Gin-san (Silver 3) - Gingami No.3
Gin San – Silver #3 – Gingami No. 3
Gin San is a premium Japanese stainless steel that combines a fine and extremely sharp edge, good corrosion resistance and enjoyable sharpening. Thanks to this balance, it is a popular material for both traditionally and modernly designed Japanese kitchen knives.
In the Dellinger range, you will find it in versatile Gyuto, Santoku and Bunka knives as well as more compact Ko-Santoku, Petty and Utility models.
One steel, several names
The names Gin San, Ginsan, Silver #3, Silver 3, Gingami No. 3 and GIN3 are used for the same type of Japanese knife steel. The material belongs to the YSS family of special steels originally manufactured by Hitachi Metals, now Proterial.
The name Gingami can loosely be associated with the expression “silver paper”. It follows the traditional Japanese naming system used for Shirogami, or White Paper Steel, and Aogami, or Blue Paper Steel. However, this does not mean that the steel is silver in colour or contains silver.
Gin San was designed to offer hardness and sharpness close to high-quality carbon steels while providing significantly easier protection against corrosion. This makes it attractive to cooks who want the traditional Japanese cutting character without the demanding care required by a reactive carbon-steel blade.

Stainless construction
The high chromium content makes maintenance significantly easier and reduces the risk of corrosion and unwanted patina.
Fine and sharp edge
The fine steel structure allows a precise edge to be created for clean cutting of meat, fish and vegetables.
Enjoyable sharpening
Compared with some more complex stainless steels, Gin San responds very well to water sharpening stones.
Balanced performance
It offers a good balance of hardness, edge stability, toughness and everyday usability.
Characteristics of Gin San steel
| Property | Characteristics | What it means in use |
|---|---|---|
| Steel type | Martensitic stainless knife steel | It can be hardened to a high hardness while also providing good corrosion resistance. |
| Material manufacturer | Proterial, formerly Hitachi Metals | It belongs to the Japanese YSS range of special tool and knife steels. |
| Knife hardness | Usually approximately 59–61 HRC | Good edge retention while maintaining reasonable toughness and sharpenability. |
| Edge retention | Higher | With correct use, the knife does not need to be sharpened too frequently. |
| Sharpening | Very good response to sharpening stones | A fine, clean and extremely sharp edge can be created. |
| Corrosion resistance | Good to very good | Maintenance is easier than with Shirogami or Aogami steels. |
| Typical use | Kitchen knives and scissors | Suitable for both versatile and specialised Japanese blades. |
The final hardness and properties of a particular knife depend on heat treatment, blade construction, geometry and grind. Therefore, always check the hardness range for the specific product.
Approximate chemical composition of Gin San
| Element | Typical content | Effect on steel properties |
|---|---|---|
| Carbon – C | Approximately 0.95–1.10% | Allows high hardness to be achieved and supports edge retention. |
| Chromium – Cr | Approximately 13.0–14.5% | Provides corrosion resistance and contributes to carbide formation. |
| Manganese – Mn | Small amount | Helps during heat treatment and influences the strength of the steel. |
| Silicon – Si | Small amount | Contributes to the strength and stability of the material. |
A simpler composition can be an advantage
Gin San does not use alloying as complex as some modern knife steels. Its relatively clean composition supports a fine structure, good edge stability and an enjoyable response during sharpening. This is why it is often sought after by cooks who want stainless steel with behaviour close to traditional Japanese materials.
Gin San is not carbon steel
Gin San is sometimes described as a “stainless alternative to carbon steel”. This comparison mainly refers to its ability to form a fine edge and its pleasant sharpening characteristics. Technically, however, it is a high-carbon stainless steel with a significant chromium content.
Unlike Shirogami or Aogami steels, it does not normally develop a reactive patina when cared for properly and is significantly less susceptible to corrosion. Nevertheless, we recommend washing it after use, drying it immediately and not leaving it in a damp environment for extended periods.
High-carbon does not mean carbon steel
The term “high-carbon” refers to a higher carbon content that makes it possible to achieve high hardness. Whether steel is considered stainless is determined primarily by its composition and sufficient chromium content. Gin San is therefore a high-carbon stainless knife steel.
Gin San compared with other Japanese steels
| Steel | Corrosion resistance | Sharpening | Character |
|---|---|---|---|
| Gin San / Silver #3 | Good to very good | Pleasant and easy to control | Stainless steel with a fine edge and traditional Japanese character. |
| Shirogami #2 | Low | Very pleasant | Pure carbon steel with a very fine edge and more demanding maintenance. |
| Aogami #2 | Low | Good | Alloyed carbon steel with higher wear resistance. |
| VG-10 | Very good | Slightly more demanding | Versatile stainless steel often used as the core of Damascus blades. |
| SG2 / SPG2 | Very good | More demanding | Powder metallurgy steel with very long edge retention and high hardness. |
The table describes the general character of the materials. The performance of a particular knife is always also influenced by heat treatment, blade geometry, grind and method of use.
Who is a Gin San knife suitable for?

How to care for a Gin San knife
Gin San offers significantly easier maintenance than traditional carbon steels, but a quality kitchen knife still requires proper handling. Stainless steel is not completely immune to staining and corrosion, especially during prolonged contact with moisture, salt or acidic ingredients.
- Wash the knife by hand using a soft sponge and ordinary dishwashing detergent.
- Dry it immediately after washing and do not leave the blade in water for extended periods.
- Do not use a dishwasher, as it can damage the edge, blade surface and handle.
- Cut on a wooden or high-quality plastic cutting board.
- Do not chop bones or frozen foods and do not use the knife for prying.
- Store the knife with the edge protected in a block, sheath or on a magnetic holder.
- Use water sharpening stones for sharpening with a grit appropriate to the condition of the edge.
Beware of hard and frozen ingredients
High hardness makes it possible to create a thin and extremely sharp edge, but it also requires more careful handling. Gin San knives are not designed for chopping bones, cutting frozen foods, prying or twisting the blade during a cut.

Frequently asked questions about Gin San steel
1. What is Gin San steel?
Gin San is a Japanese martensitic stainless knife steel that offers a fine edge, good hardness, corrosion resistance and enjoyable sharpening.
2. Is Gin San the same as Silver #3?
Yes. Gin San, Ginsan, Silver #3, Silver 3, Gingami No. 3 and GIN3 are different names for the same type of steel.
3. Does Gin San contain actual silver?
No. The name Silver or Gingami comes from the Japanese steel naming system and does not mean that the steel contains silver.
4. Is Gin San a carbon steel?
No. It is a high-carbon stainless steel with a significant chromium content. However, its sharpening behaviour and ability to form a fine edge can resemble carbon steels.
5. How hard is Gin San?
In kitchen knives, it is often approximately 59–61 HRC. The exact hardness depends on the heat treatment used by the individual manufacturer.
6. Is Gin San corrosion resistant?
Yes, it offers good to very good corrosion resistance. Nevertheless, we recommend washing the knife after use and drying it immediately.
7. Is Gin San better than VG-10?
Neither is universally better. Gin San is valued for its fine structure and enjoyable sharpening, while VG-10 uses a different alloy composition and often offers very good edge retention.
8. How do you sharpen Gin San?
It responds very well to water sharpening stones. For normal edge restoration, a medium-fine stone can be used, followed by a finer stone to refine the bevel.
9. Is Gin San suitable as a first Japanese knife?
Yes. It offers high cutting performance while requiring easier maintenance than traditional reactive carbon steels.
10. Can I wash a Gin San knife in the dishwasher?
We do not recommend it. A dishwasher can damage the fine edge, blade surface, bonded joints and natural handle materials.
