Extrema Ratio Caimano Nero N.A. Satin has the same characteristics of the popular Caimano Nero N.A., 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 4 mm thick and has an asymmetrical spear point shape. The serrated part of the edge allows to cut highly resistant cables and fabrics without losing its sharpening. The blade has a satin finish.
The grip is made of two anodized anticorodal aluminum handle scales in black.
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.
