What is the difference between steel and stainless steel? What is the steel material of the recommended kitchen knife?

Shirani steel is a traditional Japanese steel material that is characterized by its high hardness, sharpness, and ease of sharpening. Detailed features are given below.

1. Excellent sharpness: The white steel is described as having a fine particle structure and thus a sharp cutting edge that is easy to make and easy to sharpen. In addition, the sharpened blade is characterized by a sharp sharpness.

2. High hardness: White steel has a high carbon content, so the hardness is very high. Although the hardness is fixed depending on the kitchen knife and knife used, it is generally said that many are 65HRC or more. Therefore, it is said that there is little chipping of the cutting edge, and it is also excellent in durability.

3. Difficult spots are difficult to do: Due to its high hardness, white steel is supposed to be able to suppress dull spots from occurring.

Blue steel is characterized by its high hardness and sharpness with a carbon content of around 0.9%. It also has excellent durability by having dense crystals. Aoni steel is difficult to heat-treat and requires craftsmanship, making it an extremely expensive and rare steel material.

Blue steel is prone to rust and care is important because it contains a lot of carbon oxide. In addition, due to the high hardness, craftsmanship is also required for sharpening, but the sharpness is overwhelming, and it is so fun to cut. Aoni steel knives are very popular among professional chefs and knife enthusiasts.

Aoni steel and Shironi steel differ in properties such as hardness and durability.

Blue steel is characterized by its high hardness and sharpness with a carbon content of around 0.9%. It also has excellent durability by having dense crystals.
On the other hand, white steel is characterized by soft and easy to sharpen with a carbon content of less than 0.9%. In addition, it is easy to rust compared to blue steel, so care is important.

Which steel to choose depends on the intended use and preference. A big difference is in hardness and sharpness, so if you want to cut hard materials or cut finely, Aoni steel may be suitable, and if you want to cut soft materials or make simple cuts, Shironi steel may be suitable.

Damascus steel is one of the highest quality steels with a unique surface pattern. Detailed features are shown below.

1.高硬度：ダマスカス鋼は非常に硬く、高い耐久性があります。 So it can be used over time.

2.切れ味が良い：ダマスカス鋼は、硬度が高いため、非常に鋭い刃物を作ることができます。 Therefore, it is suitable for making cutlery such as a kitchen knife.

3. Beautiful pattern: Damascus steel has a unique pattern and is one of the features that makes it look beautiful. The patterns are created by stacking multiple layers of steel, repeatedly heating and forging.

4.腐食や摩耗に強い：ダマスカス鋼は、腐食や摩耗に強いとされています。 This is to ensure that the steel surface is subjected to a rust-proof treatment, such as oil or wax, to avoid excessive rust or layer peeling on the surface.

5. Uniform hardness: One of the characteristics of Damascus steel is its sharpness due to its uniform hardness due to its unique steel manufacturing method (stack tempering).

These are the main characteristics of Damascus steel.

V gold 10 is one of the steel materials for high-end Japanese kitchen knives. The features are detailed below.

1. High hardness V gold 10 is a steel material with a very high carbon content of 0.95% and extremely high hardness. The hardness is said to be around HRC60, and it can have a very sharp edge.

2. Highly durable V gold 10 has a very dense crystal structure, so it not only has high hardness but also excellent durability. When used as a kitchen knife, it can be used for a longer time because it can maintain its sharpness.

3. V-gold 10, which is not easy to rust, has a high content of chromium, which makes it difficult to rust. This is very important to extend the life of the kitchen knife.

4. V-gold 10, which is easy to process, has excellent workability, so that the cutlery with a beautiful and unique shape can be made by skilled craftsmen. Also one of the features is the ease of sharpening to better maintain the blade taste.

The above are the main features of V Gold 10.
