Extrema Ratio
Extrema Ratio, located in Prato, Italy has been designing, manufacturing and selling high-quality combat knives since 1997. The company gained a great reputation for excellence that is unsurpassed in the military and tactical industry. The company prides itself in design, material and quality to deliver a high end product that meets the most severe standards. The first class handwork and well-selected material have contributed to form the image of the Extrema Ratio trademark all over the world.
The ONTOS (from the Greek language "the thing") is a pure field knife, solid and heavy but still compact. A portion of the upper blade is serrated in order to always have a sharp edge ready to be used.
In an emergency situation, when the soldier will leave behind the primary heavy equipment, he will always be able to carry the ONTOS thanks to its M.O.L.L.E. compatible nylon side sheath.
