The blade of the DOBERMANN IV S600, made from Böhler S600 steel, offers excellent hardness, wear resistance, and toughness, thanks to the high content of molybdenum, tungsten, and vanadium. The addition of cobalt promotes the formation of small carbides, further improving wear resistance. With a hardness of 64 HRC, it ensures long-lasting edge retention. The “EXP DARK” teflon coating protects the steel from oxidation.
DOBERMANN IV S600 features a green forprene handle with a glass-breaking tang. It comes with a green cordura thigh sheath, adaptable for both left and right-handed users and compatible with the M.O.L.L.E system.
