Powder steel M398
BOHLER M398 MICROCLEAN powder steel is a new martensitic steel from the Swedish-Austrian concern Bohler-Uddeholm, which was developed and launched in 2019. The increased content of Chromium provides it with good corrosion resistance, and the increased content of Vanadium provides the steel with extremely high wear resistance. The Carbon content has increased by 30% compared to its predecessor M390 steel and added to its hardness, which is 63-64 units on the Rockwell scale. To date, M398 steel is considered one of the best powdered stainless steels, which speaks for itself not only in its characteristics, but also in its price, which is quite high. Accordingly, be prepared for the fact that the cost of the finished knife cannot be low.

Powder steel M398 is produced in accordance with European standards and has the following chemical composition and microstructure (we will consider in comparison with the predecessor steel grade M390):

• Carbon (C, Carbon): is one of the main parts of the steelmaking process, improves edge retention and increases toughness; increases hardness and wear resistance.
• Silicon (Si, Silicon) and Manganese (Mn, Manganese): used as standard deoxidizers and degasifiers to remove oxygen during metal melting, increase strength.
• Chromium (Cr, Chromium): increases corrosion resistance (at >11% it makes the alloy stainless), enhances hardness and density.
• Molybdenum (Mo, Molybdenum): increases hardness, strength, hardenability and density; improves machinability and corrosion resistance.
• Vanadium (V, Vanadium): increases strength, wear resistance, increases density and viscosity; increases corrosion resistance by increasing the oxide film; vanadium carbide inclusions are very hard. The presence of this metal in steel indicates its quality.
• Tungsten (W, Tungsten): is the most refractory metal of all, used to add strength and toughness, improve hardenability; retains hardness at high temperatures.

Due to the higher amount of primary carbides in M398 steel (about 30 vol.%), the hardness, wear resistance and compressive strength in M398 increase significantly.

Also, steel M 398 is characterized by the following properties:

• - high level of corrosion resistance;
• - high strength;
• - extremely high wear resistance;
• - high stability during heat treatment;
• - good grindability;
• - good polishability;
• - high hardenability and compressive strength.

Thus, the knives made of M398 powder steel, the exclusive knife.net.ua manual robotic knives, are highly durable and can withstand fairly large loads and at the same time maintain their sharpness perfectly. They have excellent anti-corrosion properties and do not react with most alkalis and acids, that is, these knives do not require special care, which makes them a huge plus when used in nature, hunting, fishing and / or in extreme conditions *. Perhaps the only disadvantage of knives made of M398 steel is their cost, which is quite high and one must be prepared for this.

It is worth remembering that if you use the knife for its intended purpose and handle it with care, the knife will serve you for a very, very long time.

Ironwood - iron wood - handmade knives

In nature, ironwood is extremely rare, therefore it occupies an honorable place in the Red Book. However, in terms of its properties, each iron tree is not inferior to the density of cast iron. Its bark can withstand gunfire, but it sinks hopelessly in water. It is worth noting that this is not a separate class of trees, but a whole group assembled 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 is special about these trees?

With the naked eye, it is quite difficult to recognize the "stone" breed of a perennial plant. Especially if they are on the verge of extinction. However, they are characterized by the following features:

• the age of such long-lived people is not less than 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 the rot fungus;
• the log will definitely go under water, since the density of wood is 1 t / m³, taking into account the humidity of 12%, for this reason, such breeds 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 an iron tree to survive in the harshest climatic conditions. Sharp temperature changes in Russia, African drought or humid European climate will not be able to harm this natural phenomenon. Such varieties of trees perfectly adapt to any adverse environment. For this, they are equipped with a considerable number of devices, starting from the unique structure of the trunk / roots and ending with the chemical composition of the bark. In this regard, they are widely used in production:

• furniture;
• building structures;
• cars;
• cosmetics;
• decorative elements;
• underwater equipment.

HANDLE MATERIAL - MAMMUT TOOTH

Mammoth tooth is a rare raw material used to make decorative items, such as knife handles, pistol grips, and jewelry. This is a unique natural element, which can be obtained infrequently, so its cost is quite high.

Today, a mammoth tooth, after a certain processing (stabilization), is widely used by master knifemakers. Stabilization is the process of polymerizing a material under vacuum with or without fat-soluble dyes, while the material is impregnated with polymeric substances through and through.

HANDLE MATERIAL MAMMUT TOOTH

Mammoth tooth is an ornamental material 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 lives. Fallen teeth, which modern scientists find during excavations, become the basis for decorative elements, among which there are knife handles.

Due to the long stay in the soil, the material acquired a very unstable structure - the enamel received stone hardness, and the dentin, on the contrary, became loose. But modern material stabilization technologies have helped turn mammoth teeth into an excellent base 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.

Material Features

Mammoth molars are used to create a variety of products. Outwardly, they look like elephant teeth, but they are much larger and have a different shade. Given the historical value and rarity, the mammoth tusk is especially highly valued, since this animal died out long before our era. The tusks of prehistoric giants can be found not only in paleontological museums, but also on the shelves of jewelry stores, they are used to decorate the interior, they are used to create various decorative elements - of course, not in their original form, but in a processed one.

The age of the material, according to scientists, is 10-40 thousand years. How mammoths lived is not fully understood to date. However, the remains of these giants found by scientists, their bones, teeth, even whole carcasses, allowed scientists to make serious progress in this area of ​​research. The available data made it possible to find out what the appearance of mammals was, what they ate, in what climatic conditions they lived, what kind of behavior they had (for example, they led a herd or solitary existence).

The mammoth ate almost the same as the modern elephant: its diet was plant foods. In the modern world, an animal could eat coniferous plants. They preferred roughage, which they chewed without difficulty with their strong jaws and teeth like large plates. An interesting feature of the mammoth organism was that as the old tooth wore out, a new one grew, which displaced the old one and took its place. Thus, the animal could change its teeth several times in a lifetime. Completely all the teeth changed in about a ten-year interval, and the average life expectancy of a mammoth was 40 years. In other words, one animal could survive on average four complete changes of molars. It is due to this feature that people often find individual worn-out mammoth teeth, but do not meet other traces of it.

Appearance

If you look at the tooth of a mammoth, you can see a heterogeneous surface with ribbed edges. Bone, enamel and soft tissue alternate in this case. The material has a rather complex structure:

its basis is dentin.

The dentin layer is covered with a protective enamel.

It is worth noting that the mammoth had only 4 molars and 2 tusks, which protruded outward and served mainly for self-defense.

After special processing, the molar can be used to make a variety of jewelry products. The density of the material is very high and resembles a stone. In order to process such a product, the master will need to spend a lot of time and effort.

Raw material stabilization

So that the tooth and tusk do not collapse during use and the manufacture of the product from it, stabilization technology is used. This is a critical stage of processing, in which the following technologies are used:

Polycondensation.
vacuum processing.
Application of special dyes.

All voids of the tooth are filled with a polymeric substance, due to which the base acquires reliable protection from climatic influences. Such a product does not deform, cracks do not appear on it, it becomes able to withstand high temperatures. The appearance of the material also changes, becoming more attractive and unique.
