Satre is a small, light and extremely resistant fixed blade knife. Given its characteristics, it is used in a wide range of disciplines and uses ranging from survival activity, bushcraft or as an element of an EDC (Every Day Carry) kit.
It was designed in collaboration with Daniele Dal Canto, Master Advanced F.I.S.S.S. (Italian Federation of Sports and Experimental Survival).
In Neck Knife mode, through the use of a paracord 550 cord, it is possible to keep it around the neck by keeping the knife vertically with the handle facing downwards. The metal eyelets on the sheath made of pre-shaped Kydex allow the application of both the lanyard and the accessory holder.
The full-tang skeletonized structure allows you to customize the knife using paracord as a coating for the handle
This Black version uses the Böhler N690 heat treated at 58 HRC. This material is chosen for its resistance to oxidation, the durability of the wire and above all the reliability it has shown over the years.

ExtremaRatio - Satre - S600 Black EXP Dark - Neck Knife
Satre is a fixed blade knife of small dimensions, light and extremely resistant. Given its characteristics, it can be used in a wide range of disciplines and uses ranging from survival activities, bushcraft or as an element of an EDC (Every Day Carry) kit.
It has been designed in collaboration with Daniele Dal Canto, Master Advanced F.I.S.S. (Federazione italiana survival sportivo e sperimentale) instructor.
In Neck Knife mode, through the use of a 550 paracord lanyard, it is possible to hold it around the neck keeping the knife vertical with the handle facing downwards. The metal eyelets on the sheath, made of pre-shaped Kydex, allow the application of both the lanyard and the accessory holder.
The full-tang skeleton structure allows to personalize the knife using the Paracord as a coating for the handle.
The Black S600 version uses Böhler S600 steel. This steel is used in industrial manufacturing to make metalworking tools and in mold making.
The high content of Molybdenum, Tungsten and a good presence of Vanadium in its chemical composition, give it excellent qualities of hardness, wear resistance and toughness. The presence of Cobalt favors the formation of small carbides uniformly distributed, a characteristic that enhances and elevates wear resistance.
Satre S600 is hardened and cryogenically treated, thus reaching an exceptional hardness of 64 HRC. This gives it great wear resistance and the ability to guarantee the cutting edge of the wire for a long time.
Böhler S600 has 4.5% Chromium, which makes it a carbon steel and therefore can cause rust and oxidation if neglected. To better protect it from atmospheric agents, we have chosen the new external coating EXP DARK.
The high hardness and resistance to wear and abrasion, make this steel not easy to sharpen.

ExtremaRatio - Herring NE - Fairbairn Sykes Dagger - tactical knife
The Herring dagger is one of the most loved military knives by enthusiasts.
Its original name is Fairbairn Sykes or Commando Dagger and it was present in the endowment of the British Commandos.
A dagger that entered Italian history in World War II, thanks to the exploits of young soldiers of the 1st "Folgore" Reconnaissance Squadron, who were equipped with this weapon during Operation Herring. He has behind him a heroic piece of history that is rarely talked about, despite the fact that these young boys, thanks to their devotion to the cause and their courage, have written an important page in Italian history.
Extrema Ratio wanted to pay homage to this dagger trying to remain faithful to the original forms, while using the most modern production techniques.
The very special hand-made finish of the handle simulates the aging of brass and gives the dagger a dated look, similar to the original.
The dagger was developed in collaboration with the 185th RAO and adopted as a ceremonial commemorative dagger for the 20th anniversary of the regiment's establishment and the 75th anniversary of the Herring mission.
The knife is equipped with a polymer case with historical frieze of the F Squadron, leather / kydex sheath with brass tip and two commemorative scrolls.
PLEASE NOTE:
NE version, simulacrum replica with rounded tip and blunt blade, to allow free sale and possession according to the current regulations in force on the Italian territory.We warn that any subsequent modifications and sharpening made to the blade modify the status of simulacrum of the Herring NE. In this case it will be subject to the regulations in force in the respective countries. Furthermore, these changes will void the Extrema Ratio warranty.

The Extrema Ratio Frame Rock is a new knife, based on the Ti-Rock project, a successful frame-lock knife made by Extrema Ratio in 2016 exclusively for Coltelleria Collini.
The Extreme Ratio Frame Rock is characterized by the titanium handle that offers great resistance while being very light. The integrity of the frame-lock locking system is guaranteed against wear by an easily replaceable hardened steel insert.
Unlike its drop-point predecessor, the Rock frame has a spearpoint blade 75 mm long, 6.0 mm thick, equipped with fuller for further lightening. The blade is made of Bohler N690 steel, heat treated to a hardness of 58 HRC. The same is available in black finish with DLC or satin finish.
To make the opening even more fluid and free of uncertainties, the blade rotates on ball bearings. This mechanism allows the user to adjust the force necessary to release the blade from the closed position.
The shape of the reversible clip allows a hidden port in the pocket, making the knife not visible from the outside. The large, solid handle and the well-proportioned blade allow this knife to tackle demanding tasks. Frame Rock weighs less than 200g, making it somewhat light for such a sturdy knife. It is supplied inside an ABS box.

