Knife - Essential Tool for Camping, Outdoor Adventure and collection

Japanese steel blends with Italian excellence

For this 2020 collaboration, exclusive of Collini Cutlery, we have decided to propose a series of best sellers produced by Extrema Ratio. Knives made with the famous San Mai steel produced by the Japanese Takefu Steel. Specifically, we used V-Toku2 carbonaceous at 62 / 63HRC for the central plate and SUS410 stainless steel for the two external plates, in order to guarantee a very high cutting capacity, penetration and sealing of the wire together with an ease of re-sharpening. and maintenance but at the same time the blade has a remarkable resistance to corrosion and an important increase in resilience given by the type of external steel and by the laminated structure.

Col Moschin Compact model: for this First Production Run a run of 10 pieces numbered from 1 to 10 was created.

As in the ancient Japanese Samurai swords.

Rolled steel - imported into Italy by Collini Steel directly from Japanese Takefu Steel - is based on the ancient Japanese tradition in the creation of the famous Samurai swords. In fact, as early as 1100 the expert Japanese blacksmiths combined different materials together to give the Katana swords incredible cutting capabilities combined with a resistance and flexibility previously unknown. It is thanks to this revolutionary construction technique that Samurai swords have been preserved to this day, becoming one of the most fascinating objects made by man. Following this tradition applied to modern metallurgy, today we are able to have technologically advanced steels already tested and used in cutlery also by famous brands such as Fallkniven, Cold Steel, Mcusta, Kai, Sog, Zwilling, Rockstead, etc.

Characteristics of San Mai steel: These are different types of metals bonded together to create a composite that encloses and intensifies the strengths of the metals individually taken:

- Longer tool life
thanks to the use of very high quality steels with high carbon content (VG10, CoS, Shiro) or sintered (SPG2), in the heart of the sheet (Core Steel), the blade, once hardened, achieves decidedly hardness and cutting performance higher than those achieved with the use of traditional steels.

- Greater resilience
built with the principle of Japanese swords, multilayer steel is difficult to break thanks to the toughness of the central steel (Core Steel) and the elasticity of the steel used for the side coating (Stainless Steel).

- Better corrosion resistance
the steel used for the external layers (Stainless Steel) guarantees the blade a high resistance to corrosion. The combination of the two or more materials used by Takefu Steel generates, on a galvanic level, a structure that improves corrosion resistance even on the wire.

- Easy processing even after heat treatment
although steel normally becomes harder after quenching, the lateral steel used in multilayer processing does not lose its softness and allows easy processing, drilling or welding even after heat treatment. For an optimal performance of the blade, cryogenic treatment is recommended.

- Improvement of the aesthetic result
The knives made with multi-state steel or damascus pattern at the end of the processing are aesthetically elegant, refined and highly appreciated by collectors all over the world.

The Extreme Ratio E.C.M. (Einsatzkommando Cobra Messer) is a fixed blade multipurpose knife, designed for operational uses for the famous Einsatzkommando "Cobra" special unit of the Austrian police, whose logo is laser engraved on the heel of the blade.

On December 19, 1941, in Eluet El Asel, about 400 men from the 1st Royal Carabinieri Battalion Paratrooper faced the assault of 4 battalions of Indian troops of the British Army. Jumping from their trenches by launching improvised devices, the "Desert Lions", as Radio London called them, made the defensive line impenetrable by allowing thousands of Italian-German troops to withdraw safely. This was the first page in the long history of Italian paratroopers.

The Tuscania Paratrooper Regiment asked that the Extra Ratio T911 be specifically made as a commemorative knife for its 80th anniversary.

The T911 is a medium-sized folding light and designed for professional use by military operators. It is equipped with a modified spear point blade, flat edge, in Bohler N690 cobalt steel heat-treated to a hardness of 58 HRC, for the best compromise between strength, ease of regrinding and thread hold. The blade is 76 mm long, 4 mm thick, has a stone washed finish and rotates around an adjustable pin which allows to obtain the best fluidity in opening. A brace allows you to lock the pin in the best position.

The handle is in Anticorodal aluminum alloy with high strength black anodized finish and is milled to facilitate the transition from "reverse grip" handle to saber handle.

