Steel K390 for knives: advantages and disadvantages of the alloy
K390 steel from the Austrian company Bohler is considered one of the best for making knives and other cutting tools. This is a tool powder steel designed for the production of stamping tools by the method of cold deformation. It is mainly used for the manufacture of folding and hunting knives.
For the production of kitchen knives, as a rule, it is not used due to the high cost. Knives of the highest price category are made from this metal. But, like other types of steel alloys, the material has its advantages and disadvantages.
Features of K390 alloy
K390 steel is characterized by increased hardness, strength and wear resistance. It is a high-speed steel with high viscosity and resistance to mechanical wear. The special chemical composition ensures the high hardness of the material, thanks to which the cutting edge of the blade retains its sharpness for the longest time, even during hard use.
At the moment, the brand is considered one of the best tool steels for cutting tools on the market. In the production process, a homogeneous carbide structure is formed, which guarantees maximum hardness and wear resistance.
It has the following chemical composition:
Carbon (C) – 2.5%. Provides hardness, wear resistance and viscosity. Due to the high carbon content, the edge remains sharp for a long time.
Chromium (Cr) - 4%. Increases density and tensile strength. Provides protection against corrosion, but in this case it is insignificant, since the chromium content is not high. Slightly increases hardness.
Molybdenum (Mo) - 4%. Increases strength, hardness and firing. Promotes corrosion protection.
Silicon (Si) - 0.55%. Deoxidizes steel and increases strength.
Vanadium (V) – 9%. Improves viscosity and strength. Increases resistance to abrasion and rust formation.
Tungsten (W) – 1%. Increases viscosity, strength and firing. Hardness does not change under the influence of elevated temperatures.
Cobalt (Co) – 2%. Increases hardness and strength. Allows hardening at elevated temperatures. Strengthens the positive properties of other elements.
The HRC indicator (hardness value on the Rockwell scale) of this metal varies in the range of 62-66 units. This is one of the best indicators on the cutting tool steel market. Thanks to this hardness, the cutting edge retains its hardness for as long as possible. At the same time, it is quite difficult to sharpen such a hard alloy with household tools.
The material is relatively expensive, so premium segment knives are produced from it. At the moment, steel provides the maximum possible resistance of the cutting edge to abrasive wear. At the same time, high chip resistance and good impact strength are maintained.
Advantages of K390 steel
The main advantages of the Bohler K390 alloy include:
- Increased resistance of the cutting edge to abrasive and other mechanical wear. The closest analogue in terms of this characteristic is the CPM 10V brand, which was previously considered a standard, but lost to K390 in other parameters.
- Increased impact strength due to the presence of a sufficient amount of molybdenum, tungsten and cobalt. According to this characteristic, the metal is 1.5 times higher than CPM 10V.
- Good flexibility for grinding and polishing. This allows you to remove deep risks and other stress concentrators from the surface. The blade and cutting edge can be given an almost mirror-like shine.
- Increased compressive strength. This allows you to make all kinds of stamps, dies, tape knives and other parts.
- Resistance to chip formation. This ensures reliability and a long service life of finished products.
- Homogeneity of the structure. Due to this, the characteristics are stable over the entire area of the blade.
- High hardness - 62-66 HRC. Even with intensive and hard use, the sword remains sharp for a long time.
- Resistance to overheating during heat treatment. Steel withstands long-term heat treatment without deterioration of properties, which guarantees high-quality hardening and calcination.
- Possibility of making blades by forging method. This allows craftsmen to make unique collector's items.
- The possibility of additional improvement of working characteristics in the process of manufacturing finished products. For example, some manufacturers perform additional heat treatment using repeated thermal cycling and cryogenic treatment.

Disadvantages of the alloy
Despite the huge number of positive characteristics, the material has some disadvantages:
High cost. Knives of the highest price category are made from this steel. It is used by large manufacturers. Although some private craftsmen produce products from this alloy in small batches. For the production of kitchen knives, as a rule, enyaets is not used.
Low resistance to corrosion. The composition contains quite a lot of carbon and little chromium, so the material can rust. This is a kind of payment for maximum hardness. Therefore, the knife requires proper and regular maintenance.
It is quite difficult to sharpen the edge yourself. The steel is very hard, so it is difficult to sharpen. To do this, you need to use special sharpening tools, such as diamond and elbor blocks. The complexity of sharpening is one of the secondary factors of the high cost of finished products.
Risk of injury. When sharpened with a knife, it is very easy to cut yourself, so you should work with it carefully.
Small selection of models. Only a few large manufacturers and private craftsmen make knives from this alloy. At the moment, the company offers the largest number of models
Conclusions and recommendations
Steel K390 is deservedly considered one of the best tool alloys on the market for the production of cutting tools. However, products made of this material cannot be called a good choice for every person. Knives with K390 blades are quite expensive, and the selection of models is small.
Large companies produce products in small batches, and individual craftsmen often produce only to order. Therefore, such products can be recommended to professionals who are familiar with steels and the peculiarities of their operation. Such a blade must be properly cared for, otherwise it can become covered with rust and pitting, which often affects not only the appearance, but also the performance characteristics.
The K390 knife should be used carefully, as a damaged edge will be expensive to restore due to the difficulty of resharpening. Otherwise, K390 is an excellent powder steel for making premium quality knives.

MAMMOTH TEETH HANDLE MATERIAL Mammoth tooth.
A mammoth tooth is a product of animal origin. Its exceptional feature is the fact that its source is extinct animals - mammoths. Paleontologists found that they lived on Earth about 10 thousand years ago, and their number was very large. The teeth of mammoths were not permanent and changed about four times during their lifetime. Fallen teeth, which modern scientists find during excavations, and become the basis for decorative elements, among which there are knife handles.
Due to a long stay in the soil, the material acquired a very unstable structure - the enamel became rock-hard, and the dentin, on the contrary, became loose. But modern material stabilization technologies have helped turn mammoth teeth into an excellent basis for creating luxurious knife handles. The polymer composite provides products with resistance to corrosion and moisture, and the natural base gives a unique texture and intricate pattern.
