Extrema Ratio

Extrema Ratio, since 1997, specialises in designing and manufacturing high quality combat knives, tactical folders and diving knives. This Italian company enjoys an excellent reputation, being unrivalled in the military and tactical knives segment. It supplies, among others, the GIS (Gruppo d'Intervento Speciale) and the 9th Special Battalion Col Moschin. The excellent design, materials used and high quality of workmanship enable the company to deliver top quality products which meet the strictest MIL-Standards.

All knives are made from N690 Cobalt stainless steel, used in the manufacture of surgical instruments, which comes from a small factory in Austria.