The blade is opened by means of a pin operated with the thumb. The knife uses a liner lock type blade lock and a safe ensures maximum hold even during heavy use. The safety lever is colored red for better visibility and engages in an advanced position for more instinctive use.

In the handle are integrated a seat belt cutter with easily available and replaceable cutter-type blade, a tungsten glass breaker, a stainless steel knot loosener and a screwdriver for adjusting the pointing optics, in AISI 420 steel. The clip , reversible and fixed at the end of the handle, allows a very deep port in the pocket, for less visibility.

The knife can be dismantled for cleaning and maintenance. With a total length of 194 mm and a weight of 145g, the T911 is easy to wear both in uniform and in civilian clothes.

RESOLZA, a term of ancient origin, is today one of the most famous traditional knives of our country. The name suggests the razor by chance.

It was born in Sardinia centuries ago and has accompanied its inhabitants until today in the daily work of a peasant and pastoral life, following them even when its men were called to war. The chronicles of the Sassari Brigade during the First World War cite this knife among its soldiers' equipment.

We wanted to make a tribute by revisiting it according to our canons, without wanting to hurt any of the prestigious Sardinian artisans who still today pass on the tradition and wisdom of their ancestors. The dimensions and proportions are the original ones of a 10 cm blade, but the materials and technologies are those of our production. The handle revised in our style, the blade most faithful to tradition. In addition to the original, it has the blade lock open.

Extrema Ratio developed the first knife of a new production line, called CONTACT.

It has a blade with a lance-shaped profile, a flat grinding and a diamond-shaped geometry. It has got a lower guard branch to protect itself from incidental cuts, upper jumping to improve grip, concave fuller along the length of the blade and a generous thickness blade (6.30mm) the now famous Requiem, revisited in proportions and in some technical features. The first of a new line of multipurpose knives.

The blade is made in Böhler N690 steel with a hardness of 58 HRC and a chemical burnishing coating for the Black version. All other colors in production have got a blade with Stone Washed finishing. The handle is still in forprene. It is more assembled by the side screws but thanks to the shank in truncated cone-shaped stainless steel that is screwed to the bottom and goes to fit inside a special seat, which makes it solid. In this way the knife is well balanced. The sheath is minimalist; most of the fabric has been cut off; it has got a 2nd level retention system, remembering the style of the model it was inspired by.

The main shell is injection-molded in shockproof nylon. The secondary retention system is reversible for ambidextrous users. The blade is guided through the conception of the blade. To extract the blade, to pressure the trigger will be sufficient, thus releasing the safety that holds securely in the sheath. In the horizontal slits of the sheath of a system, which fixes the blade to avoid shaking noises when it is stored inside. The back side of the nylon sheath is M.O.L.L.E. compatible.

The textile part is reduced to its minimum and has got the classic two-button safety strap with a belt loop Extrema Ratio aims to reduce the size of the knife, but not saving on the structural strength and safety accessories.

Born from the revisitation of the 39-09 model, the Nimbus was developed and chosen by the 183rd "Nembo" Paratrooper Regiment as a commemorative knife of the events of Case Grizzano which on 19 April 1945 saw the Nembo paratroopers engaged against the paratroopers of a German division . The clashes raged for 12 hours and were often resolved by hand-to-hand combat with the white weapon. A few days after the end of the Second World War one third of the battalion's men remained on the field, but their sacrifice led to the conquest of the battle. The knife in addition to wanting to commemorate an important event of our Armed Forces is the result of a development that has been carefully studied also in the technical aspects, so as to make it suitable for a concrete operational use.

Particular attention has been paid to taking care of the dimensions, the shape and the search for solutions such as the kydex sheath, which is designed to make the knife an instrument capable of adapting to the most complex requirements of the port.

The light and compact blade meets the demands of a modern tactical knife today.

Dedicated to those who are more at ease with a knife with a more classic profile, the VENOM is characterized by a wide, flat main grind.

Less suitable for combat, it is best expressed in field and precision work (thanks to the lower angle of sharpening).

It is a multirole of great utility in hunting and outdoor sports. The profile and the general outline of the blade are inspired by the Italian and Austro / Hungarian battle blades of the first half of the 20th century.

