Richmond ZDP189

Here is our new line of Richmond knives featuring ZDP189 steel. These are made by a very small blacksmith shop in Sanjo City called Gihei and the blades are gorgeous with a high level of fit and finish. ZDP-189 Made up of Carbon: 3.00%, Tungsten: 1.50%, Vanadium: .10%, Chromium: 20.00%, Molybdenum: 1.30%. This is one of the most recent developments in PM steels. It is extremely high in Carbon and Chromium making it very expensive to manufacture. It is known for its amazing wear resistance and capability to be hardened to 67 HRC. Regarding the matter of hardness, Gihei tells me the target is about HRC64-65. We backed it off from maximum hardness to give the blades a little more toughness.
