Masahiro Knives Masahiro MV-H knives are produced in Seki, Japan.
The edge is 80/20 asymmetrical and is polished to a mirror finish. What we mean by 80/20 asymmetrical is that 80 percent of the edge is ground on the right side of the blade and 20 percent is ground on the left side. The benefit of this type of edge is that an asymmetrical edge can be made much sharper than a 50/50 straight edge.
The MV-H is made from MBS-26 high carbon stainless steel. This MBS-26 is proprietary to Masahiro and the stainless steel is treated by three stages of quenching, sub-zero treating and tempering until the steel reaches a hardness of 58-60 HRC.
