Carbinox T508 steel combines the best properties of carbon and chromium steel: toughness, ease of sharpening and extreme durability. The carbon content of the steel mixture is 0.5%, chromium content 8% and it has a hardness of 56–57 HRC. The material is not classified as stainless, although it significantly more corrosion resistant than traditional carbon steel. The basic maintenance of a Carbinox T508 blade requires nothing more than cleaning and drying the blade after use. We do, however, recommend oiling the blade with unsalted oil every now and then.
