Extrema Ratio 25 years: S-THIL "Black Warfare" Special Edition
Extrema Ratio presents the new integral, fixed blade S-THIL knife, in a “Black Warfare” special edition
The Extrema Ratio S-THIL Black Warfare, special edition of the S-THIL model, 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, 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 latter is milled integral to the knife for better compactness and lightness, with mininum 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 any chance of the hand 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 Black Warfare special edition sports the innovative and original Geotech Camo pattern from Extrema Ratio, laser etched into the knife’s surface
The stamped nylon sheath has been designed to be extremely flat and very narrow, to keep it as compact as possible. Knife design makes the sheath ambidextrous and allows to insert the knife with the edge on the left or the right.
The integral twin retention system is composed of four pressure elements that work one pair at a time, according to the direction the knife is inserted, while the textile nylon part has a button and strap to secure the knife to the sheath. 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 couple it to a M.O.L.L.E. webbing just by weaving paracord through it.
The Extrema Ratio S-THIL Black Warfare “Special Edition” is delivered in a weather, dust and shock resistant Polypropylene IP67 certified waterproof case, with pressurization valve, which carries also the Nylon sheath, double ULTICLIP, a double grit honing plate (ceramic and synthetic diamond) and a metal plaque bearing the progressive number within the limited series.
