Folding knife Extrema Ratio Caimano Nero 9.3cm 0410000169BLK
The Caimano Nero is a tactical knife delivered to the G.O.I., Gruppo Operativo Incursori (Operational Raiders Group) of the Italian Navy, and designed by Extrema Ratio, official COMSUBIN supplier. Its name is a reference and a tribute to the heroic Caimani Neri del Piave (Black Caimans of the Piave river), a unit of the Arditi della Regia Marina (Italian Royal Navy), who used to swim across the Piave river to carry out raids on enemy territory during the First World War. It is an automatic knife with a 4 mm asymmetrical spearpoint blade and a partial sharp false edge to improve the coefficient of penetration. The serrated part of the edge allow to cut highly-resistent cables and fabrics without losing its sharpening. It is a medium folder with a robust structure. It is light and balanced thanks to numerous removal processes applied to its highly-thick aluminum handle scales. The pommel, which recalls the shape of the tail/propel section of the Siluro a lenta corsa (S.L.C.), is designed to improve a rapid extraction of the knife from the pocket. The DLC-coated titanium clip can be positioned in three different angles on both sides to allow maximum customization while wearing it. Its shape is designed to conceal the handle sticking out of the pocket. The automatic blade release system guarantees a complete opening even in the event of accidental impacts during the opening rotation. Among its features, it is equipped with an hard-metal glass breaker and a lock, which prevents the blade from dangerously closing by accident.

Folding knife Extrema Ratio T-Razor Satin 10cm 04.1000.0138/SAT
Extrema Ratio T-Razor folder with satin blade. Up to the early 1900s, people commonly carried pocket utility knives. Due to rampant “misuse”, though, laws were passed to the effect that all such knives were to be clipped at the blade-tip, in order to diminish their dangerousness as weapons. Some people then figured they’d get the greatest effectiveness out of the sharp edge of a traditionally flat-point blade shape, and took to carrying straight-razors. Thus, the straight-razor was for a time regarded as a fearsome weapon of self-defense. Such a “misuse” of the common straight-razor inspired our T-RAZOR design. Available versions: T-RAZOR BLACK, T-RAZOR SATIN.
