The Extrema Ratio Nightmare is a karambit folding knife with specialised rescue features. The karambit design retains its signature curved blade but adds the convenience of a foldi ng mechanism, making it more compact and portable. This allows the knife to be safely carried in a pocket or on a clip and deployed only when needed. Suitable for rescue work due to its functionality and versatility. Named in collaboration with the Monaco special intervention units' development and consulting team, this knife includes a durable, replaceable industrial-grade cutter blade, a reversible pocket clip, and a glass breaker positioned within the finger ring.