ExtremaRatio - Resolza 10 - Black - pattada knife
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.

SILENTE is the name of the knife taken from the motto "SICUT NOX SILENTES" by N.O.C.S. Central Security Operations Unit, special anti-terrorist unit of the State Police.
SILENTE was presented to the Department, the Authorities, the Minister of the Interior and the Chief of Police on the occasion of the forty-year ceremony of the foundation of the NOCS.
SILENTE is a unique model of its kind that fulfills equally unique needs: the handle is divided into two parts and creates the handle of a clamp placed in the end of the handle. With it, in addition to taking on everything that has the appropriate dimensions, it is possible to cut wire, wire, steel cables, etc. and last but not least, it can be used as a window breaker, given the tungsten carbide insert at the end.
The sheath protects the cutting edge during all these uses, allowing it to be used safely, but it can also release the blade with a fast and silent retention system. Adaptable to thigh use and applicable to the M.O.L.L.E system, it is integrated into the operator's equipment using the least possible space.

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.

ExtremaRatio - SERE 2 - GOI Gruppo Operativo Incursori - rescue knife
S.E.R.E. 2, adopted by the Operational Group of Italian Navy Incursors, is the development of the S.E.R.E. 1, created by a study group composed of Special Forces operators, martial artists and experts in survival techniques. This variant 2 has been revised according to the needs expressed by the Department.
The acronym S.E.R.E. refers to the four principles "Survival, Evasion, Resistance and Escape" which make up the training program provided to military personnel at high risk of capture.
The S.E.R.E. 2 is suitable for both tip and cut use. The unique grip, unlike the classic blades of this type, is fixed between the index and the middle, thus forming a single axis from the tip of the blade to the user's wrist, allowing its use also in reverse grip. The handle has the same ergonomics as the butt of a firearm; this grip allows an instinctive and immediate use, being able to easily integrate the training in the training activity.
The geometry of the tip ensures maximum penetration, at the same time its axial profile with a triangular base protects its resistance. The design of the blade has on one side a partially serrated profile to favor the cutting of cordages, and on the other hand a classic cut or straps that, unlike the previous model, has re-sharpening and interchangeable blades.
The central loop, which has the dual function of lightening and turn-crickets, recalls the maritime origins of its creators. The peculiarity of the knife is that it has been specifically designed to be used even without the handle; the two holes in the part dedicated to the handle facilitate assembly.
The kydex sheath has a basic retention that can be used alone for operators who need extremely fast knife use, and a removable locking lock if necessary. The knife is supplied with double safety for ambidextrous mounting. An insert with a flat-blade screwdriver is available as an accessory. Comes with belt clip for belt fastening and paracord for fixing on the M.O.L.L.E. system.
"Using the gun, knife or other weapon for us is the same thing: it's just the extension of the hand." Quote from a commander of the ward.

ExtremaRatio - BF2 V Stone Washed Knife - Sailing Knife
This knife was designed and perfected in every detail for its primary use in the marine environment. The blade has a flat rounding that allows symmetrical cutting work with wider support. The tip, on the other hand, which is thick and durable thanks to the tanto version, allows greater penetration and a sharper, more precise cut. The stone washed finish process facilitates locating in the marine environment.
The structure of the handle, made of anodized anticorodal aluminum, features a design with milling in concentric circles and lightening and anti-slip perforations so as to facilitate rinsing from saltiness. A small slot is cut into the middle of the cheek piece to allow for tightening or releasing smaller shackles. BF2 V is equipped with reversible clip; adjusting screw retainer for closing and opening the blade; 70-mm. knot shock ankle with fastening mechanism; and correctable. The presentation of the BF2 V took place on the Amerigo Vespucci School Ship.

The restyling of the famous "Paratrooper dagger dagger mod.1939", an important piece of Italian military history.
The knife, although borrowing the line, the structure and the proportions of the original, has been strengthened, enriched with functional modifications and made with materials with modern military specifications.
Unexpectedly, the result of these few modifications is an extremely functional and effective dagger, absolutely competitive with the best contemporary military knives.
The sheath is rigid from the ankle, in the typical manner in which the bayonet is carried by Italian paratroopers.

