Steel grade DI103-MP (R12M3K5F2-MP) - high-speed powder steel from the Ukrainian enterprise Dneprospetsstal (Zaporozhye). If we give a decoding of the name itself, then D is the manufacturer, I is research, MP is powder metallurgy. The main purpose of Art. DI103-MP: shaped cutters, drills, countersinks, reamers, milling cutters, etc. for processing high-strength, heat-resistant steels and alloys. The hardness of steel DI103-MP is 64-66 HRC or slightly higher. The microstructure is homogeneous. It is considered a very good steel for the manufacture of designer knives and blades. It has good wear resistance and satisfactory impact strength. Holds an edge very well, gives an interesting aggressive cut. Due to the low corrosion resistance, a knife blade made of DI103-MP requires attention and care.
I don’t know where the myth came from that DI103-MP has not been produced since the times of the USSR - this respected steel is made in Ukraine, from where it was successfully sold and is being sold to many countries of the world.

PROPERTIES OF STEEL ELEMENTS:
Carbon (C, Carbon): improves edge retention and toughness; increases hardness and wear resistance; reduces plasticity; in large values reduces corrosion resistance.
Chromium (Cr, Chromium): increases hardness, tensile strength and density; increase resistance to corrosion (>11% makes the alloy stainless).
Manganese (Mn, Manganese) : increases hardenability, wear resistance and toughness; used as a deoxidizer and degasser to remove oxygen during metal melting; in large% increases hardness and brittleness.
Molybdenum (Mo, Molybdenum) : increases hardness, strength, hardenability and density; improves machinability and corrosion resistance.
Nickel (Ni, Nickel): adds toughness; improves corrosion resistance; reduces hardness.
Phosphorus (P, Phosphorus): is considered a harmful impurity. Dissolves in ferrite, due to this, strength increases, but ductility and toughness decrease with an increase in the steel's tendency to brittleness. In low-alloy steels with about 0.1% carbon, phosphorus increases strength and resistance to atmospheric corrosion. It is considered a harmful impurity.
Silicon (Si, Silicon) : increases strength; used as a deoxidizer and degasser to remove oxygen during metal smelting.
Sulfur (S, Sulfur): is generally considered to be a harmful impurity affecting ductility, toughness, weldability, corrosion properties, steel surface quality, etc. The harmful effect of sulfur reduces the presence of manganese in steel. The sulfur content in quality steels does not exceed 0.02-0.03%.
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.
Tungsten (W, Tungsten): adds strength, toughness and improves hardenability; retains hardness at high temperatures.
Cobalt (Co, Cobalt): increases strength and hardness, allows hardening at higher temperatures; enhances the effects of other elements in complex steels.
Niobium (Nb, Niobium) : limits the growth of carbides; limits workability; creates the hardest carbides.
Nitrogen (N, Nitrogen) : used instead of carbon in the steel matrix (nitrogen atoms function similarly to carbon atoms, but have advantages in corrosion resistance)...
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".
Poplar (Osokor)
Black poplar or Osokor (Populus nigra) is a tree from the Willow family, widespread in Eurasia. It is characterized by rapid growth and a high trunk - in 20 years it can reach a height of 30-35 m and 1-2 m in diameter. Relative unpretentiousness, adaptability to wide distribution and growth rate make poplar wood an affordable and widely used material. In addition, poplar plays a big role in urban greening and air purification, and its buds and bark are used to create medicines.
Poplar wood has a brownish heartwood with a smooth transition to a lighter beige sapwood. The texture is uniform and straight, with the exception of burls and burls - these parts of the tree are more decorative, valued much more and are more often used to create handicrafts.
The availability of poplar wood allows it to be used in construction, carpentry and carpentry, but earlier this material was considered insufficiently stable and sustainable. With the development of wood processing products, the blackberry has become more popular, since now its main shortcomings can be stopped. So, protective oils eliminate vulnerability to moisture and microorganisms, and high-quality stabilization makes poplar wood dense and heavy.
Due to its softness and ease of processing, poplar is often used for woodcarving with hand tools. They make wooden utensils and spoons, toys, souvenirs, figurines from it. The stabilized burl, suvel and basal parts of the osocor are used for the manufacture of knife handles, box mods for electronic evaporators, costume jewelry and jewelry. The low density of poplar wood allows it to be stabilized at home, and the addition of fat-soluble dyes in the process enriches the texture of the wood, which in its raw form is not expressive.
Poplar bark is used for vegetable tanning of genuine leather due to the content of tannins in it.
Density: Poplar has a below average density - 385-500 kg/m 3 . It is a light and soft wood species.
Processing: Blackberry wood is easily cut by both machine tools and hand tools, provided that the cutting edge is sharply sharpened. Due to the soft and friable structure, it is difficult to grind, it lends itself better to fine grinding with fine abrasive grains. Poplar accepts finishing compositions and stains well, it also sticks together easily.
Osokor can be bent, therefore it is suitable for the manufacture of bent products. With fluctuations in air humidity, untreated wood has a high tendency to warp.
For the manufacture of products that require strength, moisture resistance and wear resistance, poplar is recommended to be pre-stabilized.
Examples of poplar wood products:
Black poplar is a species often used for woodcarving with hand tools:
Poplar heartwood has a calm texture and, as a rule, a uniform color:
Since ancient times, poplar has been used to make dishes and cutlery, since antibacterial properties are attributed to its wood:
After stabilization, poplar becomes a suitable material for creating handles for household knives:
Most of all, knifemakers appreciate poplar burls, which have an unusual texture:
Coloring poplar burls and suvels during stabilization gives rise to bright and spectacular color combinations:
Since poplar becomes strong and resistant to moisture after stabilization, it can be used for knife handles that face harsh conditions:
Also, stabilized speck is used to create souvenirs, collectibles and gift items, for example, exclusive writing pens:
