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.

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.

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.

Until the early years of the '900 was commonly carry in your pocket a boxcutter by utility but, with a succession of cases of "misuse" of these objects, the law imposed the cutting or cutting-off of the tip of the blade to limit the harmfulness . Someone thought it well to take full advantage of the cutting edge of a blade typically already checked, taking as a pocket knife a straight razor, which became for a certain period of time a feared defensive tool.

The Task series has been designed for all everyday cutting jobs.

The blade is partially symmetrical with a flat edge on both sides. The recessed part of the blade after the guard, which separates the sharpened part from the handle, has been realized by housing the index finger during use, creating a grip point near the sharpened part for a better control during the use of the knife.

This feature, together with the support grip on the back of the knife, allows a better grip while avoiding the sliding of the hand on the blade. In this way it is possible to carry out most of the cutting work by applying a higher pressure if necessary.

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.

The design of this military knife, sponsored by COFS (Special Forces Operative Command) in the person of General Bertolini, had already been suggested by some collectors of white weapons of the time. The restyling of the famous "paratrooper assault dagger mod. 1939 ", constitutes an important piece of Italian military history.

The knife, while borrowing the line, the structure and the proportions from the original, has been strengthened, enriched with functional modifications and made with materials with modern military specifications. The result of these few modifications is an extremely functional and effective dagger. The sheath is ankle-shaped to be worn as Italian paratroopers usually wear a bayonet.

The 39-09 COMBAT version is the compact version with 160mm blade and side sheath.
