The Extrema Ratio S-THIL is a backup tactical knife with a monolithic structure milled out of a 5 mm (0.2”) bar of BOHLER N690 steel, developed together with designer Thilo Arnd Schiller.

The blade is of spear point profile, heat treated to 58 HRC for best combination of edge retention and toughness and has a false double edge for best thrusting and piercing capabilities, with a full length fuller that elegantly flows from the blade into the handle.

 

The latter is milled integral to the knife for better compactness and lightness, with minimum thickness yet still having a pattern that reminds of the classical Extrema Ration 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 knife is available in a stone washed or Dark Stone finish.

 

The stamped nylon sheath has been designed to be extremely flat and very narrow, to keep it as compact as possible.

Its design makes it ambidextrous and allows to insert the knife with the edge on the left or the right.

 

The Extrema Ratio S-THIL is provided with the nylon sheath and a length of paracord.

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.
