D2 and NIOLOX
D2 steel, used primarily in high-end knives, is very wear resistant and blades made from it have a very aggressive cut.
Niolox is said to have similar wear resistance to D2 steel, but with improved blade strength. Niolox blades are easily sharpened to razor sharpness.
A distinctive feature of Niolox is its 0.7% niobium content, which improves the combination of user properties-high corrosion resistance, high toughness, and high wear resistance.
Although Niolox is not a powder steel, it has a very homogeneous structure, which guarantees the quality and stable expression of the steel properties in use.
