- Chef’s Note on Maintenance: Due to the extreme 67 HRC, we recommend maintenance strictly with high-quality whetstones or ceramic rods. This steel is exceptionally tough and will not chip under normal professional use on wood or synthetic boards, but it should never be used on bone or frozen items.
When We Recommend the Miyabi Black Series
Who it Fits Best
This tool is for the 'prep powerhouse'—the professional chef who spends 4-6 hours a day on a cutting board and demands a tool that doesn't require constant mid-shift honing.
Where it Excels
It is unbeatable for precise vegetable work, including paper-thin radish slicing and dense mirepoix prep, where the flat profile maximizes efficiency.
Professional Comparisons
It is significantly harder than a Wusthof (58 HRC) or even a Shun Classic (61 HRC), offering nearly triple the edge life at the cost of requiring more specialized sharpening skills.
Chef Feedback
"Line cooks love the 'Black Ash' handle because it provides more grip when hands are slightly damp compared to the smoother Birchwood or metal Global handles."
Trade-offs & Considerations
The 67 HRC core is a thoroughbred; it requires a chef with good technique. If you are prone to twisting the blade on the board or hacking through fish bones, you will eventually find the limit of its toughness.
