Since 1997, Extrema Ratio, an Italian company based in Prato, has designed, manufactured, and sold high-performance combat, military, kitchen, hunting, and tactical knives, earning it an unmatched reputation for excellence in the military and tactical knife sector.
The business takes great pleasure in its use of design, materials and quality to produce high-end goods that adhere to the strictest military specifications.
A 3D system is used by the Extrema Ratio design team to develop new models and prototypes. Then, each hunting, tactical pocket knife design is carefully examined and put to the test in the field. The best materials are now selected for their strength, usefulness and beauty. The Extrema Ratio team of craftsmen then hand assemble, hand finish, and hand examine each kitchen, tactical or military knife.
The material used to make all of the knives is N690 Cobalt Stainless Steel, which comes from a small Austrian plant and is frequently used to make surgical instruments. This steel and their tempering techniques result in a steel that is very strong, flexible, and able to take and maintain a razor-sharp edge. Fixed blade knives come with handles constructed of Forprene, a grip polymer that offers a very secure and comfortable grip even when wet. The best materials are utilized throughout the folding line of tactical or military knives to ensure dependability and lifespan. The shell is composed of an extremely robust anticorodal alloy.
Knives produced by Extrema Ratio are developed in close collaboration with the Italian and international armed forces. No design compromises are taken in order to obtain the highest performance and functionality. As a result, Extrema Ratio tactical, combat and military knives are well renowned for their exceptional durability and ability to withstand the strictest military standards.
