Tenjyo from Aich

https://ikkyu-japanavenue.online/

# # # # This listing includes 10 genuine Japanese *Mikawa Nagura Tenjyou* stones

Mikawa Nagura stones are among the most respected traditional Japanese sharpening stones and have been used for generations in the polishing and finishing of straight razors and other fine blades.

Tenjyou is one of the classic varieties of Mikawa Nagura, traditionally used to generate a fine slurry and refine the sharpening surface during the progression toward the final finishing stages.

Each stone is completely natural and unique in appearance, size, weight, and characteristics. These stones can be used to create slurry on compatible natural finishing stones and are particularly appreciated for razor sharpening.

This listing includes **10 individual Mikawa Nagura Tenjyou stones**.

Please note that, as natural stones, variations in color, shape, hardness, and texture are normal.

Please carefully check the photos, as they form part of the description.

Japanese Natural Whetstone Orange Kaisei -to ( Kazama ) 863g #3000 for Sword

https://ikkyu-japanavenue.online/

This is a very rare Japanese natural whetstone known as *Kazama-to*, originating from Yamagata Prefecture.

Yamagata is well known in the sword-polishing world for *Kaisei-to*. However, while *Kaisei-to* was the name commonly used within the sword-polishing industry, these stones were traditionally known locally as *Kazama-to*.

The Kazama-to quarry has long since closed, making genuine examples increasingly difficult to find. This particular stone was acquired from a collector.

During testing, the stone demonstrated a dense structure and produced a relatively fine slurry in moderate quantities. It is best used after a softer Kaisei-to and is particularly suitable for the later stages of *Sh*tajitogi*. It can produce a subtle and even luster on the edge.

As with all natural whetstones, each stone is unique and dimensions are approximate.
Please do not hesitate to contact me if you have any questions.

https://ikkyu-japanavenue.online/

# # # Il s'agit d'une très rare pierre à aiguiser naturelle japonaise connue sous le nom de *Kazama-to*, originaire de la préfecture de Yamagata.

La région de Yamagata est bien connue dans le domaine du polissage des sabres pour ses pierres appelées *Kaisei-to*. Toutefois, le nom *Kaisei-to* était à l'origine une appellation utilisée dans l'industrie du polissage des sabres, tandis que localement, ces pierres étaient traditionnellement connues sous le nom de *Kazama-to*.

Comme de nombreuses autres carrières de pierres à aiguiser japonaises, la carrière de Kazama-to est aujourd'hui fermée. Cette pierre provient d'une collection privée.

Lors des essais d'affûtage, elle a démontré une structure interne dense et produit une boue relativement fine, en quantité modérée. Elle peut être considérée comme une pierre à utiliser après une Kaisei-to plus tendre.

Elle est capable de donner au tranchant un lustre subtil et uniforme, ce qui la rend particulièrement adaptée aux dernières étapes du processus d'affûtage, notamment à la phase avancée du *Sh*tajitogi* (polissage préparatoire).

# # # Cette pierre n'est pas recommandée aux débutants.

Son utilisation demande une certaine expérience et une bonne maîtrise des pierres naturelles japonaises.

Chaque pierre naturelle étant unique, ses caractéristiques peuvent varier d'une pierre à l'autre. Les dimensions indiquées sont donc approximatives.

Il s'agit d'une pierre destinée aux passionnés et aux professionnels qui consacrent leur vie à l'affûtage et au travail des couteaux et des outils : une véritable pièce à conserver et à utiliser pendant de nombreuses années.

Japanese Natural Whetstone *Rare* Fine Bushu - to Grit #6000- #8000 412g Saitama
https://ikkyu-japanavenue.online/

Il s'agit d'une rare pierre à aiguiser naturelle connue sous le nom de *Bushu-to*, extraite dans la préfecture de Saitama il y a environ 70 ans.

Selon la tradition, ces pierres étaient extraites par des agriculteurs propriétaires terriens locaux pendant la période creuse des travaux agricoles. Aujourd'hui, les véritables pierres de Bushu-to sont devenues très rares sur le marché.

Bien que son apparence rappelle fortement celle de la pierre de Tsushima, la Bushu-to possède une texture plus fine, plus douce et plus raffinée.

Lors de nos essais, cette pierre a démontré une structure dense et très compacte, tout en produisant facilement une boue d'affûtage et en conservant un excellent pouvoir abrasif. Elle offre une sensation d'affûtage précise, douce et parfaitement contrôlée.

# # # La Bushu-to est particulièrement efficace comme pierre de transition entre les étapes d'affûtage moyen et de finition.

Elle élimine efficacement les fines rayures laissées par les pierres de grain moyen tout en affinant simultanément le tranchant et la surface du jigane (acier doux). En préparant efficacement la lame pour l'étape finale de polissage, elle permet de réduire considérablement le temps nécessaire sur la pierre de finition.

Japanese Natural Whetstone *Rare* Fine Bushu - to Grit #6000- #8000 349g Saitama

https://ikkyu-japanavenue.online/

# # # This is a rare natural whetstone known as *Bushu-to*, mined in Saitama Prefecture approximately 70 years ago.

It is said that these stones were traditionally mined by local landowning farmers during the agricultural off-season. Today, genuine Bushu-to stones are rarely encountered on the market.

Although its appearance closely resembles that of Tsushima stone, Bushu-to is known for its finer, smoother, and more refined texture. During testing, this stone demonstrated a dense and tightly compacted structure while still producing slurry readily and offering excellent abrasive power. It provides a precise, smooth, and finely controlled sharpening experience.

Bushu-to is particularly effective as a transitional stone between the medium and finishing stages. It efficiently removes the fine scratches left by medium-grit stones while refining both the cutting edge and the surface of the soft iron cladding.

