What is ZDP189?
ZDP189 is a premium stainless steel produced by Hitachi Metals, one of Japan's leading steel manufacturers. It contains 3% carbon and 20% chromium, achieving high hardness (up to 70 HRC) and excellent wear resistance, while also being resistant to rust. Particularly, in terms of hardness, which significantly affects the edge retention, ZDP189 is among the top-class steels for blades. Despite these strengths, it has drawbacks such as lower toughness, reduced corrosion resistance, and being difficult to sharpen. Utilizing these outstanding material properties, skilled craftsmen meticulously create each knife. Please enjoy the exceptional sharpness.
Hitachi Metals' strongest powder steel, ZDP-189, boasts a hardness of 67 or higher, the highest of any known steel for cutting tools. It offers the ultimate combination of hardness, toughness, wear resistance, and corrosion resistance. However, due to its extreme hardness, ZDP-189 is difficult to sharpen with regular sharpening stones and is quite expensive.
