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.

How much is a walrus tusk today

What is the real price for a walrus tusk, the cost of which is often unclear to the average man in the street? How not to get into trouble by reacting to ads with the headings “buy a walrus tusk” or “buy a walrus tusk”, how to find out how much a walrus tusk really costs? To get reliable answers to these questions, it is worth studying the modern demand for such a rare item as walrus tusks, the price of which is significantly determined not only by size, but also by other factors. Considering these recommendations, you can count on the most advantageous offer that those who wish to buy a walrus tusk can give.

It is worth knowing that the walrus tusk, which you would like to sell, must have maximum integrity, then its value will meet your best expectations.
When selling, be guided by the current exchange rate, which significantly affects how much a walrus tusk will cost, its price is formed taking into account exchange rate fluctuations.
The competence of the experts who make the assessment is very important in this matter: not every advertisement “I will buy a walrus tusk” is actually supported by professionals, so you need to be careful and careful when choosing a buyer.

Walrus tusk products

Hunters for rarities seek to buy a walrus tusk not only in its original form, souvenirs and crafts, the material for which is a walrus tusk, are no less popular and in demand, their cost can also reach a decent amount, especially if these are antiques. The natural appeal of tusks, their particular color and structure, embodied in art objects, create a special atmosphere of luxury in any room. This makes tusk crafts a unique, status gift, relevant at all times, capable of becoming a value, even inherited. Most often there are crafts made by the inhabitants of the peoples of the North, reflecting their life and way of life:

• walrus tusk handled knives are very expensive and popular among collectors and hunters

• group and single animalistic images (bears, seals, deer);
• sculptures depicting harness dogs;
• images of people engaged in characteristic activities, such as a hunter;
• deity images.

The walrus is a very large animal with thick, wrinkled skin. Males have large skin growths on the neck and shoulders. The larger these growths, the more attractive they seem to females. The thickness of the skin reaches 10 cm, and subcutaneous fat - 15 cm. Males are much larger than females - the weight of some individuals reaches 2 tons, but usually does not exceed 800 - 1500 kg. Females weigh on average 500 - 800 kg. The length of adult walruses is 2 - 3.5 m.

Young walruses have dark brown skin with yellowish hairs. Adult animals "bald" over time, and their skin acquires a lighter shade. Old individuals become almost pink towards the end of life.

A distinctive feature of these pinnipeds is their huge tusks. Their length can reach 1 m. They help the animal when moving on a slippery surface and for breaking through ice. The tusks are elongated upper fangs pointing down. In males, they are larger and are used for battles with other males during the mating season. Males with the largest tusks dominate the herd.

The muzzle is wide, with hard thick antennae-setae on the upper lip. The eyes are small. The ear holes are hidden under the skin and do not have an exit to the outside. The tail is small. The front flippers are well developed, allowing walruses to move more or less normally on land, unlike many other pinnipeds that can only crawl on land.

There are three populations of walruses with slight external differences - the Pacific, the Atlantic and the population of the Laptev Sea.

The Pacific walrus population is the largest both in terms of numbers and size of animals. It lives on the northern coast of Eastern Siberia, on Wrangel Island, in northern Alaska. In winter, herds of walruses move south - to the Bering Sea, to Kamchatka and to the southern coast of Alaska. According to modern estimates, the population is 200 thousand animals.

The Atlantic walrus is about a third smaller than its Pacific relatives. It lives in the north of Canada, Greenland and in the western region of the Russian Arctic. It was almost completely exterminated by man as a result of uncontrolled fishing. Estimated population size - 15 - 20 thousand individuals.

The Laptev walrus population is the smallest - about 5 thousand individuals. It is isolated from other populations in the Laptev Sea and the Kara Sea.

The state of the population and the relationship with humans
In the 18-19 centuries. commercial fishing for the Atlantic walrus has led to the almost complete extinction of this animal. Currently, hunting for it is prohibited everywhere, but some indigenous peoples of the north are allowed to hunt a small number of walruses, but necessarily for their own consumption, with a ban on the sale of meat, fat or bones of the animal. For European walrus meat dishes do not seem tasty, but cooked walrus tongue is considered a delicacy.

Chukchi, Yupik peoples (Russian Far East) and Inuit (North America) consume walrus meat all winter, flippers are canned and stored until spring, tusks and bones are used to make various tools, amulets and jewelry. Waterproof thick skin - for finishing houses and boats. Modern, cheap building materials are available in the far north, and walruses no longer play as important a role in survival as they did 100 years ago, but they still remain in demand for many indigenous peoples, and walrus skin carving and beading is an important art form.

Walrus populations are difficult to determine. The fertility of animals and their mortality are not fully understood. Complicates the calculation and difficult climatic conditions of the habitat of walruses. The Pacific walrus is currently classified as "endangered" by the Endangered Species Act. The Atlantic walrus and the Laptev population are listed in the Red Data Book of Russia and are assigned to the second (decreasing in numbers) and third (rare) groups of rarity, respectively.

The effects of global warming are another area of concern for zoologists. The volume and thickness of pack ice (at least 3 meters thick and older than 2 years) is constantly decreasing, which affects the birth rate of animals and the disappearance of habitual habitats.

According to various estimates, the number of all walrus populations is 200-250 thousand heads.

