The Caimano Nero N.A. is the non-automatic version of the tactical knife that Extrema Ratio supplies to the G.O.I. delivered to the Italian Navy's (Operational Raiders Group). The blade is a 4 mm thick asymmetrical spearpoint blade. The serrated edge allows cutting high-strength cables and fabrics without losing sharpness. The lower part of the handle is designed to optimize the feel and allow for quick removal of the knife from the pocket. It is also equipped with a hard metal glass breaker. The DLC-coated titanium clip can be positioned at three different angles on both sides to hold the knife in the pocket as optimally as possible.
