Extrema Ratio

Extrema Ratio

Extrema Ratio, located in Prato, Italy, has been designing, manufacturing and selling high performance combat knives since 1997 enjoying a reputation for excellence that is unsurpassed in the military and tactical knife industry.

The increased capacity through the years enabled Extrema Ratio to extend its operations. As part of this effort, the company moved in 2004 to a new 600 square meter facility in order to meet the market demand and the company quickly established itself as one of the country's leading cutlery manufacturers.

Extrema Ratio serves military and law enforcement communities as well as commercial markets and the knives are well known and sought after all over the globe.

The company prides itself in design, material and quality to deliver a high end product that meets the most severe mil-standards.

The production based on modern cutting edge technology is combined with traditional craftsmanship and the result is the pinnacle of this synthesis. The Extrema Ratio design team uses the 3D system to design new models and create prototypes. Each knife design is then meticulously inspected and then field tested. At this point the finest materials are chosen for durability, function and beauty. Each knife is then hand assembled and hand finished and inspected by Extrema Ratio team of craftsmen.

First class handwork and well-selected material have contributed to form the image of the Extrema Ratio trademark all over the world.
