Aside from Shigefusa, the other Sanjo-based makers that we love are Hinoura and Yoshikane.
Hinoura is a well-known family of blacksmiths that have been making knives for over 120 years. It's a father-and-son team led by Mr. Tsukasa Hinoura where he started knifemaking in 1975. On the other hand, his son, Mr. Mutsumi Hinoura (the fourth generation), started making knives in 2001. Hinoura is well-known for its techniques that retain fine edges longer than any other knife on the market.
Yoshikane hamono, established in 1919, is currently led by fourth-generation blacksmith Kazuomi Yoshida. We personally love their subtle and yet stylish nashiji-finished knives.
These makers are one of the favorites among J-knife enthusiasts.
