Extrema Ratio S.a.s.

Shared threads run through all of our product line, tieing it together, and attest our core principles. All items are designed and manufactured expressly to solve problems – they’re tools for professionals. We keep to a limited number of product types, each of them tailored to a specific kind of user, and feel confident in the proven effectiveness of them all. That’s why we favor improving on our established designs over needlessly fashioning new ones. Our knives change and grow. By interacting with our customers, absorbing their invaluable experience and expertise, we’re empowered to make our products evolve. Having collected a wealth of knowledge thanks to our partnerships with Armed Forces and Law Enforcement Agencies – in Italy and worldwide – we have learned to develop products fit for demanding professional users. We design, prototype, test and manufacture knives for military, lawenforcement and rescue use. We have both the capability to produce custom items to specifications and to develop new designs to meet our clients’ specific needs.
