In 1943 a battle was fought between the U.S. and Canadian First Special Service Force and German troops in Italy. Known as the Battle of Monte la Difensa, the courageous performance of the U.S. and Canadian forces on this occasion was essential to the final Allied victory in Italy.

When Canadian Special Forces commissioned Spartan Blades and master cutler William Harsey to produce a blade for them, we knew we wanted to create something special. Our goal was to create a knife that would serve the Special Forces for years to come, both in the northern woods of their homeland and in missions around the world. The result was the Spartan Harsey Difensa, named after the infamous and hard-fought victory achieved through cooperation between Canadian and U.S. forces.

The name refers to the excellent use of this custom tactical knife in the field and on the battlefield. The spearhead profile of this handcrafted knife is flat, with a tapered top edge that provides excellent tip strength, balanced penetration, and cutting power.

The full tang and handle of the Spartan Harsey Difensa allow for neutral balance in the user's hand. Combined with the ergonomic Micarta canvas handle, modified from our Model II, with no rear joints, this custom combat knife provides the griper with a comfortable and secure grip in both dry and wet conditions.

After more than 40 years of service in the U.S. Army Special Forces, Curtis Iovito and Mark Carey founded Spartan Blades LLC in North Carolina. Curtis, who had already been designing and drawing knives for his friends in the Special Forces for years, and Mark, who had always been involved in military and tactical equipment when he served in the "Green Berets," decide to combine their skills and passion with the goal of building innovative and functional knives using the highest quality materials and made entirely in the United States.

The Mission Team 21 is a no-nonsense tactical knife that can also easily carry out many activities in the field. The handle has been designed to remain in the operator's hand even in difficult situations thanks to the finger grooves, finger guard and jimping. If necessary, the knife can also be used in survival situations.

Created with the guidance of Bill Hill (Command Master Chief-Seal Team 3 retired with over 30 years of real-time experience), this design has produced a great field tool for any theater. Very nice aesthetically, feels good in the hand and always performs at its best.

Selvans Expeditions, as well as the Selvans model from which it derives, was born from the collaboration between Extrema Ratio and the Master instructor F.I.S.S. (Federazione Italiana Survival Sportivo e Sperimentale) Daniele Dal Canto. This tool is the result of the modification of the ONTOS, military survival knife, realized in order to accentuate and maximize the performance of the knife.

Selvans Expeditions uses Böhler N690 steel heat treated to 58 HRC with MIL-C-13924 burnishing and stone washed surface treatment (Dark Stone finish). The handle has been lengthened and the blade weighted to promote effective cutting strokes. It comes with a desert Cordura sheath with MOLLE system, equipped with a mini pouch containing paracord with flammable filament that can be used in case of emergency and/or critical weather conditions and a Firesteel for lighting fires.

The survival kit (not included and purchasable separately) has been optimized and includes whistle, chainsaw, drinking pads, compass, brass wire, flintlock, flashlight, paracord 2,5 mt. and sharpener.

Japanese steel blends with Italian excellence

For this 2020 collaboration, exclusive of Collini Cutlery, we have decided to propose a series of best sellers produced by Extrema Ratio. Knives made with the famous San Mai steel produced by Japanese Takefu Steel. Specifically, we used V-Toku2 carbonaceous at 62 / 63HRC for the central plate and SUS410 stainless steel for the two external plates, in order to guarantee a very high cutting capacity, penetration and sealing of the wire together with an easy regrinding. and maintenance but at the same time the blade has a remarkable resistance to corrosion and an important increase in resilience given by the type of external steel and by the laminated structure.
Selvan model: for this First Production Run a run of 5 pieces numbered from 1 to 5 was created.

The Selvans was born from the collaboration between Extrema Ratio and FISSS (Italian Federation of Sports and Experimental Survival). The project consists of modifying the Ontos, a military survival knife, to accentuate and maximize the performance of the knife as a hiking tool.

The handle has been lengthened and the blade weighted to favor the effectiveness of the cutting strokes and to make more use of the inertia of the stroke.

Intended use: Heavy Utility
Type of production: Industrial
Production Lama: Italy
Blade: integral, laminated Japanese steel (San Mai) with V-Toku2 (carbonaceous) cutting edge at 62 / 63HRC and SUS410 (stainless steel) external scales

Notes: Numbered edition - cardboard box with Extremaratio logos and certificate - being the cutting edge in carbon steel it is advisable, in order to keep the blade in perfect condition, to protect the edge with a light surface of oil.

As in the ancient Japanese Samurai swords.

The rolled steel - imported into 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. In fact, as early as 1100 the expert Japanese blacksmiths combined different materials together to give the Katana swords incredible cutting capabilities combined with a resistance and flexibility previously unknown. It is thanks to this revolutionary construction technique that Samurai swords have been preserved to this day, becoming one of the most fascinating objects made by man. Following this tradition applied to modern metallurgy, today we are 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: These are different types of metals bonded together to create a composite that encloses and intensifies the strengths of the metals individually taken:
- Longer tool life
thanks to the use of very high quality steels with high carbon content (VG10, CoS, Shiro) or sintered (SPG2), in the heart of the sheet (Core Steel), the blade, once hardened, achieves decidedly hardness and cutting performance higher than those achieved with the use of traditional steels.

- Greater resilience
built on the principle of Japanese swords, 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 side facing (Stainless Steel).

- Better corrosion resistance
the steel used for the external layers (Stainless Steel) guarantees the blade a high resistance to corrosion. The combination of the two or more materials used by Takefu Steel generates, on a galvanic level, a structure that improves corrosion resistance even on the wire.

- Easy processing even after heat treatment
although steel normally becomes harder after quenching, the lateral steel used in multilayer processing does not lose its softness and allows easy processing, drilling or welding even after heat treatment. For an optimal performance of the blade, cryogenic treatment is recommended.

- Improvement of the aesthetic result
The knives made with multi-state steel or with a damask pattern at the end of the processing are aesthetically elegant, refined and highly appreciated by collectors all over the world.

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.
