As pure and refined as traditional Katana steels

“Tama-Hagane”, meaning a special kind of precious steel in Japanese, also known as the material for Katana swords, is only produced in very limited quantities through Western Japan’s traditional "Tatara Steelmaking" process. With its high purity and superb uniformity, Tama-hagane has consistently been used to enable the capabilities of Katana swords. Today, the original steel making techniques have evolved into present Japanese specialty steel production. These materials based on ancient technologies are not only used to make knives and blades, but are also used to meet the world’s modern demands from the electronics, automobile, energy, and other advanced fields.

Commitment to Blades
Finely sharpened with high precision and toughness

As part of Katana crafting, advanced polishing technologies were developed to achieve a perfect balance between function as a sword and beauty as an artwork. The quality of polishing is said to determine the value of Japanese swords, and apart from swordsmiths, there also existed specialized "sharpeners" who were entirely dedicated to the polishing process throughout their lives. Similarly, our experienced blade specialists engage in realizing exquisite sharpening finishes day after day, developing original techniques passed down from our predecessor craftsmen of the past.

Advanced ceramic technology reinforces quality and durability

Since their introduction to Japan in the form of pottery more than 2,000 years ago, ceramics have undergone numerous transformations, ultimately evolving into today's advanced-ceramics for industrial needs. In addition to their natural heat-resistance and insulation properties, modern science and technology have developed the functionality of ceramics to an advanced levels. Likewise, we were able to design a ceramic coating with fine-grain, uniform particles to enable a high level of durability that can endure the harsh conditions experienced during printing and coating processes.
