Since 1560, Aritsugu has preserved the legacy of Japanese sword-making, maintaining its position as one of Japan’s most prestigious knife makers to this day.
Historically, their blades were so renowned for their exceptional sharpness that they were dedicated to the Japanese Emperor.

When chefs use Aritsugu, they can cut ingredients in a way that truly brings out their natural flavors, inspiring greater creativity and expanding their culinary vision.
This is why world-class chefs have cherished Aritsugu for centuries.
