Crucible CPM® Rex® 121® Powder Steel
CPM® REX® 121 (Crucible Industries LLC) is a high-vanadium-cobalt tool steel designed to achieve the high wear resistance, hardness and red-hardness characteristics of high-speed steel. Its excellent red resistance ( red resistance is a characteristic of the heat resistance of steel, indicating the ability of steel to retain high hardness and wear resistance obtained as a result of heat treatment when heated to red-hot temperatures ) provides a higher cutting speed compared to other high-speed cutters. Excellent wear resistance (due to high vanadium content) helps maintain a sharp edge at higher cutting speeds.
Powder high-speed steel was developed in the late 60s of the last century in Sweden. The powder metallurgy method makes it possible to introduce more alloying elements into steel without reducing strength and workability.
Powdered steel, unlike ordinary steel, is fed in molten form through a special nozzle through a stream of liquid nitrogen. The steel quickly hardens into small particles. The result is a powder with a uniform arrangement of carbides (the place where carbides accumulate is the place where cracks nucleate). Carbides perform the same function in steel as cobblestones on the street: they (carbides) are harder than the steel surrounding them and help increase its wear resistance.
The resulting powder is sifted and placed in a steel container, in which a vacuum is created. Next, the contents of the container are sintered at high temperature and pressure, thereby achieving uniformity of the material. This process is called hot isostatic pressing. After this, the steel is pressure treated. The result is a high-speed steel with very small carbide particles evenly distributed in the steel base. The resulting steel can be rolled in the traditional way, just like commercial steel grades, resulting in increased strength.
Differences in the wear resistance of different grades of powder steel are explained by the presence of different carbides in their composition in different proportions and with different uniformity of distribution throughout the entire volume of steel. Of two steels that have approximately the same hardness, the one that contains more carbides or is harder will be more wear-resistant.
CPM REX 121 bridges the gap between high-alloy tool steels and carbide materials ( tungsten carbide, which is second only to diamond in hardness ) . Can be used in cutting tools where high cutting speeds require higher heat resistance but carbide tools are too brittle, or in high wear resistant tools (dies) where carbide tools are also too brittle.
CPM Rex 121 was developed in 1998. In terms of hardness, this is truly a champion, capable of achieving a hardness of 70-72 HRC. For information, officially the Rockwell C scale has a maximum value of 70 HRC.
Also extremely high wear resistance. Difficult to grind and therefore difficult to sharpen. Sharpening this alloy can be a nightmare even at 68HRC, and it will be exponentially harder at higher hardnesses. With so many alloying elements, steel has a lot of carbides, and some of them are not very small. Steel works better with coarse sharpening (the photo below shows a comparison of the microstructures of popular steel grades and the microstructure of CPM Rex 121).
There are many hard steels in the world, but according to renowned knife maker Gary Creely, the REX 121 takes it to the next level. “The steel has a low Rockwell hardness of 40 even after annealing, and after heat treatment it is close to 70 HRC.” The steel is described as Crucible's answer to rival Carpenter CTS steel, Maxamet Micro-Melt Alloy. Although they are very similar in chemical composition, REX 121 contains 1% more carbon and 3% more vanadium. The practical result of this hardness value is unprecedented edge retention. Knives made from REX 121 will significantly outperform even other high-quality steels such as M4 and S35VN.
Steel is not highly impact resistant and can break if abused, but Creely believes that excellent edge retention is more useful than high strength in the small knives we carry every day. “This steel is best suited for smaller knives. If REX 121 finds its way to a larger blade, the chances of it being misused will increase dramatically."
The disadvantage of REX 121 is that it is so hard that it can damage conventional abrasives. “In short, you need to use diamond abrasives to sharpen this type of steel,” notes Creeley. “If you choose your favorite Japanese water stone, there is a good chance that the steel will cut your water stone harder than the stone will sharpen the steel.”
Steel composition:
C 3.4% - the carbon content in the alloy is 3.4%. Carbon is the most important element in steel; it increases its strength and gives the metal good hardness.
Cr 4.0% - chromium content in the alloy is 4.0%. Chrome is a grayish-white, shiny, hard metal. Chromium affects the ability of steel to harden, gives the alloy anti-corrosion properties and increases its wear resistance. Contained in stainless steel of any grade.
