Extrema Ratio Satre S600 – fixed blade knife in pocket format
The Satre is a lightweight and extremely robust fixed blade knife in pocket format. Thanks to its characteristics, it can be used in a wide range of activities and fields, including survival and bushcraft, or it can be part of an EDC (Every Day Carry) kit. It was developed in cooperation with Daniele Dal Canto, a Master Advanced F.I.S.S.S. Instructor (Italian Federation of Sport and Experimental Survival).
Thanks to its Paracord 550 lanyard, it can also be worn as a neck knife. This makes it possible to hold it vertically with the handle pointing down. The pre-formed Kydex sheath has eyelets to which both the lanyard and an accessory mount can be attached.
The Satre is available in three versions with two different types of steel: the Black and Stone Washed versions are made of heat-treated Böhler N690 steel at 58 HRC. This material was chosen for its resistance to oxidation, the durability of the edge and above all its reliability, which has proven itself over many years. The Black S600, on the other hand, is made of Böhler S600 steel.
This steel is used to manufacture tools for metalworking and die making. Thanks to its chemical composition with molybdenum, tungsten and a high proportion of vanadium, it has excellent properties in terms of hardness, wear resistance and toughness. The presence of cobalt promotes the growth of small, evenly distributed carbides, which increase wear resistance. The Satre S600 is thermally and cryogenically treated to achieve an exceptional hardness of 64 HRC. This also makes it very wear-resistant and gives the edge lasting sharpness.
Böhler S600 has a chromium content of 4.5 %, which makes it prone to oxidation. For this reason, Extrema Ratio has chosen the new EXP DARK coating. Because of its extreme hardness and wear resistance, this steel is not easy to sharpen.
