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.

WHAT ARE MICARTA AND G10 AND HOW THESE COMPOSITE MATERIALS DIFFER FROM EACH OTHER
For decades, Micarta and G10 composite materials have been undisputed leaders in the knife industry, in particular for the production of handles of various complexity. The materials are distinguished by their availability, ease of production and processing, as well as high strength, wear resistance and unpretentiousness in maintenance. Both materials are composite, based on polymer resin, which is supplemented with layers of different types of captive fabric.
Micarta-G10-Composite-materials-photo-2
Micarta material is an electrical insulating material consisting of a polymer film (based on cresolaldehyde, phenolaldehyde, xylenolaldehyde resin, or resin from a mixture of phenolic raw materials). It is glued with the help of various electrically insulating papers, fabric (mainly linen of natural or artificial origin), or other materials of a similar structure, there are also options made of fiberglass and carbon fiber. The color of the material depends on the resin and fabric base used for gluing. Micarta is a relatively soft material and requires careful manual processing. Therefore, it is used in the production of handles for more expensive knives.
Micart is registered as a trademark of the American company Industrial Laminates / Norplex, Inc. (Norplex-Micarta). Its domestic analogue can be considered a material called "Getinax", which is mainly used as a basis for printed circuit boards. The material also has a sheet pressed structure, which consists of a paper base with the addition of phenolaldehyde or epoxy resin impregnation.
Linen-based micarta has a more attractive optical effect when sanding the fibers. After grinding, the surface can be polished or sandblasted. In the first option, the surface of the material will be smooth, silky, warm and pleasant to the touch. And in the second, the material becomes rough and has a matte shade, besides, it is securely held in the hand and does not slip.
Main characteristics of Micarta:
increased water resistance;
excellent resistance to temperature changes;
strength to mechanical processing;
dense structure that does not absorb odors;
the micro-relief of the material does not slip in the hand even when the surface is wet;
tight fit to the blade, which leaves no gaps at all and prevents food residues and harmful microorganisms from accumulating.
G10 material is a light, hard and fairly stiff composite material with a textured surface, which is mainly used in the manufacture of handles of both folding pocket knives and knives with a fixed blade. This material is created by placing several layers of fiberglass, thoroughly impregnated with epoxy resin, in a special vacuum press, where, under the influence of compression and heat, the resin finally hardens, preserving the structure of the fiberglass.
The G10 material is characterized by good impact resistance, wear resistance, moisture resistance, as well as ease of processing and maintenance. The material can be painted in different colors, including in layers. The surface of G10 can also be polished to a glossy state, or have a rough anti-slip structure, under the influence of a grinding machine or sandblasting.
Key features of the G10:
high stability of basic properties during temperature fluctuations;
withstands high shock loads, compressive and tensile loads;
high overall hydrophobicity and resistance to chemicals;
weighs relatively little, in relation to the overall strength and density;
low electrical conductivity;
can take different forms.
Composite materials G10 and Micarta have almost the same composition and external similarity. At the same time, the G10 material has higher fire resistance, although it is not a non-flammable material, it has higher compressive, bending, impact and tear strength, and it is also simpler and more economical to manufacture. At the same time, G10 is inferior in terms of "stickiness" in wet conditions, and also, tactilely, it feels less "natural".
Wood species for knife handles
Stabilized hornbeam imitates the texture of ebony wood.
Ebony is one of the most valuable species of wood growing in Africa. The high price is due to the rarity of the breed, the fact that the wood has a large amount of sapwood (the layer of wood between the bark and the core), which allows you to use only about 30% of the trunk for products. In addition, ebony is prone to cracking, which is unacceptable for a knife handle. Black hornbeam, thanks to impregnation with resins, repeats the texture of ebony and is not prone to cracking, in addition, hornbeam handles are extremely strong due to the high density of wood, which makes it an ideal material for making knife handles in black color.
In the photo (left-right): ironwood, resin-stabilized hornbeam bar, stabilized hornbeam handles.
Wenge is a tropical type of wood that is often used to make knife handles, not only because of its beautiful structure, but also because of its physical properties. It is characterized by an extremely coarse texture with straight veins. It has extremely high impact resistance, which will allow the handle to last as long as the knife blade. Resistant to decay. The color scheme can vary greatly from golden brown to dark brown with black veins, for the manufacture of knife handles blanks from the core of the trunk are used.
Bubinga or otherwise African rosewood has a beautiful and extremely rich structure with beautiful veins of pink and red. The sapwood of a tree is suitable for the handles, in this case, the only difference will be the color, the sapwood is a few shades lighter. Extremely dense (from 800 to 960 kg/m3) and heavy type of wood, but Bubing handles look thorough and solid. Not prone to cracking, good resistance to moisture and fungus.
Paduk is an extremely common tree in the southern hemisphere. One of the most water-resistant types of wood (when in contact with the soil, it can last an average of 25 years), it is well suited for knives for fishing, hunting in rainy and humid weather, because it does not slip in the hand, even when wet.
In the photo (left-right) handles made of: bubingu, wenge, paduka.
One of the oldest materials for making knife handles is bone and animal horns . Like wood, the material is natural, moose horn is most often used for knife handles. A very difficult material for processing compared to wood, but sheepskin is worth the effort, the handles are exclusive and not similar to each other, if a huge number of handles can be made from a tree trunk, then a very limited number can be made from the horn of one moose.
When ordering a knife with a handle made of elk horn, you should understand that it may differ slightly from the one you see in the photo, here, just like with human fingerprints, no two are exactly the same.
The only disadvantage of this material can probably be considered only the inconvenience of using it for hunting in winter, in the cold the horn handle gets very cold and it will be very uncomfortable to hold it with a bare hand.
Birch is practical and convenient as a material for the handle, its main advantage will be that the handle does not slip in the hand, even if a large amount of water has fallen on it. Well, of course, birch is native to us, not wood from Africa and the tropics. Birch typically contains a large amount of tar, which gives it disinfectant properties and protects it from rotting, no parasites and fungi will take root on birch. Extremely good material, for fishing knives, a small knife with a birch handle, can stay afloat after entering the water.
Sapale is another type of wood originally from Africa. Extremely beautiful palette structure from light pink to reddish-brown color. It is not prone to cracking and has a high hardness, from 4.1 to 4.5 Brinell units. All types of wood presented on the site are great for making knife handles and mostly the choice of a knife with a specific handle has an aesthetic value, depending on your personal preferences.
In the photo (left-right) handles made of: elk horn, birch, sappel.
Handles can also be made of several types of wood, with "senvdych" inserts next to the guard of the knife, or in the middle of the handle. All types of wood presented on the site are great for making knife handles and mostly the choice of a knife with a specific handle has an aesthetic value, depending on your personal preferences.
High-quality and original steel inserts are a wonderful decoration of exclusive and unique knives of the Studio of exclusive handmade knives Fomenko Knifes (Ukraine), which offers to order and buy online store https://knife.net.ua
