Fixed blade Knife Extrema Ratio S-THIL Stone Washed 11.9cm 04.1000.0223/SW
The Extrema Ratio S-THIL Stone Washed 04.1000.0223/SW is a backup tactical knife of monolithic construction milled out of a 5 mm (0.2”) bar of BOHLER N690 steel, developed in cooperation with designer Thilo Arnd Schiller. The spear point blade is heat treated to 58 HRC for best combination of edge retention and toughness. It has a false double edge to make it very effective in thrusting and piercing and has a full length fuller that flows elegantly from the blade into the handle. The blade is milled integral to the knife for better compactness and lightness, with minimum thickness yet with a pattern that reminds of the classical Extrema Ratio knife grip. This profile creates two small guards and a comfortable thumb rest to prevent the hand from slipping towards the blade. On the pommel there is a diamond shaped skull crusher and a slot for a wrist strap or for giving the knife a paracord grip wrap. The stamped nylon sheath has been designed to be extremely flat and very narrow, to keep it as compact as possible. The tip of the sheath has a hole to allow debris or liquids to be expelled simply by blowing into it. The sheath can be used with belt clip, ULTICLIP or malice clip making it extremely versatile, while it is also possible to attach it to a M.O.L.L.E. webbing just by weaving paracord through it.

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.
