Magnum continues the tradition of its annual knives and presents the Collection 2023, a collector's knife with exceptional appeal. Passionate knife collectors around the world will once again be faced with the choice of whether the knife should find a place in the display case or on the belt. Lucas Burnley, considered one of the world's most renowned knife designers and who has already launched several successful knife series for Boker and Boker Plus, was won over for this special project. The knife maker from the U.S. state of Oregon knows how to combine clear lines and tactical influences in his designs like no other.

The Magnum Collection 2023 is an impressive full tang outdoor knife with a massive D2 blade that features a pronounced ricasso and an unusual two-tone finish. The designer alternates between a horizontal and vertical finish on the blade, which underscores the special appeal of the fixed-blade knife. Attention to detail also continues in the contoured handle with black polished Micarta grips that gives excellent user ergonomics for effortless work. Features include a high-quality leather sheath with two snap fasteners, an exclusive collector's box, and a certificate of authenticity. The Magnum Collection 2023 is strictly limited to 1999 pieces worldwide.

For this year's Damast Annual Knife we collaborate for the first time with Ricardo Romano Bernandes. Romano, whose family originates from Sicily, was born in Brazil, has been a knife maker since 1990 and his craft is part of a tradition of knife making and sharpening established over several generations. His design is based on traditional Pen Knives and immediately inspired us with its casual freshness.

For the modern interpretation of a traditional knife shape, the powder metallurgical damask of the Swedish company Damasteel seemed to us the appropriate material for the blade. Damasteel's production requires - even if the most modern technical means are used - just as much skill and experience as the hand-forging of steel. The purity and properties of Damasteel steel can be optimised to the extreme with complex combination processes.

The self-supporting structure in blue and grey rolled G10 contrasts beautifully with Damasteel's 'Odin Eye' motif. The simple but always functional slip joint is an obligatory part of this knife. The size, weight, indestructible G10 sheaths and stainless Damasteel make this collector's knife an excellent EDC. Limited to 999 examples worldwide.

Special limited edition model created on the occasion of the XXV Anniversary of Extrema Ratio

Extrema Ratio Misericordia Black Warfare is a version in a limited series of only 500 pieces that preserves intact all the features of the famous Misericordia model adopted by the 4th Alpine Parachute Regiment, which helped develop and test the product and chose it for its unique characteristics that make it particularly suitable for ambush combat.

The blade is milled from Böhler N690 steel, hardened to 58 HRC for the best balance of edge retention and strength, is 118mm long, 4mm thick, and has a flat edge. The weight of the knife is just 87g. It has a spear-point profile, with a full-length shank that makes it even lighter, features ¾-length false counter-wire, and has a Black Warfare finish, with the innovative and original Extrema Ratio Geotech Camo pattern, made by laser engraving.

The handle retains the unmistakable Extrema Ratio ergonomic profile, and is made of fiberglass-filled nylon to ensure absolute robustness in all conditions, even in the heaviest of uses. The distinctive ring on the bottom of the grip aids hand grip by allowing the soldier a greater and firmer lunge, exponentially increasing the combat potential of the Misericordia.

The Kydex scabbard offers belt-clip, ulti-clip and malice-clip attachment options. In addition, it is possible to attach the scabbard to the M.O.L.L.E. system by braiding the paracord lanyard. The Misericordia Black Warfare comes in an IP67-certified watertight Polypropylene technical case, with pressurization valve, weatherproof, dustproof and shockproof, inside of which is also the Kydex sheath, double UTLICLIP, double-grit sharpening plate (ceramic abrasive and synthetic diamond) and metal plaque with the progressive number of the limited series.

The great interest in Tirpitz-Damast damask over the years has convinced Boker to design another model supplied with the historic damask steel. The Boker Barlow Prime Tirpitz Damascus, much more compact than the original model, convinces not only in the collector's showcase, but also as a gentleman's knife. The blade made in the exclusive Tirpitz Damascus, is supplied with a modern elongated ricasso and opens with a nail notch. Damascus made with the material acquired from Tirpitz, sister ship of the legendary Bismarck which was the largest warship ever launched for the German Navy.

Soon after the end of World War II, a Norwegian specialist company began cannibalizing the ship, which sank off the Norwegian coast, in order to make the high-alloy steel available for civilian purposes. Norwegian divers recovered parts of Tirpitz's special armor from the fjord for Boker. From these pieces of living history, Damascus blacksmith Boker exclusively forges an extraordinary damask with a fascinating history. The combination of Tirpitz steel with carbon tool steels also results in an extremely strong Damascus which, with a Rockwell hardness of 61 to 63 HRC, is up to any task in everyday use.

The operational safety of the history-rich slipjoint pocket knife is further enhanced by a 90 degree locking mechanism when opening and closing. The characteristic teardrop shape of the Barlow is attributable to the English pocket knives of the seventeenth century, which certainly makes it one of the oldest models ever. The name of the classic probably dates back to an enterprising knife manufacturer from Sheffield of the same name, who began exporting the sturdy knives to North America around 1800. There they immediately enjoyed great popularity and so the first Barlow models also appeared in the history of the Boker Manufactory. Solingen at the end of the 19th century.

