Tetsujin

Tetsujin represents a unique collaboration in Japanese knife-making, bringing together the complementary skills of blacksmith Toru Tamura and master sharpener Naohito Myojin. This partnership combines traditional forging techniques with expert edge geometry, resulting in kitchen knives that excel in both performance and aesthetics. The brand name "Tetsujin" translates to "master of iron," reflecting their dedication to the craft of blade-making.

The brand specializes in Japanese kitchen knives crafted from premium high-carbon steels, particularly Blue #2 (Aogami) steel and Ginsan (Silver Steel). These materials are heat-treated to achieve an impressive hardness of 63+ HRC, delivering exceptional edge retention while maintaining the necessary toughness for daily kitchen use. This careful balance of hardness and durability makes Tetsujin knives particularly appealing to both professional chefs and serious home cooks who demand reliable cutting performance.

Tetsujin's product line focuses on essential Japanese knife styles including Gyuto, Kiritsuke, and Bunka designs. What distinguishes these knives is their attention to aesthetic detail alongside functional excellence. The brand is known for signature finishes like Kasumi, which features a polished core, and Ukiba, characterized by distinctive scratch patterns. These traditional finishing techniques not only enhance the visual appeal but also contribute to the blade's food-release properties.

The collaboration model that defines Tetsujin ensures each knife benefits from specialized expertise at every stage of production. Tamura's forging creates the foundation with proper steel composition and geometry, while Myojin's sharpening expertise produces edges capable of precision cutting. This division of labor, where each artisan focuses on their particular strength, exemplifies the Japanese approach to craftsmanship. Tetsujin knives are available through specialty retailers that appreciate fine Japanese cutlery, making them accessible to discerning knife enthusiasts worldwide.
