Caimano Nero N.A. is the non-automatic version of the tactical knife that Extrema Ratio has supplied to the G.O.I. (Operational Raiders Group) of the Italian Navy.

The blade is a 4 mm thick asymmetrical spear point. The serrated part of the edge allows to cut highly-resistant cables and fabrics without losing its sharpening.

The bottom part of the handle is designed to enhance the grip for a rapid extraction of the knife from the pocket. It is also equipped with a hard-metal glass breaker.

The DLC-coated titanium clip can be positioned in three different angles on both sides allowing to conceal the knife as much as possible inside the pocket.
