ExtremaRatio - Waki Black Machete Knife - Tactical Knife
The product is an elaboration of the Japanese Wakizashi sword, a typical blade 30 to 60 centimeters long, which the Samurai carried at all times in contact with the body, where the Katana was carried exclusively in battle. The blade produced from Boehler N690 steel is hardened to 58HRC while the handle is made of forprene, an elastomer that falls under the "NATO standard" for resistance to extreme conditions. The Waki Black comes with a cordura, military-derived scabbard that ensures safe carrying of the razor-sharp blade and its protection from shocks that could reduce its efficiency. The scabbard is also equipped with the MOLLE system that allows it to be carried on tactical vests and general belts.

ExtremaRatio - Selvans Expeditions - Heavy Utility Survival Knife - knife
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.

ExtremaRatio - Selvan Heavy Utility Survival Knife in San Mai V-TOKU2 - Limited Edition - knife
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

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.For more information: collinisteel

HISTORICAL SUMS ON THE DEPARTMENT:
The 185 ° RAO of the '' Folgore '' is a department with an ancient tradition, but very new. In fact, it was born on April 3, 2000 following the reconfiguration of the 185th terrestrial paratroop artillery regiment. Based in Livorno, it is an atypical department of the artillery weapon, currently inserted in the Special Forces basin.Entirely composed of voluntary personnel, the 185th RAO selects its components through the passing of a physical test and a qualification course on modules '' with increasing difficulty ''. The tasks entrusted to the RAO's men are many, but all very delicate: it is about gathering information on enemy objectives and 'passing them' to one's command. More generally, it can talk about '' recognition in sensitive areas ''. '' It is therefore evident - they stress to the Army - that the activity of the acquirer takes place mainly in hostile territory, in small self-sufficient nuclei that act in isolation ''.
RAO paratroopers are specialists in '' infiltration and exfiltration '' techniques and are able to move in the operating area '' for up to 8-10 days without external supplies ''. They know how to 'escape from capture, escape and escape from an' enemy controlled area '' and, above all, as '' identify, determine and evaluate objectives '' of strategic interest. Since 2002, the year of reconfiguration, the 185th Regiment detachments have operated in all the hottest operational theaters: from the Balkans to Afghanistan, to Iraq. Here they mainly carry out surveys for medium and long-range information purposes and for monitoring the area of responsibility of the Italian contingent.