Mo 5.0% - the molybdenum content in the alloy is 5.0%. Molybdenum is a silvery-white metal. Molybdenum is a hard-melting element; it prevents the blade from becoming brittle and brittle, giving it the necessary rigidity and making it quite resistant to high temperatures.
V 9.5% - the vanadium content in the alloy is 9.5%. Vanadium is a greyish-white shiny metal with great hardness. It is responsible for elasticity and enhances the properties of chromium, making the metal inert to aggressive chemical environments.
W 10.0% C tungsten content in the alloy is 10.0%. Tungsten is a light gray metal. The most refractory metal, has a melting point tmelt = 3380 °C. Used to create alloys with high strength. Tungsten is used as one of the main components or alloying elements in the production of high-speed steels.
Co 9.0% - the cobalt content in the alloy is 9.0%. Cobalt is a silvery-white, slightly yellowish metal with a pinkish or bluish tint. Increases heat resistance, improves mechanical properties. Processing tools are created from alloys using cobalt: drills, cutters, etc. etc.
S 0.03 - 0.12% - sulfur content in the alloy - 0.03 - 0.12%. Sulfur, like phosphorus, is a harmful technological impurity in steels and alloys. An increase in sulfur content significantly reduces the mechanical and physicochemical properties of steels, in particular, ductility, impact strength, abrasion resistance and corrosion resistance. The limits for sulfur content as a technological impurity are 0.035...0.06%. Due to the extremely fine and uniform microstructure of CPM (Crucible Particle Metallurgy's proprietary powder metallurgy process), sulfur can be added if desired to improve machinability. Higher sulfur content benefits the tool manufacturer by making it easier to manufacture and the tool user by making re-sharpening easier. The CPM process ensures that additional sulfur does not have a detrimental effect on tool strength.
It is worth remembering that when using a knife for its intended purpose and with careful handling, the knife will serve you for a very, very long time.
Ironwood - iron wood - handmade knives
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?
It is quite difficult to recognize the "stone" breed 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 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.
Before the advent of this technology, mammoth teeth and bones were rarely used for making souvenirs, as they did not have sufficient strength due to the large number of cracks and delaminations inside. In addition, tooth enamel has a high hardness, which, when processed, quickly renders the saw unusable. A stabilized product is much easier to post-process. The mammoth tooth has become especially popular in the manufacture of knife handles. It looks unusual, attractive, and if you add dye, you can create a unique pattern that can give even such a rare thing a special personality.
CARBON - KNIFE HANDLES FROM THIS PREMIUM MATERIAL
One of the most prestigious and expensive materials for knife handles, in addition to titanium and expensive woods, is a type of carbon fiber, the so-called "carbon". The material is valued for its exceptional lightness, strength and aesthetic beauty.
Carbon (from the English carbon - carbon) is a polymer material with a composite composition, made from interlaced carbon fiber filaments (carbon fibers). These threads are made using epoxy resins. Average material density from 1450 kg/m³ to 2000 kg/m³. The main difference between carbon fiber and other polymers used in the manufacture of knives is its very low weight. It is the weight combined with exceptional strength that gives carbon an advantage over other handle materials: G10 polymer, Micarta, FRN plastic, etc. At the same time, carbon fiber surpasses structural steels in terms of specific strength characteristics. The main qualities of carbon are: high tensile strength, resistance to high temperatures, aggressive environments, slight expansion when heated, high electrical conductivity. Another important feature of carbon fiber is its natural black color obtained during production, which gives it a noble and elite appearance.
The basis of the material is carbon fiber threads, with an average thickness of 0.005-0.010 mm in diameter. Carbon fibers are made through a complex heat treatment process. The main fiber (polyacryl, viscose) is initially oxidized in air at 250°C for 24 hours. As a result of oxidation, ladder structures are formed (polymers whose macromolecules are crosslinked in pairs by regular chemical bonds). Then carbonization takes place (the process of enriching the filaments with carbon), which takes place when the fiber is heated in nitrogen or argon at temperatures from 800 to 1500 °C. As a result of carbonization, graphite-like structures (allotropic modifications of carbon) are formed. The heat treatment process ends with graphitization (the formation of graphite in materials in which carbon is contained in a dissolved state or in the form of carbides), it takes place at a temperature of 1600-3000 ° C, in an inert environment. As a result of graphitization, the amount of carbon in the fiber is brought to 99%. In addition to conventional organic fibers, special fibers from phenolic resins, lignin, coal and petroleum pitches can be used to produce carbon filaments.
