Ishikawa-san is the owner and blacksmith of Nakaniida Traditional Blades. He is the only remaining blacksmith in Kami-machi in Miyagi Prefecture and makes all of his Japan knives one hundred percent by hand.
His methods of steelworking are indeed unique: Ishikawa-san hammers the already cooled steel, giving his blades great flexibility while maintaining extreme sharpness. He puts all his focus on the performance of his knives, not on their appearance. You can immediately feel the quality of his work when you hold his masterpieces in your hands.
A Japanese knife from Ishikawa-san is one of the last available knives made in the Nakaniida forging style.
