Crucible CPM® 20CV™ Powder Steel

Steel CPM® 20CV™ (aka Duratech CV20) is a high-chromium, high-vanadium, corrosion-resistant powder steel produced by Crucible Industries (USA). Recently, the alloy (and analogues, for example M390 ) are gaining popularity on serial and designer knives. And deservedly so - this steel combines high cutting edge durability (with a hardness of HRc 62-63, it is approximately one and a half times better than CPM S30V at 61-62) with good corrosion resistance and decent mechanics.

CPM20CV guarantees high impact strength and is able to withstand "heavy" work in extreme conditions. In addition, the steel has an aggressive cut. Among the disadvantages - it is somewhat more difficult to process; for a good result during heat treatment, cryotreatment is required.

The steel is made using amorphous metal alloy technology, better known among knife manufacturers and hobbyists under the abbreviation CPM (Crucible Particle Metallurgy). The CPM process produces very uniform, high-quality steel that has superior stability, uniformity and toughness compared to traditional heat-produced steels.

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.

Steel composition:

C 1.9% - the carbon content in the alloy is 1.9%. Carbon is the most important element in steel; it increases its strength and gives the metal good hardness.

Cr 20% - the chromium content in the alloy is 20%. 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 1.0% - the molybdenum content in the alloy is 1.0%. 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 4.0% - the vanadium content in the alloy is 4.0%. 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 0.6% - tungsten content in the alloy is 0.6%. 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.

​Gentle from kydex

Author: GrandWay author

Kydex is a material popular in the manufacture of sheaths, sheaths for knives and other elements of improvised equipment. Kydex belongs to the group of thermoplastic acrylic-polyvinyl chloride materials. It is produced in the form of sheets of various thicknesses, from which, with the help of heating, the products we need are formed. Typical products for which kydex is used: scabbards, covers, clamp fasteners, holsters, pouches for rifle cartridges and magazines for automatic weapons.

Holster knife sheaths and sheaths

In addition to sheaths for knives made of kydex, you can also purchase accessories made of holster. Canvas (Holstex) is the last word in thermoforming materials. It is very similar to kydex, but much stronger than its "brother", and was originally developed specifically for the formation of small products.

Gentle from kydex and holtex - the main advantages:

• water resistance: they are not afraid of moisture or water;
• wear resistance, load resistance, low abrasion;
• optimal combination of rigidity and elasticity - the knife is protected and clearly fixed.

There is an opinion that kydex or Holtex is best suited for work knives intended for intensive use, which will not regret, and for which the perfect appearance is not particularly important.

For example, sand will get into a kydex or Holtex case - it will stick to the blade or something. And, acting as an abrasive, scratches your blade in every way. But, first of all, this is also possible with sheaths made of other materials. And secondly, kydex allows you to make not only sheaths for knives with a fixed blade, but also for complex models, not to mention a lot of other equipment.

Kydex or Holtex folding knife sheaths are more than just sheaths, they are convenient attachments that allow you to place your folding knife on your clothing or gear for maximum comfort and accessibility.

And, of course, no negative points can defeat all the advantages of kydex. This is both general reliability, and the above-mentioned water resistance, and the variability of suspension and fixing. For example, if you prefer to carry a knife in a hilt position, then a kydex sheath is the best option for this. Knife, scabbard, kydex - a triad that is characteristic of many modern models used by tourists, hunters, military, bushcraft enthusiasts and residents of harsh regions.

Kydex scabbard attachment

By themselves, kydex-gentle ones are practically ready-to-use accessories for knives. Such sheaths are accessories, kydex: basic equipment.

You can improve, supplement the functionality, provide new opportunities with the help of additional devices. This possibility is the main advantage of kydex sheaths.

The easiest way to upgrade a scabbard or cover is with a kydex clip. Some clips and clamps are molded from the same kydex when manufactured. For some, special seats are made with the help of grommets, special platforms. It all depends on what type of kydex sheath clip you like best.

The other most common type of fastener is a kydex scabbard snap lock: tek loc. There are also their varieties or simply more complicated - roto-lock, molle-lock, etc. In the Grand Way online store, you can buy tek lok separately or get it in a set as an addition that improves the functionality of your vagina.

Making sheaths from kydex

There are several thicknesses of kydex. The most common are 0.06" (1.5 millimeters), 0.08" (2 millimeters), 0.093" (2.4 millimeters), 0.125" (3.2 millimeters).

The most universal optimal thickness of kydex is 2 millimeters. And here's why. With a thickness of 2.4 millimeters, problems already begin - the material is not formed so well, the contour lines of the kydex knife are unclear, and the extra thickness is more of an obstacle in this case.

For small knives, with blades up to ten centimeters, a thickness of 1.5 millimeters is sufficient. At the same time, it provides the cover and the necessary elasticity.

However, another nuance is more important than the thickness of the kydex. This is the presence of pronounced fixation points of the knife. For example, if it has a well-defined underfinger notch or stop, then thin kydex is also suitable. And if the design of the knife does not provide for such points, then even if you use Kydex of 2.4 millimeters, normal fixation will not work.

That is, kydex as a sheath material is suitable for any model of knife, but not with every knife the functionality of kydex is fully revealed. It turns out that simply making a sheath from kydex is only half the battle. At the same time, it is important not to forget about the combination of this material and the finished product from it, with a knife, and to think over the design of the scabbard in advance so as not to make mistakes.

Therefore, on the website of the Grand Way company, you can buy both basic, ready-made models of covers for specific knives, and order a product individually, taking into account all the details that are important to you and for any of the selected knives. Are you choosing a knife, and what material will the scabbard be made of: buy kydex, a product made of it will be the most optimal option.

Also, it should be noted that the custom-made kydex sheath service applies not only to knives - simple or folding. It is possible to make sheaths from Kydex or Holtex not only for them, but also for multitools, Swiss knives, flashlights and other elements of hiking, army equipment or EDC kit.

You can choose the color of future sheaths, their device, the texture of kydex, and even order sheaths made of holtex - a more "advanced sibling" of kydex.

Not only retail purchases of Kydex or Holtex covers are also possible, but also wholesale orders. All questions and details can be clarified before ordering, directly from sheath manufacturers or consultants of the Grand Way online store. In general, it is very convenient that you can buy and order a knife + kydex - as a practical and very suitable sheath material for it. If you like custom made, kydex as a material, this is the place to order your modern multifunctional sheath.

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".
