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. 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.

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 .

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.

W.R. Case & Sons Cutlery Company è stata creata a inizio secolo, in un tempo in cui i coltelli tascabili erano indispensabili tanto quanto un orologio. Nel corso degli anni l'azienda si è affermata come una azienda leader nel lancio sul mercato di materiali nuovi e design innovativi.

Le radici dell'azienda risalgono al 1889, quando dei fratelli intraprendenti, William Russell (W.R.), Jean, John e Andrew, nella famiglia Case iniziarono a vendere coltelli artigianali dal retro di un furgone nella parte settentrionale dello stato di New York. Nel gennaio 1900, i fratelli costituirono la Case Brothers Cutlery Company, fondando così il primo marchio di famiglia Case.

J.R. Case, che chiamò l'azienda con il nome del padre, W.R., costituì la W.R. Case & Sons nella forma in cui oggi è conosciuta. Quando nel 1905 l'azienda si trasferì a Bradford, Pennsylvania, i quattro fratelli Case avevano fatto dei loro marchi di famiglia i nomi più rispettabili della coltelleria in America.

All'inizio della prima guerra mondiale, il governo fece appello alla Case per la produzione di coltelli militari per i combattenti americani. Durante il volo della “Molly Brown” nel 1965, agli astronauti Gus Grissom e John Young utilizzarono coltelli Case speciali nella missione spaziale della NASA.  Case ha raccolto ammiratori famosi e avidi collezionisti come l'ex Presidente americano, Dwight D. Eisenhower e la star della musica country, Randy Travis.

Directly derived from military specifications, this fold has been developed to replace a fixed blade in use.

To achieve this result, very strong materials, high thicknesses and a solid and safe opening and closing system were used: the back lock.
The knife is equipped with a manual safety device which confers maximum safety in use and reduces the risk of accidental closure in manieradrastica.
The safety device, if inserted in closing, prevents the knife from being turned against itself in the case of subtraction.

Materials and workmanship:

All parts of the knife are machined from high-precision CNC machines, while assembly, adjustment and sharpening are carried out by hand.
The blade is made of cobalt N690 stainless steel, a steel with very high resistance to mechanical stress, cutting capacity, thread strength and corrosion resistance. The grinding is flat and the hardness is 58HRC.
The grips of the handle are in Anticorodal, an aluminum alega with high resistance to mechanical stress and oxidation.
The tang, in hardened N690, is an effective emergency crystals. All screws, pins and clips are in burnished stainless steel. The blade, the lever and the shank are covered with Testudo treatment, very resistant to abrasion and oxidation. The cheeks are black anodized.
