Hitachi’s hardest and highest performing Japanese knife steel in the knife industry. This Japanese manufactured powdered metal has phenomenal chemistry with 3% carbon and 20% chrome (unheard of chemistries twenty-years ago). As a result, ZDP-189’s hardness measures high on the Rockwell scale (65-67) and its edge retention is exceptional. At this time, Spyderco was one of a handful of cutlers around the world working with ZDP-189 blades.