This integral version of the timeless classic with a contoured black micarta handle body, which is milled from solid and also forms the signature Barlow bolsters. neither. Handmade in the Boker knife factory in Solingen.

Japanese steel merges with Italian excellence

For this 2021 collaboration, exclusive to Coltelleria Collini, 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 have used the carbonaceous V-Toku2 at 62/63HRC for the central plate and the stainless SUS410 for the two external plates, in order to guarantee a very high cutting capacity, penetration and edge holding together with an easy resharpening and maintenance but at the same time the blade has a remarkable resistance to corrosion and an important increase of resilience given by the type of extreme steel and the laminated structure.

Intended Use: Neck Knife / Collector's Knife

Type of production: Industrial
Country of Production: Italy
Blade / Handle: Full, laminated Japanese steel (San Mai) with V-Toku2 (carbonaceous) cutting edge at 62/63HRC and SUS410 (stainless steel) outer cheeks
Blade finish: Satin finish
Blade length: 40mm.
Blade thickness: 3mm.
Total length: 129mm.
Weight: 55g.
Sheath: Kydex, for neck.
Packaging: Cardboard box with Extrema Ratio logos.
Notes: Numbered edition - cardboard box with Extremaratio logos and certificate - the central core of the blade and handle is made of carbon steel so it is recommended to wash/dry the knife very well after each use and protect the steel, during storage, with a light surface of lubricant to avoid rust and oxidation.

As in the ancient swords of the Japanese Samurai.

The rolled steel - imported in Italy by Collini Steel directly from the Japanese Takefu Steel - is based on the ancient Japanese tradition in the creation of the famous Samurai swords. As early as 1100, expert Japanese blacksmiths combined different materials to give Katana swords incredible cutting capabilities combined with previously unknown strength and flexibility. It is thanks to this revolutionary construction technique that the Samurai swords have been preserved until our days becoming one of the most fascinating objects made by man. Following this tradition applied to modern metallurgy, we are now 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: It is made of different types of metals alloyed together to create a composite that contains and intensifies the strengths of the metals individually taken:

- Longer cutting edge life
thanks to the use of high quality steels with a high carbon content (VG10, CoS, Shiro) or sintered (SPG2), in the core steel, the blade, once hardened, reaches hardness and cutting performance decidedly superior to those achieved with the use of traditional steels.

- Greater resilience
Built on the principle of Japanese swords, the 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 lateral coating (Stainless Steel).

- Improved corrosion resistance
The steel used for the outer layers (Stainless Steel) gives the blade a high resistance to corrosion. The combination of the two or more materials used by Takefu Steel generates, at a galvanic level, a structure that improves corrosion resistance even on the edge.

- Easy machining even after heat treatment
Although steel normally becomes harder after hardening, the lateral steel used in multilayer machining does not lose its softness and allows easy machining, drilling or welding even after heat treatment. For optimum blade performance, cryogenic treatment is recommended.

- Improved aesthetic performance
Knives made of multi-state steel or damask pattern at the end of the processing are aesthetically elegant, refined and highly appreciated by collectors all over the world.

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.

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.

Extrema Ratio is proud to present the Culter Venatorius that, so as not to contradict the current address is a technical knife, practical, perhaps a bit 'specialized and that gives a nod to tradition and to the tastes of the most traditionalist hunters who like to do everything yourself.

The Latin motto engraved on the blade reads:

"I am the hunting knife, I am the claw beak and fang of my master. My job is as old as the flesh and blood.", We find that describes significantly the pure essence of the instrument.

We feel to say that if a tool could be capable of humor probably would have added: "It 'a dirty job ... but someone has to do it ...".

The Culter Venatorius, more than a knife, is a complete equipment for slaughtering and skinning of medium and medium-large sized prey, suitable for ungulate hunters.

The kit includes: a knife to slaughter and general use, one skinner provided with cross handle to skin and clean the internal organs the animal, a carver to skin head and snout and a stone with two grains for regrinding of all instruments.

These accessories are contained in the sleeve pocket leather fat-crafted.

The sheath while maintaining the traditional lines, is completely reversible (both the pocket that the passer can be disassembled and applied on the other face of the sheath) and to secure the side which holds the knife has the ambidextrous release. The sheath is handmade by a master saddler leather first-aged choice.

And 'possible to bring the sheath is vertical to the belt connected to the leg, which in a comfortable horizontal position, the shoulder or stopped at the waist with a long belt kit with buckle and snap hooks.

The handle in cocobolo oiled is long enough to allow the use of the knife as a little machete or chopper and thin enough to allow precision cuts.

The blade is in the classic Bohler N690, an excellent steel chrome molybdenum vanadium and cobalt which deserved to become a standard in technical and professional cutlery.

The finish is satin.

The Culter Venatorius is dedicated to all those who wish an Extrema Ratio as batting partner.
