The Extrema Ratio Satre FX in S600 is a one-piece fixed blade built around an unusually hard industrial tool steel. The 3.75" Böhler S600 blade arrives with an EXP Dark stonewashed finish -- S600 is cryogenically treated to an exceptional 64 HRC, giving it outstanding wear resistance and edge retention, though its lower chromium content means it isn't fully stainless and benefits from the protective EXP Dark coating. The one-piece construction eliminates handle attachment points for added durability and a minimalist profile, in a compact 7.5" overall package. A black Kydex neck sheath is included for carry.
