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.
