ABOUT
The Extrema Ratio KS KUKRI is a modern take on a legendary blade. Inspired by the iconic kukri used by the famed Gurkha regiments, this Italian-made version honors the traditional Nepalese design while enhancing it with modern materials and craftsmanship. Historically used for everything from clearing brush to combat, the kukri is known for its forward-curved blade that delivers powerful chopping force with the control of a long knife. Extrema Ratio’s interpretation retains that timeless effectiveness—perfect for outdoor work, survival, and heavy-duty tasks—while showcasing the company’s signature style and attention to detail. More than just a machete, the KS KUKRI is a trusted companion in any environment where performance matters.
