Extreme Ratio S-THIL BLACK WARFARE
Product Description
The Extrema Ratio S-THIL Black Warfare, a special edition of the S-THIL model, is a tactical backup knife with a monolithic construction milled from a 5 mm (0.2″) bar of BOHLER N690 steel, developed in cooperation with designer Thilo Arnd Schiller. The spearhead blade is heat-treated to 58 HRC for the best combination of edge retention and strength. It has a false double edge to make it very effective at piercing and penetrating, and has a full-length fuller that flows elegantly from the blade to the handle.
The blade is integrally milled into the knife for better compactness and lightness, with minimal thickness but with a pattern reminiscent of the classic handle of the Extrema Ratio knife. 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 notch for a wrist bracelet or to give the knife a paracord grip wrap. The Black Warfare special edition features Extrema Ratio’s innovative and original Geotech Camo pattern, laser-engraved on the surface of the knife.
The printed nylon sheath is designed to be extremely flat and very narrow, to keep it as compact as possible. The design of the knife makes the sheath ambidextrous and allows the knife to be inserted with the edge to the left or right. The integral double retention system is made up of four pressure elements that work in pairs according to the direction in which the knife is inserted, while the nylon textile part has a button and a strap to secure the knife to the sheath. The tip of the sheath has a hole in it to allow debris or liquids to be expelled simply by blowing into it.
The sheath can be used with a 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. web by simply weaving paracord through it.
The Extreme Ratio S-THIL Black Warfare ‘Special Edition‘ is delivered in a weatherproof, dustproof and shockproof IP67-certified polypropylene case with pressurizing valve, which also carries the nylon sheath, double ULTICLIP, double sharpening plate (ceramic and synthetic diamond).
