The progress of AUS-10 steel

In the world of steel, there are two types of steel that almost everyone is familiar with. If you take a look at the steel types used for the kitchen knives page, you will know some of them. One of the steels that have not been popular in the industry recently is the AUS-10. It is made by Aichi Steel of Tokai, Japan, AUS-10 due to its high carbon content. This is the most durable type in the AUS range.

Although the AUS-10 is still relatively unknown. Leading brand Sakai Takayuki, for example, has upgraded its Dumst 45-layer range with this high-quality steel. It's a pleasure to work with cool knives, why? A knife with a hardness of 60 HRC is extremely durable. As a result, it is easier to sharpen the cutting edge and maintain its sharpness.

Tough but flexible

The hardness of AUS-10 steel is mainly due to its high carbon content, about 1.05, and thus, the knives can be easily sharpened. It gives very fast results, but it also means that the knife is completely weak. That is why AUS-10 contains a certain amount of nickel, manganese, and silicon to improve the hardness and elasticity of the material.

Formation of carbide

This element is facilitated by vanadium. It is also a source of carbide. Carbide is a mixture of carbon and other materials such as vanadium, chromium, molybdenum, and nickel, and contact between these materials can only occur after prolonged exposure to extremely high temperatures.

Knives with high carbide content are faster than knives with less carbide content. Accelerating the rough carbide can destroy the carbide instead of accelerating it. This will give you (small) lumps on the tip, which is not the case with small pressed carbides.

Sharpening steel AUS-10

In addition, the combination of vanadium, chromium, and molybdenum also makes the steel resistant to wear and corrosion, so AUS-10 knives do not rust and do not need to be sharpened repeatedly.

If your AUS-10 steel knife slows down over time, you'll need other sharpening materials as well. For example, we do not recommend using a manual sharpener, however, you can use stiff rebar. If you have ever used a steel blade with hard carbide. This is an advantage when you do not have enough sharp knives and coarse sharp stones. You can read more about sharpening knives in our information section.

In general, we can conclude that in the future we may hear many stories about the power of AUS-10 steel. Very strong, corrosion-resistant, and wear-resistant. That being said, its excellent features allow us to consider it an advanced steel knife.
