Yoshimune is made by Kawamura Hamono in Sanjo, Niigata, a small family operation for over 50 years. While not as glamorous as some of the Sanjo masters like Shigefusa and Hinoura, their knives are still made traditionally involving equipped with Sanjo's most distinctive features, while with a surprisingly good price.
These days many knife enthusiasts swear by the Sanjo knives, yet because most of the Sanjo products are made by small scale, family run workshops that the craftsmen ofteh have do everything from froging to grinding, their production is severely limited. We see most more popular brands always get sold out immediately, and the price is going up day-by-day. It is definitely rare to see a true Sanjo knife offered at this sort of price.
