Use a sharpener experienced with Japanese convex edges
よくあるご質問
Does the matte black coating affect cutting performance?
No. The frost matte black coating is a surface treatment that does not alter the blade's VG-10 steel properties or convex edge geometry. It reduces glare and adds a visual distinction but has no effect on sharpness or edge retention.
Is the matte black coating durable?
Coatings do wear over time with daily use, particularly at contact points. This is cosmetic and does not affect cutting performance. The underlying VG-10 steel is fully protected regardless of coating condition.
