When it comes to Japanese knives, one of the most important aspects to consider is the type of steel. This not only affects the durability and sharpness of the blade, but also its maintenance and the type of cut it can achieve. In this article, we will explore the most common types of steel in Japanese knives and their characteristics, to help you make the best choice based on your needs and preferences.
1. VG10 Steel: Versatility and Resistance
VG10 steel is one of the most popular in Japanese knife making due to its excellent edge retention and corrosion resistance . It is considered a high-end steel, with a balance between hardness and ease of sharpening. In addition, it is relatively easy to maintain, making it an ideal choice for both professional and amateur cooks.

Durability: High
-
Edge retention: Excellent
-
Maintenance: Moderate
2. AUS-10 Steel: Hardness and Performance
AUS-10 is another high-quality Japanese steel, similar to VG10 but slightly softer, making it easier to sharpen. This steel is well suited for everyday knives, as it offers good corrosion resistance and allows for a long-lasting, sharp edge. Its composition makes it less prone to chipping, making it ideal for those looking for a sturdy blade that doesn't require extensive maintenance.

Durability: High
-
Edge retention: Good
-
Maintenance: Low
3. Shirogami Steel (White Steel): Pure and Sharp
Shirogami or "White Steel" is known for its purity and ability to hold an extremely sharp edge. This type of steel, however, requires more careful maintenance due to its low resistance to corrosion. It is ideal for chefs looking for a sharp blade for precise cuts and who are willing to take good care of their knives.
-
Durability: Moderate
-
Edge retention: Excellent
-
Maintenance: High (requires immediate drying and care against oxidation)
4. Aogami Steel (Blue Steel): Strength and Longevity
Aogami, or “Blue Steel,” is an upgraded version of Shirogami, as it includes additional elements such as chromium and tungsten, which increases its corrosion resistance and hardness. This type of steel is an excellent choice for professionals who require a durable knife that will hold its edge, but with less maintenance required compared to Shirogami.
-
Durability: Very high
-
Edge retention: Excellent
-
Maintenance: Moderate
5. SG2 (R2) Steel: The Best Technology in Powdered Steel
SG2, also known as R2, is a high-end powder steel that offers the best in edge retention and durability. Thanks to its powder structure, it has a very fine grain that allows for an extremely sharp and long-lasting edge. It is an excellent choice for professional chefs who require a knife that can withstand intensive use without losing its edge quickly. However, it is usually more expensive due to its complexity in manufacturing.
-
Durability: Excellent
-
Edge retention: Superior
-
Maintenance: Low
How to Choose the Ideal Type of Steel?
The choice of the ideal steel depends on several factors:
-
Frequency of Use: If you use the knife daily and need a durable, easy-to-sharpen blade, VG10 or AUS-10 are reliable options.
-
Cutting preference: For those looking for extremely precise cuts, the Shirogami or Aogami are great options, but they require more maintenance.
-
Maintenance: If you prefer a knife that requires little maintenance, SG2 or AUS-10 steel might be best suited.
Conclusion
Choosing the right steel for your Japanese knife is an important decision that will affect both the performance and durability of the knife. If you are clear about the type of use you will be getting from it and the level of maintenance you are willing to put into it, you will be able to choose the steel that best suits your needs. Japanese knives offer a unique diversity in materials, each with characteristics that make them ideal for different types of chefs and cooking enthusiasts.
