The Extrema Ratio Satre is a pocket-sized, lightweight and extremely tough fixed blade knife. Given its characteristics, it can be employed in a large variety of activities and fields such as survival and bushcraft. It was designed in collaboration with Daniele Dal Canto, a Master Advanced F.I.S.S.S. instructor (Italian Federation of Sport and Experimental Survival).
The Satre can be worn as a neck knife thanks to its Paracord 550 lanyard. This way, it is possible to keep it vertical with the handle facing down. The pre-shaped Kydex sheath has eyelets, allowing to apply both lanyard and accessory holder.
Satre is available in three versions with two different kinds of steel: This black coated version is made with heat-treated Böhler N690 steel at 58 HRC. This material was chosen for its resistance to oxidation, for the durability of its edge and especially for its reliability, which has been proven over the years.
The steel has excellent qualities in terms of hardness, wear resistance and toughness thanks to the presence of molybdenum, tungsten and a significant element of vanadium to its chemical composition.The presence of cobalt stimulates the growth of small uniformly-distributed carbides, which enhance wear resistance.
