Extrema Ratio knives are a part of equipment of many special military units of Italy, the police and rescue services. Each model is developed very carefully and undergoes a series of rigorous tests before it is put into production. Extrema Ratio cooperates with the University of Perugia, where scientists conduct a number of studies determining the ergonomics of Extrema Ratio products and methods for improving it. The office of Extrema Ratio is located in Prato, Italy.
Both Extreme Ratio tactical knives and EDC knives are distinguished by impeccable quality. Most knives are made of Austrian steel N690, which is famous for its high content of molybdenum and cobalt and is highly corrosion resistant. Due to this, N690 steel has increased strength and resists shock loads well. The most popular Extrema Ratio knives are Fulcrum, Col Moschin, RAO, Adra and others. Extrema Ratio also produces several lines of tactical folding knives: BF (basic folder), MF (medium folder), BD4, BD2 series and other knives. In our store you can buy Extrema Ratio tactical knives, as well as folding and EDC knives of this brand. MyGoodKnife is the official distributor of Extrema Ratio.
