博多包丁 刃渡り18cm 大庭鍛冶工場 新品、未使用です。 In Kiyokawa, Fukuoka City, 80+ year-old blacksmith Toshio Ohba is the last maker of Hakata knives, forging them for over 65 years. Recognized as a “Master Craftsman” by Japan’s Ministry of Health, Labor and Welfare, he hails from a three-generation blacksmith lineage. His Hakata Bocho features a triangular tip, a slight spine curve, and a kurouchi finish that preserves forge char for rust protection. Ohba also crafts and repairs traditional rakes for sumo arenas, pausing knife orders when rakes arrive each season. He has one apprentice, Haruo Miyazaki, whose training began at Yoshimitsu workshop before joining Ohba. Custom Hakata knives can take up to six months, including sujihiki slicing knives.