Carbon fabrics, in turn, are obtained by weaving threads or ribbons. In the production of these threads, carbon roving is taken as the basis - a bundle of thin continuous carbon fiber filaments with a thickness of 3 microns, formed by carbon atoms. After interlacing, they form a carbon fiber frame. The amount of carbon fiber in a thread is estimated by the number "K" - the number of thousands of elementary carbon fibers. The thinnest and most expensive carbon fiber is 1K, the most common carbon fiber is 3K, there are also carbon fiber threads with K \u003d 6, 12, 24, 48. Fabric made from threads can have a variety of weaving patterns (herringbone, matting, twill weaving, etc.). To give even greater strength to the fabric, carbon threads are laid in layers, each time changing the angle of the direction of weaving. The layers are held together with epoxy resins. This structure of carbon makes it possible to reinforce the fiber with additional elements that strengthen its structure and give it different colors and surface textures. These materials can be various threads, sequins, polymeric materials of different colors.
The main methods for manufacturing carbon plates are:
Pressing, in which the fabric is lined in a form, previously lubricated with a so-called release agent, designed to reduce the adhesion of surfaces to each other. They can be soap, wax, etc. The fabric is then impregnated with resin and the excess is removed under vacuum (vacuum molding) or under pressure. After polymerization of the resin, the product takes on a finished look.
Vacuum infusion allows you to create a laminated bag by superimposing layers of tissue on top of each other and vacuum is applied under the layers. Then, a binder is fed through the valve and, under the action of vacuum, it fills the voids and impregnates the carbon fabric.
Vacuum forming is the bonding of layers at high temperatures and then exposure to vacuum to form the volume of the product. This method is one of the cheapest.
Winding method, which consists in winding the impregnated roving on a pre-prepared form. After winding the required number of layers, the mold with the wound fabric is placed in a heating oven and polymerized.
The SMC/BMC method consists of placing the fabric in a mold heated to operating temperature. The mold closes, as a result of which, under pressure, the material spreads into the mold cavity and hardens. At the end of the cycle, the product is removed from the molds us, and its final machining and coloring is carried out.
Carbon fiber is used in various fields. In particular, in aircraft and rocket building, in the production of body parts for cars and motorcycles, household appliances and high-tech research instruments. And for about 20 years, carbon fiber has been widely used in the manufacture of knife handles in the middle and premium segments. At the same time, on folding knives, carbon can be both in the form of overlays on steel liners, and in the form of the only material of the handle, fixed with screws through the bonks.
The carbon used for the manufacture of knives, in addition to its main strength characteristics, must also have a fairly attractive appearance. It is this factor that increases its cost, complicating the production technology and requiring the highest quality raw materials. For sizing the layers, the most expensive and high-quality resins are used, and more expensive equipment, in particular chemical reactors (autoclaves). In addition, the carbon fiber is sandblasted to improve hand grip, which also increases production costs. It must also be remembered that working with carbon requires mandatory respiratory protection and special rooms with good ventilation, and this also leads to an increase in price.
The color palette and texture of carbon used on knives can be varied. Among the varieties of carbon are used:
Mosaic carbon, which can be both plain and multi-colored. Such carbon is used for radius spacers on knives with complex multi-section handles. Several dyeing technologies can be used in this carbon.
Marble carbon is a chaotic interlacing of carbon fibers, each of which reflects light differently, which makes it possible to shine from different viewing angles.
Carbon Lightning Strike ("lightning strike") with a copper thread in the form of a grid woven into carbon fabric throughout its volume. Outwardly similar to that used in the fuselages of American aircraft to protect against lightning strikes. This is a thin carbon, 3.2 mm thick twill weave. It has a deep and bright pattern.
Like any expensive, and at the same time difficult to manufacture material, carbon has a number of disadvantages. In the production of carbon fiber plastics, it is necessary to strictly adhere to the technological parameters, in violation of which the strength properties of products are sharply reduced. To control the quality of products, ultrasonic flaw detection, X-ray and optical holography, as well as acoustic testing can be used. Without them, the manufacturer works “by touch” and may not notice hidden defects. Another serious drawback of CFRPs is their low impact resistance. It is also necessary to remember that carbon fades over time and can significantly lose its main advantage - an attractive appearance. However, despite these shortcomings, carbon is rightfully the premium material for the best knives.
