ABOUT
The Extrema Ratio NIGHTMARE KARAMBIT is a modern take on a centuries-old design, blending traditional functionality with tactical innovation. Originally inspired by farming tools from Southeast Asia, the karambit has evolved into a highly versatile knife - and the NIGHTMARE version elevates it further. Developed in collaboration with Monaco’s special intervention police unit (USIVP), this karambit adds rescue-focused features for practical everyday use. Whether you're cutting rope, webbing, seat belts, or working in confined spaces, the NIGHTMARE KARAMBIT is a powerful, reliable EDC choice. Its curved blade design, reinforced safety features, and integrated rescue tools make it ideal for first responders, and outdoor enthusiasts.
