HISTORY
The Tengu takes its name from a mythical creature of Japanese folklore that is represented with both human and raven features, they had the reputation of being great warriors and legends say that some founders of martial arts were trained by them.

- It is designed to be used in many different grips, but is especially effective in the reverse grip.
- Designed to be carried in a variety of ways, whether as a neck knife, under shirt, clipped in a pocket or around the waist using optional systems such as Ulti-Clip or Tek-Lok or various M.O.L.L.E. type attachments.
- With its thickness of 5.5 mm. is extremely robust and thanks to the shape of the handle is comfortable even by those with large hands or those who want to use it with tactical gloves.
- The blade is compact, robust and very functional for both precision cutting and hard materials thanks to the serrated part on the back. The tanto-shaped tip is very robust and optimal for engraving work.

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.

ERMES is the commemorative knife developed in collaboration with the Special Operations Helicopter Regiment (R.E.O.S.) which is part of the Army Aviation Command.

The R.E.O.S. is the operational unit of helicopters in support of special forces composed of personnel specifically trained and equipped to support military activities in any operational context.

The stylized guards of the knife represent the wings present in the heraldic coat of arms of the unit. The steel used is the reliable Bölher N690Co heat treated to 58 HRC. Fiber Reinforced Nylon (FRN) polyamide polymer was chosen for the handle. The hybrid Kydex and fabric sheath is equipped with belt or harness attachment with MOLLE interface system.

It is available in two versions:
"ERMES SATIN ORDINANZA" with satin finish blade and ABS case.
"ERMES BLACK OPERATIVO", with the burnished blade.

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.

Direttamente derivato da specifiche militari, questo chiudibile è stato sviluppato per sostituire nell'impiego un lama fissa.

Per raggiungere questo risultato sono stati impiegati materiali robustissimi, alti spessori ed un sistema di apertura/chiusura solido e sicuro come il back lock.

Il coltello dotato di sicura manuale che conferisce massima sicurezza nell'impiego e riduce in maniera drastica il rischio di chiusure accidentali.
La sicura, se inserita in chiusura, evita agli operatori militari o di polizia che nel caso di sottrazione il coltello possa essere rivolto contro di loro.

Materiali e lavorazioni:
Tutte le parti del coltello sono ricavate dal pieno da macchine a controllo numerico ad alta precisione mentre l'assemblaggio, l'aggiustaggio e l'affilatura sono condotte artigianalmente.
La lama in acciaio inossidabile al cobalto N690, un acciaio dalle elevatissime caratteristiche di resistenza alle sollecitazioni meccaniche, capacit di taglio, tenuta del filo e resistenza alla corrosione. L'arrotatura piana e la durezza di 58HRC.
Le guancette dell'impugnatura sono in Anticorodal, una lega di alluminio con elevate doti di resistenza alle sollecitazioni meccaniche ed all'ossidazione.
Il codolo, in N690 temprato, un efficace frangi cristalli d'emergenza. Tutta la viteria, i perni e la clip sono in acciaio inox brunito. La lama, la leva ed il codolo sono ricoperti con trattamento Testudo, molto resistente all'abrasione ed all'ossidazione. Le guancette sono anodizzate nere.

La serie Task stata studiata per tutti i lavori di taglio di uso quotidiano.

La lama parzialmente simmetrica con arrotatura piana su entrambi i lati. La parte incavata della lama dopo la guardia, che separa la parte affilata dal manico, stata realizzata per alloggio del dito indice durante l'utilizzo, creando un punto di grip vicino alla parte affilata per un miglior controllo durante l'utilizzo del coltello.

Questa caratteristica, insieme al grip d'appoggio sul dorso del coltello, permette una miglior presa evitando al contempo lo scivolamento della mano sulla lama. In questo modo possibile effettuare la maggior parte dei lavori di taglio con una pressione superiore.
