We get questions all the time from our customers about which blade steel is best or how different finishes and coatings will affect the blade as it's used, so we've included information on the blade steels used in EnZo's knives.

BLADE STEELS


O1 Tool Steel: a low alloy cold work tool steel that must be oil-quenched in heat treatment. O1 contains small amounts of manganese, tungsten, and chromium, giving O1 adequate toughness for normal tool & die uses. O1 has deep hardening properties with fine grain structure with unusual toughness. O1 has good response to heat treatment with small dimensional changes. 

D2 Tool Steel: a high carbon, high chromium air-hardening tool steel, heat treatable to 60-62 Rc. D2 offers excellent wear and abrasion resistance, due to large volumes of carbides in the microstructure. D2 is widely used in long production cold work applications requiring very high wear resistance and high compression strength. It is machinable in the annealed condition, and, like other air hardening tool steels, exhibits minimal distortion in heat treat.

12C27 Steel: a well-rounded knife steel with excellent edge performance allowing razor sharpness, high hardness, exceptional toughness and good corrosion resistance. 12C27 is a great knife steel for hand-held knives, high-end ice skate blades and ice drills. With a hardness range of 54-61 HRC, high toughness, and good corrosion resistance, 12C27 is the recommended grade for hunting knives, pocket knives, camping knives, high-end chef's knives and tactical knives.

N690Co Steel: a Cobalt-enriched stainless steel which shares some similarities with it's other Cobalt-steel bretheren such as ATS-55and VG-10, which are used by Spyderco. The added Cobalt improves the wear resistance and edge retention of the steel in addition to ensuring a uniform grain structure.