The particular situation created in the early years of the 1914/18 war, now mired in increasingly complex and protected trenches and fortifications, favored the formation of men who, little by little, specialized in the coup.

Our assault units, the Arditi, had their dagger. It was obtained from the pieces cut away by the long blades of the Vetterli 1870 bayonets, which in the narrow trenches, in the corridors, between the reticulars were only an obstacle. It was certainly a rustic weapon, of recovery, not too beautiful but certainly inexpensive, light, not cumbersome and in expert hands also effective.

Today, on the occasion of the centenary, we recall this important page of Italian military history with a limited celebratory series in only 100 numbered copies. This version has a satin blade and a walnut wood handle and is sold with a wooden box and leather sheath.

The new Zero Tolerance 0609 is a smaller, even more carry-ready version of the original Factory Custom 0606CF from ZT, RJ Martin, and Matt Martin. Like the original, it offers a clean, streamlined look yet also has highly detailed handle machining that adds both grip and visual impact. For even more visual “wow,” the 3D-machined handle is built of light-yet-strong titanium that ZT has anodized in an attractive bronze.

The 3.4-inch blade is CPM 20CV, which provides enhanced toughness and resistance to edge chipping. It also delivers superior hardness, corrosion resistance, and excellent edge retention. The drop-point blade has a two-tone finish: machined satin on the grinds with a stonewashed finish on the flats. The new 0609 opens manually with ZT’s KVT ball-bearing opening system and the handy flipper so it’s always ready when you want it.

Last—but certainly not least—you’ll notice the oversized See-Through Pivot (STP). Designed by RJ Martin, this unique, pivot is hollow in the center, letting you “see through” it. The See-Through Pivot adds another intriguing touch to this already-attractive knife.

ABOUT THE STEEL

More than just a damask, Coreless steel made by Japanese Takefu Steel comes with over 70 layers of VG10 and VG2 stainless steel welded, forged and coated between them so that you can form a lightweight, slim and durable blade with a spectacular damask outer pattern.

The peculiarity of Coreless steel, unlike conventional rolled steel or Japanese San-Mai, is that it does not have a hard core steel that is used for the cutting edge but has both the VG10 and VG2 steels arranged to form the cutting edge so alternating and sequential to each other.

This particular construction gives the blade - compared to the two steels that make it, individually taken - greater resistance to oxidation, higher surface hardness (up to 61.5HRC), 25% more than cutting capacity, 25% more than the wire hold capacity and 25% more resilience making the blade more robust and less subject to breakage.

Thanks to this latest steel, Takefu Steel has been rewarded on Japanese territory for research and development and innovation in the cutting-edge landscape. Coreless steel has already been chosen by major brands such as Kai and Mcusta Zanmai who since 2017 proposed it on their top productions of professional kitchen knives.

Notes: Design by Rick Hinderer - Opening of ball bearings Ball Bearing System KVT - opening via Carson Flipper system

The Zero Tolerance 0808BLU, with blue-anodized handle, is a sprint run built in a limited quantity.

The 0808 is a collaboration between ZT and custom knifemaker Todd Rexford and is based on his Cesium model. It features advanced-formula stainless steel and ZT’s smooth-as-silk KVT opening system. The 0808’s blade is built of Crucible S35VN stainless steel. This powdered metallurgy steel is extremely fine-grained so it can be sharpened to a razor edge. Added niobium and nitrogen enhance toughness to resist chipping and provide excellent edge retention. Yet it’s also easy to re-sharpen.

Opening is fast and simple with KVT. Caged ball bearings surround the pivot to make the blade quick and easy to open using the built-in flipper. With KVT, the 0808 is as easy to open as any assisted knife, but without the need for a spring.

The 0808GLD’s blade is paired with chamfered titanium handles that provide a solid, comfortable grip. The sturdy frame lock has a hardened steel lockbar insert to offer extra-secure, extra-solid blade lock up. The reversible pocketclip enables you to carry comfortably left- or right-handed.

This blue-anodized edition of the 0808, the 0808BLU, is a sprint run. Quantities are limited. Check with your local ZT dealer for availability.