By preparing the blade for the final polishing stage, it can significantly reduce the amount of time required on a finishing stone.

# # # 7 Asano Mikawa Nagura Atsu – Vintage Japanese Natural Nagura Set

This listing includes **7 genuine Asano-stamped Mikawa Nagura Atsu stones**, individually weighing approximately **150g to 300g**.

Atsu Nagura is traditionally used as part of the progression of Mikawa Nagura stones for razor sharpening and other fine sharpening applications. Known for its relatively dense structure and controlled abrasive action, Atsu produces a fine slurry that helps refine the edge while maintaining excellent stability and control.

These stones can be used with natural finishing stones to develop and condition the slurry, particularly for straight razors, woodworking tools, and high-quality knives. Each stone has its own individual character, as expected from genuine natural stones, while sharing the distinctive qualities associated with Asano-selected Mikawa Nagura.

The set offers a rare opportunity to acquire **seven Asano Mikawa Atsu Nagura stones in practical sizes ranging from 150g to 300g**. Whether intended for regular sharpening use, experimentation with different slurry characteristics, or collection, this group represents an excellent selection for enthusiasts of traditional Japanese natural sharpening stones.

As with all natural stones, each piece is unique in appearance, density, and sharpening characteristics.

Japanese Natural Whetstone Ozuku Asagi 760g Lv.4.5+ #10000 Kyoto

https://ikkyu-japanavenue.online/

This is a natural **Ozuku Asagi finishing whetstone** from Kyoto, Japan, with an approximate hardness of **Lv. 4.5** and an estimated grit of ** #10,000 or higher**.

The stone has the dense, fine abrasive structure characteristic of high-quality Ozuku finishing stones. Although firm and dense, it is not excessively hard or glassy, allowing the blade to engage comfortably with the surface while providing clear feedback and excellent control.

During sharpening, it offers ample cutting power and gradually produces a fine, refined slurry that develops the edge to a very high level of sharpness. Swarf releases readily from the surface, helping to minimize loading and making it easier to monitor the condition of the edge throughout the sharpening process.

The stone can be used effectively on its own, while a nagura may also be used to generate slurry more quickly and increase cutting speed. Adjusting the slurry allows the sharpening feel and finishing process to be tailored to the blade.

With its excellent balance of cutting ability, ease of use, and refined finishing performance, this Ozuku Asagi is particularly well suited for the final honing of straight razors, planes, chisels, Japanese kitchen knives, and Western-style knives.

Rare* Japanese Natural Whetstone Suisa-to Grit #2000+ /1204g from Wakayama

https://ikkyu-japanavenue.online/

**Suisa-to – Fine Natural Medium Whetstone from Wakayama**

A natural **Suisa-to** from Wakayama Prefecture, Japan.

While Suisa stones are commonly sold around #1000 grit, this particular example is noticeably denser and finer, with an estimated effective grit of approximately ** #2000+**.

It is particularly well suited for removing the scratches left by coarse stones while maintaining excellent cutting performance. Despite its appearance, the abrasive texture is much finer than expected.

During sharpening, slurry and metal swarf appear to gradually sink into the stone rather than accumulating heavily on the surface. The slurry does not excessively cling to the blade, making it easier to inspect the edge and monitor scratches during sharpening.

A versatile and interesting natural medium stone for knives, razors, woodworking tools and other edged implements.

After use, we recommend thoroughly cleaning the sharpening surface before storage.

A finer and more refined Suisa-to than the typical examples, offering excellent cutting performance and a distinctive sharpening character.

Japanese Natural Whetstone *Vintage* Narutaki Tomae 30' Size 1205g from Kyoto

https://ikkyu-japanavenue.online/

This is a **vintage natural finishing stone from Narutaki, Kyoto, Japan**, distributed during the middle of the Showa era (approximately 1950s–1970s).

Narutaki was historically one of Kyoto's important natural whetstone-producing areas. This stone retains its original **“Shohonyama Narutaki” (正本山鳴滝)** label and **“Betsusenhin” (別撰品 / Specially Selected Grade)** designation, indicating that it was carefully selected as a high-quality example. Stones retaining their original period labels have become increasingly rare today.

The stone has a dense, refined structure with well-balanced hardness and excellent cutting performance. During sharpening, it naturally produces a fine slurry without the need for a nagura, allowing the edge to be progressively refined toward an almost mirror-like finish.

Its precise and refined sharpening characteristics make it particularly suitable for the final finishing of straight razors, Japanese woodworking tools, and traditional Japanese kitchen knives.

Combining excellent finishing performance with the historical character of an authentic Showa-era stone, this vintage Narutaki is both a highly practical natural whetstone and a desirable collector's piece.

**Suisa-to – Fine Natural Medium Whetstone from Wakayama**

A natural **Suisa-to** from Wakayama Prefecture, Japan. While Suisa stones are commonly considered to be around #1000 grit, this particular example is noticeably denser and finer, with an estimated effective grit of approximately ** #2000+**.

Well suited to the medium sharpening stages of kitchen knives, razors, woodworking tools and other edged implements, it is particularly effective for removing scratches left by coarser stones while maintaining excellent cutting performance.

Although the surface initially appears quite dense, the stone has an interesting working character: slurry and metal swarf seem to gradually sink into the surface rather than accumulating on top. As a result, the slurry does not excessively cling to the blade, making it easier to inspect the edge and monitor scratches during sharpening.

Versatile and pleasant to use, this Suisa-to offers finer abrasive performance than its appearance might suggest.

After use, the sharpening surface should be thoroughly cleaned before storage.

As with all natural whetstones, each piece has its own individual characteristics. This stone is better suited to users with some sharpening experience who appreciate the unique behavior and character of traditional Japanese natural stones.
