A little more history about the brand
The company's history began in 1997 in Tuscany. The first Extrema Ratio workshops were opened in the city of Prato - the famous commercial and industrial center of Italy. For several years, the company fumbled along, producing a wide variety of types of cutting tools, from hunting knives to chef's hatchets.
As the brand's products are very popular, Extrema Ratio had to expand. In 2004, the production area was increased to 600 m². Despite the increase in sales, the company's management was aware that other Italian knife manufacturers were actively fighting to attract customers. It was necessary to find your own style, to stand out from competitors. They decided to focus on tactical models with a large reserve of force.
Peaceful kitchen utensils and short-lived EDC pouches have disappeared from the assortment, leaving only knives ready to survive the most aggressive use. The durability of Extrema Ratio products was assessed by military experts, one contract after another fell on the company. The weapons produced by the brand have become an integral part of the combat equipment of the Italian military forces. Cooperation with the active army turned out to be the best advertising. Personally using the dagger of a soldier of the famous GIS anti-terrorist unit, or becoming the owner of a dagger hanging on the belt of COFS special forces officers is the dream of every boy, whether he is 10 or 60 years old.
Extrema Ratio has gained the ability to supply the Italian Army, Police, through working with premium steel and branded handle materials.
They use N690 stainless steel which, according to the company website, is produced in a small factory in Austria. The factory may be small by Italian standards, but it belongs to one of the world's leading suppliers of high-quality tool steel, metallurgical group Böhler-Uddeholm AG. The structure of N690 resembles that of the American 440C with improved characteristics.
Austrian steel resists corrosion, sharpens well and withstands high impact loads. With proper heat treatment, the hardness of N690 reaches 60 HRC, and Extrema ratio masters get the most out of the steel. The company invests heavily in the development of processing technologies. Its tempering methods guarantee the strength of the blades and the long-term preservation of the sharpness of the cutting edge.
The creation of the Austrian metalworkers is not the only remarkable material used by the Italians. Forprene polymer is used on the handle of fixed knives, it provides reliable grip even with a wet hand and has shock absorption capacity. Tactical and combat folding knives also have remarkable handles. Most of their scales are made of high purity (98%) aluminum alloy. This alloy is appreciated by knife makers for its astonishing strength and superior corrosion resistance.
Another secret to success is the combination of advanced production technologies (like 3D modeling) with old-fashioned manual labor. After the knife is prototyped, it is rigorously tested in the field.
The company has developed a quality control system through which every product of the company passes.
Extrema Ratio knives range from small folding to large kurki, the company creates several variations of the same model.
Extrema Ratio's products are developed with advice from Italian and foreign military forces. The company's specialists do not sacrifice the practical qualities of a knife for the sake of beautiful design. Therefore, tactical, combat and military knives from Italians are distinguished by exceptional durability and meet the strictest requirements of army standards. Only then, after correcting the practical remarks, is a serial version of the product created. All knives are collected and adjusted manually by artisans.
