Extrema Ratio Knife Caimano Nero N.A.
The Caimano Nero N.A. from Extrema Ratio is the non-automatic version of a tactical knife originally developed for use by elite units of the Italian navy. The approximately 93 mm long blade made of Böhler N690 steel (HRC ≈ 58) features an asymmetrical spear-point and about 20 mm of partial serration, allowing it to cut through high-strength cables or fabrics without straining the cutting edge.
The handle is made of anodized Anticorodal aluminum and is ergonomically designed with a grip end extension that facilitates quick withdrawal. A glass breaker function is also integrated. Additionally, the titanium clip attachment is DLC-coated and can be mounted on both sides in three angles—for maximum carrying flexibility.
With an overall length of 231 mm, a blade thickness of 4 mm, and a weight of about 162 g, this folder shows an impressive combination of lightweight construction and sturdiness. This knife is aimed at professional users, collectors, and connoisseurs who expect not only functionality but also high-level quality.
Features:The Caimano Nero N.A. is a first-class folder designed uncompromisingly for high demands. It combines finest materials, thoughtful design, and tactical features in a perfectly shaped package. Those looking for a knife that convinces both as a high-quality everyday tool and as a collector’s item will find an excellent choice here. The combination of blade, handle, and equipment makes it a true statement in the field of tactical knives.
