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.

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.

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.
