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.

Zero Tolerance and Rick Hinderer teamed up to build the new 0562 with its exclusive Hinderer "slicer" grind.

The ELMAX® powdered steel blade with flat-ground “slicer” grind provides both slicing efficiency and a tough point. ELMAX is a third-generation powdered steel with virtually no nonmetallic inclusions. This means it offers an extremely uniform distribution of carbides for high wear and corrosion resistance. Zero Tolerance sharpens it to a hair popping edge and the ELMAX ensures it holds that edge for a long time, even under hard use.

The knife opens with a flipper and moves out of the handle on our smooth KVT ball-bearing opening system. A washer with caged ball bearings surrounds the pivot and makes opening the knife nearly frictionless; just pull back on the flipper and add a roll of the wrist and the 0562 is ready for action.

The handle has a G-10 textured scale in front and a stonewashed titanium back. For secure lock up during use, ZT uses a frame lock with hardened steel lockbar inserts and lockbar stabilization so the lock won't overextend.

The unique pocketclip is reversible (left/right) and enables extra-deep carry in the pocket. .

The Zero Tolerance 0808 is our latest piece of pocket technology. It's a collaboration between ZT and custom knifemaker Todd Rexford and is based on his Cesium model. But the technology here isn’t circuits and wires. Instead, it’s advanced-formula stainless steel and ZT’s smooth-as-silk KVT opening system.

The 0808’s blade is built of Crucible S35VN stainless steel. This powdered metallurgy steel is extremely fine-grained so it can be sharpened to a razor edge. Added niobium and nitrogen enhance toughness to resist chipping and provide excellent edge retention. Yet it’s also easy to re-sharpen.

Opening is fast and simple with KVT. Caged ball bearings surround the pivot to make the blade quick and easy to open using the built-in flipper. With KVT, the 0808 is as easy to open as any assisted knife, but without the need for a spring.

The 0808’s blade is paired with chamfered titanium handles that provide a solid, and very durable, grip. The sturdy frame lock has a hardened steel lockbar insert to offer extra-secure, extra-solid blade lock up. The reversible pocketclip enables you to carry comfortably left- or right-handed. Move over, iPhone. The 0808 deserves pocket space.

TACTICAL KNIVES MEET THE KITCHEN!
Extrema Ratio is delighted to apply the strict military standards to a range of professional kitchen knives.

The steel blade is the proven BOHLER N690, a steel enriched with chrome, vanadium, molybdenum and cobalt, hardened to the hardness of 58HRC. The handle is made of Forprene, an elastomer that is in the "NATO standard" for resistance to extreme conditions, and is completely removable from the blade; this makes possible a thorough cleaning and maintenance of the knife.

Each knife comes with its own sheath, also of military origin, which does not take into account the rules of hygiene but ensures safe transport dell'affilatissima blade and protection from shocks that could reduce efficiency. We recommend to use it only for the transport and in the event of long periods of inactivity.

Chiudibili Extrema Ratio:
Direttamente derivato da specifiche militari,questo apribile è stato sviluppato per sostituirenell'impiego un lama fissa.
Per raggiungere questo risultato sono stati impiegatimateriali robustissimi, alti spessori ed un sistema diapertura/chiusura solido e sicuro: il back lock.
Il coltello è dotato di sicura manuale che conferisce massima sicurezza nell'impiego e riduce in manieradrastica il rischio di chiusure accidentali.
La sicura, se inserita in chiusura, evita agli operatorimilitari 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 è in acciaio inossidabile al cobalto N690,un acciaio dalle elevatissime caratteristiche di resistenza alle sollecitazioni meccaniche, capacità ditaglio, tenuta del filo e resistenza alla corrosione.L'arrotatura è piana e la durezza è di 58HRC.
Le guancette dell'impugnatura sono in Anticorodal, unalega di alluminio con elevate doti di resistenza alle sollecitazioni meccaniche ed all'ossidazione.
Il codolo, in N690 temprato, è un efficace frangi cristalli d'emergenza. Tutta la viteria, i perni e laclip sono in acciaio inox brunito. La lama, la leva edil codolo sono ricoperti con trattamento Testudo,molto resistente all'abrasione ed all'ossidazione.Le guancette sono anodizzate nere.