La rivisitazione di un classico, il tributo ad un veterano, il restyling di uno dei pugnali da guerra più largamente distribuiti ed impiegati nel secondo conflitto mondiale: il MARK 2.
Prodotto dalle aziende storiche statunitensi, in innumerevoli varianti ma sempre fedele alle specifiche originali del contratto U.S.NAVY nella forma generale, questo pugnale rimane il preferito dei nostalgici e dei tradizionalisti che si affidano soltanto a strumenti “battle tested”.
I produttori si sono spesso cimentati nell’impresa di modernizzare questo pugnale con risultati non incoraggianti tanto che il modello tradizionale occupa ancora una posizione di rilievo nei principali cataloghi.
Extrema Ratio si cimenta in questo ambizioso progetto con l’obiettivo di mantenere le caratteristiche peculiari dell’originale per effettuare soltanto modifiche funzionali mirate all’incremento delle prestazioni.
Acciaio inossidabile al cobalto per la lama, AISI 303 e AISI 304 per le altre componenti, nel manico il Nylon caricato con fibra di vetro ha preso il posto del cuoio a rondelle.
L’ergonomia dell’originale è stata mantenuta ma tutte le parti strutturali sono state sovradimensionate per farne un massivo e performante coltello multiruolo.
A livello concettuale, le modifiche più significative sono mirate a risolvere i tradizionali “punti deboli” del modello originale: la possibilità di effettuare lo smontaggio da campo senza utensili, la punta con profilo Bowie modificato dritto (più facile da riaffilare) e le scanalature sull’impugnatura “a botte”, che aiutano a percepire anche al buio il verso della lama e incrementano geometricamente la tenuta nei movimenti di torsione (effetto cacciavite).
Altre piccole modifiche sono i fori per il laccio di sicurezza (di cui l’originale era sprovvisto) e i fori sulla guardia che permettono di legare il pugnale ad un bastone da usare come lancia da sopravvivenza.
Il tradizionale scolasangue è stato “vigliaccamente” sostituito con il tipico “side groove” Extrema Ratio per motivi che confessiamo essere puramente estetici: a noi piace così…
Il resto, effettivamente, andava bene com’era…e così lo abbiamo lasciato.
Le prime due versioni sono il classico nero Extrema Ratio e il Desert Warfare, quest’ultimo alloggiato in un fodero coyote HCS specificatamente studiato per le SOF.
Il fodero della versione nera è standard, con innesto automatico del coltello, pattella e cinghia cosciale per il fissaggio al fianco, compatibile con sistema MOLLE.4357-D -

ExtremaRatio - RAO C - N690Co & Aluminum Tactical Grey - folding knife
Thanks to its structure, RAO C is a tool that despite its small size, manages to guarantee the same qualities of robustness and reliability as its big brother while offering better portability and manageability.
The locking mechanism on opening is particularly strong as it is assisted by a safety system that turns it into a true fixed blade. The primary safety on the blade is activated by raising and lowering the locking pin. To provide the user with maximum safety in use, a practical and quick secondary safety has been applied, which can be activated simply by moving the locking pin horizontally.
For the purpose of lightening the steel frames, a template was laser-cut from the profile of the RAO C, which was then used to make a gadget that is delivered with the knife.

ExtremaRatio - Satre Expeditions - Utility Neck Knife - Knife
Satre Expeditions, as well as the Satre model from which it derives, is a fixed blade knife of small dimensions, light and extremely resistant. Given its characteristics, it can be used in a wide range of disciplines and uses or as part of an EDC (Every Day Carry) kit.
It has been designed in collaboration with Daniele Dal Canto, Master Advanced F.I.S.S. (Federazione italiana survival sportivo e sperimentale) instructor. In Neck Knife mode, through the use of a 550 paracord lanyard, it is possible to hold it around the neck keeping the knife vertical with the handle facing downwards.
The metal eyelets on the sheath, made of pre-shaped Kydex, allow the application of both the lanyard and the accessory holder.
The full-tang skeletonized structure, allows you to customize the knife using Paracord as a coating for the handle.
Satre Expeditions uses Böhler N690 steel heat treated to 58 HRC with MIL-C-13924 burnishing and stone washed surface treatment (Dark Stone finish). It comes with a desert-colored pre-formed kydex sheath on which you can attach the Firesteel for lighting fires (provided inside the box).

ExtremaRatio - Frame Rock Titan Knife - Blue Satin - PRIVATE COLLECTION - folding knife
Knife withdrawn from a private collection - In like new condition - Never regrind - Checked and certified by our in-house Coltelleria Collini laboratory.
The Extrema Ratio Frame Rock is a new knife, based on the Ti-Rock project, a successful frame-lock knife made by Extrema Ratio in 2016 exclusively for Coltelleria Collini.
The Extreme Ratio Frame Rock is characterized by a titanium handle that offers great resistance while being very light. The integrity of the frame-lock system is guaranteed against wear by an easily replaceable hardened steel insert.
Unlike its drop-point predecessor, the Rock frame has a 75mm long, 6.0mm thick spearpoint blade fitted with a fuller for further lightening. The blade is made of Bohler N690 steel, heat treated to a hardness of 58 HRC. The same is available with a black finish with DLC treatment or satin.
To make opening even more fluid and without uncertainty, the blade rotates on ball bearings. This mechanism allows the user to adjust the force necessary to obtain the release of the blade from the closed position.
The shape of the reversible clip allows a hidden port in the pocket, making the knife not visible from the outside. The large and solid handle and the well-proportioned blade allow this knife to tackle heavy tasks. The Frame Rock weighs less than 200g, making it somewhat light for such a sturdy knife. Comes inside an ABS box.

ExtremaRatio - N.K.1 Neck Knife - SanMai V-TOKU2 - Limited Edition - NK1 - Knife
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.ER-NK1-CC -

ExtremaRatio - Resolza 10 - Stone Washed - pattada knife
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.

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.

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.
