Tosa Knives 

Tosa Knives, also known as Tosa Hamono, boast a rich history dating back over 400 years. Their origins lie in the Tosa domain (present-day Kochi Prefecture) on the island of Shikoku, where skilled blacksmiths honed their craft to create not just swords, but also tools for everyday life. The traditional forging technique, called Warikomi, involves layering different steels for strength and flexibility.

While still deeply rooted in tradition, modern Tosa knives incorporate additional techniques like Damascus steel forging, creating beautiful layered patterns on the blade. They also utilize textures like Tsuchime (hammered finish) and Nashiji (pear skin finish) to enhance the knife's aesthetic and functionality. Today, Tosa knives remain highly sought after for their exceptional craftsmanship, making them coveted tools for both professional chefs and home cooks alike.
