FAQs
No. The Zhen bunka is a 3-layer san-mai blade - a ZDP-189 core clad in two layers of SUS405 stainless. It is a composite stainless-clad construction, not a patterned Damascus blade.
The cutting core is Japanese ZDP-189 powder steel, roughly 3% carbon and 20% chromium, hardened to 65–67 HRC and clad in SUS405 stainless.
It is a Japanese all-purpose knife. The flat edge handles push cuts through vegetables and herbs, and the K-tip gives you a precise point for scoring, fine slicing and trimming boneless proteins.
65–67 HRC. That is harder than most premium kitchen knives, which sit around 60–62 HRC, so it holds a keen edge longer between sharpenings.
No. Hand wash and dry it immediately. The high-carbon core is reactive, so keep it off bone, frozen food and the dishwasher.
A classic octagonal Japanese wa-handle in North American Desert Ironwood and White Buffalo Horn, running on a hidden tang (a partial tang).
Ground to 15 degrees (±1) per side, matched to the hardness of the ZDP-189 core for a fine, precise edge.
