In the knife, the blade plays a paramount role, which should have the necessary parameters. It may be a kitchen or hunting model, but the main indicator of the quality of these products is steel. Cutting, anti-corrosion properties and much more depend on it. If you are careful about the material of the blade when choosing a knife, then the purchase will be successful.

Which steel is better for a knife

Steel characteristics determine the quality of such a tool. The material is an alloy of iron, carbon, additional elements are added to this composition to provide the necessary properties for the knife. The final result will also depend on heat treatment, hardening (finishing processes). In the manufacture of knife steel, thanks to the chemical composition, the blade acquires the necessary characteristics:

1. Hardness in foreign countries is designated “Hardness”. This value indicates the ability of the product to withstand loads, deformation due to external forces..
2. Wear resistance. The best steel for a knife has the ability to withstand wear during normal use (abrasion).
3. Strength (eng. – Toughness). Indicates the ability of the product to resist chips, cracks under severe loads..
4. Resistance to corrosion. Good products are able to resist rust and other corrosive effects from the environment. This property is often achieved by reducing other, more useful characteristics..
5. Sharpening ability.

Steel strength

All blades have certain characteristics. A high strength indicator indicates the ability of the product to maintain its integrity under heavy loads. Such a tool is reliably protected from cracks, chips. The same indicator indicates the ability of the blade not to break under a bend. As a rule, the strongest steel for a knife does not have the required hardness value.

Hardness of steel for knives

This is another main characteristic that affects the choice of tool for use in different conditions. In some situations, the blade must withstand the load under bending, and the hardness indicator is responsible for this property. This characteristic is achieved to the detriment of strength, therefore the hardest steel for a knife can be prone to chips or even crack under severe loads.

Wear resistance

The strongest steel has good resistance to wear during operation, abrasion. This also includes corrosion resistance, which prevents aggressive external factors from destroying the structure of the material. Wear resistance is often sacrificed in favor of other more important product properties. It is important to consider this parameter in cases when a hunting knife is selected, which often happens in a humid environment..

What steel do knives make

All knife steels are an alloy of carbon and iron in equal proportions. If you add more than the first element, it turns out tin, if the second – cast iron. When additional chemical elements (impurities and alloying) are added to the composition, the material gains special properties. As a rule, the following elements are used for this:

• carbon;
• chromium;
• manganese;
• molybdenum;
• silicon;
• nickel;
• tungsten;
• vanadium.

Types of steel for knives

When a person decides which steel is the best for knives, the names that have been heard many times in various adventure films – damask and damask come to mind. Unprecedented features are attributed to these two species, which are, as a rule, an element of folklore. For example:

1. Damask. It is often mentioned in epic stories about the heroes. The alloy has a complex composition of carbon and crystalline fractions of iron. It has a specific pattern on the surface, the fibrous structure of the metal. A damask knife, made according to all requirements, will be an excellent cutting tool, but not better than options from other types of metal.
2. Damascus. Another alloy surrounded by myths with a beautiful pattern on the surface due to the layered use of low and highly carbonized iron. Due to its structure, the composite has some viscosity, flexibility, and the ability to hold sharpening for a long time. The main advantage of products from this metal was a kind of pattern that could appear spontaneously with mixing layers.

Modern manufacturers often use powder composite, Japanese, carbon, stainless, Russian or Chinese steel. Each of these options has its own characteristics that determine the scope of the product and its price. It is impossible to say which type of material is the best, because their characteristics are used in different situations to achieve the desired effect..

What steel to choose for a knife

Each master or user himself determines which steel is the best for knives. This is due to the peculiarity of working on the material, its properties, characteristics or cost. There are several manufacturers and brands of steel, which among buyers are recognized as the most successful in terms of the combination of product properties. Check their rating below to choose the right product..

Steel grade for knives

There is a constant debate between masters and users over which steel for knives is considered the best, but according to consumer demand and reviews, such brands are considered popular and reliable:

1. M390 – stainless steel from the premium segment. It is resistant to wear, rust due to the presence of chromium in the composition. The best index of retention of sharpening and option among knife metals. It is very popular due to one of the cheapest product models with this brand – Benchmade Barrage.
2. ZDP-189 – material from the same segment. It has high hardness and acceptable ductility. Often used to create expensive knives from Spuderco, they use it in the manufacture of their best “limit” models.
3. CPM S35VN – An improved version of the famous S30V from Chris Reeve. To create it, a finer powder structure and the addition of niobium were used. It helped improve the ability to accept sharpening, strength.
4. ATS-34 – Japanese metal, a variant of the brand 154CM. These two varieties are similar in properties. High quality material with good sharpening retention. The disadvantages include less rust resistance than other options in this segment.
5. VG-10 – This metal is similar to that described above, but contains a large amount of chromium and vanadium, which makes it better. Often used for products under $ 100 from the Japanese company Spydreco.
6. 440C – material of the middle price segment, it is very popular among manufacturers. It contains a lot of chromium and carbon. Products from it are easily sharpened, not prone to wear, pitting (corrosion).
7. AUS-8 is a good grade Japanese alloy, rust resistant, but due to its lower carbon content it does not hold sharpening very well.
