ExtremaRatio - Sethlans Survival - N690 Stone Washed - Knife
The "Extrema Ratio Sethlans" is a fixed blade work knife created to face a wide range of situations, suitable for survival, bushcraft, prepping, but also as a backup blade. The Sethlans is available in two versions with two different types of steel.
Stone Washed version that uses Böhler N690 heat treated at 58 HRC, chosen for the reliability it has shown over the last 20 years due to its resistance to oxidation and durability of the wire.
The knife comes with G10 grips that feature the ergonomic design characteristic of Extrema Ratio handles. They can be removed by releasing the skeletonized structure of the knife, which allows maximum lightness with minimum thickness. For lovers of extreme customization, the full-tang structure allows the handle to be covered with a paracord cord.
The sheath is composed of a part in very light and minimalist Kydex. It can be disassembled and can be adapted for both left and right handed users. The addition of an optional belt clip allows the knife to be positioned both vertically and horizontally and makes the sheath much more versatile than the textile version. It is also equipped with a mini pouch with M.O.L.L.E. system. containing a double-sided stone for sharpening and a firesteel for lighting fires.

Supplied with handmade Kydex sheath and Wander Tactical certificate - Checked and certified by our in-house Coltelleria Collini laboratory.
In collaboration with Wander Tactical we have decided to propose their new neck knife, the Raptor model, in an exclusive version with a satin blade that uses the famous Japanese San Mai steel produced by Takefu Steel. Specifically we used, for the central plate, the CoS at 61.5HRC (Cobalt Special, mechanically considered 25% higher than the already highly appreciated VG10) and the 420J2 (at 56 HRC) for the two side plates in order to guarantee a very high cutting capacity, but at the same time a remarkable resistance to abrasion, resilience and resistance to oxidation.

Notes: Each knife is unique and handcrafted
As in the ancient Japanese Samurai swords.The rolled steel - imported into 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. 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 life of the cutting edge
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, at the galvanic level, a structure that improves the corrosion resistance even on the wire.- Easy processing even after heat treatment
although steel normally becomes harder after hardening, 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 with a damascus pattern at the end of the processing are aesthetically elegant, refined and highly appreciated by collectors all over the world.For more information: collinisteel

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: These are different types of metals bonded together to create a composite that encloses and intensifies the strengths of the metals taken individually:
- Longer tool life
thanks to the use of high quality steel with a high carbon content (V-Toku2, VG10, CoS, Shiro) or sintered (SPG2), in the heart of the sheet (Core Steel), the blade once hardened, reaches hardness and cutting performance significantly higher than that 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 lateral 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, at the galvanic level, a structure that improves the corrosion resistance also on the wire.- Easy processing even after heat treatment
although normally the steel becomes harder after hardening, the lateral steel used in multi-layer processing does not lose its softness and allows easy processing, drilling or welding even after heat treatment. For optimum performance of the blade, cryogenic treatment is recommended.- Improvement of the aesthetic result
The knives made with multistate steel or with damask pattern at the end of the processing are aesthetically elegant, refined and highly appreciated by collectors all over the world.ERCC-P-S-VT2 -
Wander Tactical - Smilodon Satin SanMai CoS & Black Green Micarta - craft knife
In collaboration with Wander Tactical we have decided to propose their heavy duty, the Smilodon model, in an exclusive satin blade version that uses the famous Japanese steel San Mai produced by Takefu Steel. Specifically, for the central plate we used the 61.5HRC CoS (Cobalt Special, mechanically considered 25% higher than the already highly appreciated VG10) and the 420J2 (at 56 HRC) for the two side plates in order to guarantee a very high cutting capacity, but at the same time a remarkable resistance to abrasion, resilience and oxidation resistance.

Extremaratio - Venom Stone Washed Half Serrated - Knife
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.

Extremaratio - Arditi Deluxe - Single-edged dagger - Limited Collector's Edition - Knife
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.

ExtremaRatio - Shrapnel OG Satin in San Mai CoS - knife
For this new exclusive collaboration with Extrema Ratio we decided to propose a best seller in the world of cutlery, the Shrapnel model. It's a satin blade version but the most important thing is that has been used, for the first time in Italy, the famous Japanese Steel San Mai produced by Takefu Steel. Specifically, we used the CoS (Cobalt Special, considered mechanically superior by 25% compared to the already appreciated VG10) for the central plate and the 420J2 (55 HRC) for the two side plates, in order to have a high cutting capacity, but at the the same time a remarkable resilience and resistance to oxidation.
A First Production Run of 30 pieces has been made.
SHRAPNEL OG is a truly versatile “back up” knife with marked combat qualities. Its leaf-shaped blade is flat ground at a characteristically low angle to a wide, extraordinarily sharp edge. The included hard sheath can be worn vertically, horizontally or obliquely (at a 45° angle). Tthe SHRAPNEL OG hilt design does not include a guard.

Clad Metal
It is a composite metal partly or entirely diffusion bonded together of different kinds of metals.
Metal composition shows higher performance which respective materials alone do not possess and the performance complements opposite characteristics of each material, that is "compound characteristics"Clad Effect on Cutleries
Toughness
Like Japanese swords, clad metal is hard to break or bend, thanks to the toughness as the hard steel part is clad with soft steels.
Easy to work on
Cladded structure is easy to apply on such works as forging, grinding, sharpening or polishing to make a sharp blade.
Improved corrosion resistance
Proper material combination generates electrical potential difference and it enhances the corrosion resistance on blade edge.
Better and long lasting sharpness
Steel after forging pressure makes the microscopic structure denser and improves the sharpness and ensures long lasting performance.
Resource saving
As high class steel is used only for necessary part, it is perfectly cost effective..
Easy distortion correction
As the steel is bonded with soft steel materials, its blade is hard to break and the distortion correction is easy.
Easy drilling and welding after heat treatment
Though the steel gets harder after heat treatment, the soft steel never loses its softness, enabling the material to be drilled or welded.
Design improvement
Laminated patterns or Damascus patterns appear from basis materials which are bonded with different kinds of metals.ERCC-SH -

Inaspettatamente, il risultato di queste poche modifiche è un pugnale estremamente funzionale ed efficace, assolutamente competitivo con i migliori coltelli militari contemporanei.
Il fodero è rigido da caviglia, alla maniera tipica in cui viene portata la baionetta dai paracadutisti italiani.
E' incluso il fodero da cerimonia per cintura, inclinato a 45° come l'originale.4255COL -
ExtremaRatio - Culter Venatorius - Limited Edition - Hunting Knife
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.
