Tsukasa Tokaji continues the blacksmithing tradition passed down from his grandfather, a legacy spanning three generations. After graduating from high school, he immediately joined the family business and has since dedicated over 40 years to knife-making. Following in his father's footsteps, he still handles every step of the process—from forging to hardening and sharpening—entirely on his own. His accumulated experience and intuition are embodied in every single knife he creates.
What Mr. Tokaji values most is "temperature control." He explains that in every stage—forging, shaping, and hardening—even the slightest temperature difference can affect the condition of the steel. In particular, the boundary between the steel and the base metal that appears when the knife is sharpened is a crucial indicator of the precision of the heat treatment. A knife with a clear, beautifully defined boundary is proof that the steel has been finished in excellent condition. Even the slightest bit of overheating can make the steel "lose its edge," so discerning the correct balance requires the experience and intuition cultivated over many years.
He strives to create knives that can be used for a long time, valuing not only sharpness but also how fully he can bring out the steel’s inherent properties. Even now, as he receives high acclaim from overseas, he remains steadfast in his stance of "never making anything sloppy," quietly preserving Kochi’s blacksmithing culture.

What Mr. Tokaji values most is “temperature control.” He explains that in every stage—forging, heating, and quenching—even the slightest temperature difference can affect the condition of the steel. In particular, the boundary between the steel and the base metal that appears when the knife is sharpened is a crucial indicator of the precision of the heat treatment. A knife with a clear, beautiful boundary is proof that the steel has been finished in excellent condition. Even the slightest over-tempering causes the steel to “lose its edge,” so discerning the right balance requires the mastery that is only earned over decades.