• During the last ice age, walruses were distributed up to 37 degrees north latitude. This is evidenced by the found remains, dated at the age of 28 thousand years. near San Francisco in the USA. At the same latitude is the northern border of the African continent, Greece, Japan, Turkey.
• Despite their large size, walruses are sometimes attacked by killer whales.
• In a strong current, walruses cling to the edge of the ice with their tusks, holding under water. They also help animals climb high ice. This use of tusks has given walruses the generic name Odobenus rosmarus, which is Greek for "tooth walker".
• The stomach of the walrus is so large that the peoples of the north made themselves waterproof capes from it.
• In cold water, the blood vessels of the animal are greatly reduced, which makes the skin of the animal almost white.

 Ironwood - iron wood - handmade knives

Ironwood - Ironwood

In nature, ironwood is extremely rare, so it occupies an honorable place in the Red Book. However, in its properties, each iron tree is not inferior to the density of cast iron. Its bark can withstand fire from firearms, but at the same time it sinks hopelessly in water. It should be noted that this is not a separate class of trees, but a whole group collected from different species. It includes several dozen species of plants with unusually dense wood. They can be found on every continent. Moreover, raw materials are used both in the industrial industry and in medical practice.

What's special about these trees?

It is quite difficult to recognize the “stone” species of a perennial plant with the naked eye. Especially if they are on the verge of extinction. However, they are characterized by the following features:

• the age of such centenarians is at least 2 hundred years;
• wood fiber is resistant to corrosion processes and does not deteriorate under the influence of strong acids;
• the bark contains many tannins that protect their “hosts” from all kinds of parasites, as well as from rot fungus;
• the log will definitely go under water, since the density of the wood is 1 t/m³, taking into account the humidity of 12%, for this reason such species grow quite slowly;
• the height of each exceeds 25 meters, and the girth of the trunk reaches more than 200 cm.

All these properties are necessary for ironwood to survive in the harshest climatic conditions. Sudden temperature changes in Russia, African drought or humid European climate cannot harm this natural phenomenon. These types of trees adapt well to any unfavorable environment. To do this, they are equipped with a considerable number of devices, ranging from the unique structure of the trunk/roots to the chemical composition of the bark. In this regard, they are widely used in production:

• furniture;
• building structures;
• cars;
• cosmetics;
• decorative elements;
• underwater technology

Asian water buffalo horn

Asian buffalo

This is one of the largest animals belonging to the bovine family. The body length reaches 3 m, the height at the withers is 2 m. Large males can weigh a ton or even more. The horns of these animals are in the form of a crescent moon, directed in different directions and slightly back.

The color of animals is gray. The wool is thin and moderately long. It forms a small bundle on the forehead. The body of this animal is massive, powerful, the limbs are strong and muscular. The hooves are large and forked.

The head resembles a bull, has a more massive cranial part. Eyes and ears are small. The tail is thin, long, with an elongated tuft of hair below.

African buffalo

It is slightly smaller than its Asian relative. Its height is up to 1.8 m at the withers, its body length is 3 m. It weighs a little less.

African buffalo has a black or dark gray color. This animal has pronounced sexual dimorphism: females are much smaller than males. Females also have a less powerful physique. Their horns are shorter and thinner.

The African buffalo has unique horns. Their bases in adults are fused, forming a shield made of bones. It is so strong that it cannot be pierced by a bullet from a rifle. The horns at the base diverge to the sides, bend down, and then go up and inward with the same smooth curve. Young individuals do not have such a horn shield.

The African buffalo has very poor eyesight. It receives information from the surrounding world thanks to a highly developed sense of smell and hearing.

In a normal environment, the animal roars and snorts. In extreme circumstances, he moans loudly.

Lifestyle

Buffalo graze at night. He spends the day in the shade of a tree, in a swamp, where the temperature is lower. He is sleeping or chewing gum. Often a puddle or a pit can be a refuge from the heat. He needs a daily drink of water. During the day, the animal needs up to 40 liters of water. In this regard, the buffalo never moves further than 4 km from the water.

Females with calves are especially responsive. They are constantly alert, show their concern. When alarmed, the buffalo raises its head and throws down its horns. The sound is quiet enough for the herd to flee from danger. In case of serious danger, animals can develop a speed of more than 50 km/h.

Buffaloes are reluctant to enter the water. However, they swim well.

Habitats of the buffalo

Even in the 19th century, this animal was often found in sub-Saharan Africa. Today, the buffalo population can be found in South and East Africa, where human intervention in the biosphere is the least noticeable.

Buffalo can live in the savannah, tropical forests, mountains (up to a height of 3 km). The animal feels best in the savannas, where there is access to drinking water and juicy feed all year round. A buffalo does not live far from water bodies. Due to human extermination, the animal is most attached to protected areas: there you can meet herds of hundreds of individuals.

Demeanor

In the north of Tanzania, there is a national park near Lake Manyero. It is here that the largest population of these herbivores is found. Animals are attracted by the spacious pastures located in the green zone between the lake and the mountain slopes. Some adult bulls do not connect their lives with the laws of the herd, preferring an independent existence. The large size and large strong horns are reason enough to feel safe.

Important decisions for the herd are made by high-ranking females, and controversial issues are resolved in the form of a special form of voting. Closer to noon, the herd settles down to process the morning feed. Sometimes the leading females raise their legs, turning in the direction, while the others closely follow them. As a result, the line moves further in the direction chosen by "the majority of those who voted".

At this time, it is time for procedures related to personal hygiene. The local species of woodpeckers and herons are happy to provide their skin-cleaning services in exchange for insects gathering under the wool. In this way, the birds help the buffalo to regulate populations of parasitic insects that can carry disease-causing microbes. The immune system of an adult buffalo allows you to cope with almost all common diseases. However, weakened individuals can become victims of parasites.

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.
