At the tender age of 16, Minosuke Matsuzawa left his hometown of Tokyo for Sakai to study knife crafting. Sakai was then considered the natural place for a young knife craftsman to go to study his art. During his apprenticeship, Matsuzawa identified the features in Inari clay that made it the ideal material for use during the tempering process in knife forging. He found that a similar type of clay could also be found in Kanto. He was so excited by this discovery that he deserted his craft master in the middle of training and rushed back to Tokyo. Matsuzawa founded Masamoto Sohonten Company and started making knives in 1866. It was his dream that his family would come to be remembered as knife craftsmen throughout the generations. Now, five generations later, Matsuzawa’s vision has been realized and professionally crafted Masamoto knives have become widely regarded as the finest knives made for professional use.
