Product Overview

The TSUBAME SANJO KAJIBE Santoku Aogami 165mm is a professional-grade Japanese all-purpose knife, hand-forged in the historic blacksmithing town of Tsubame-Sanjo, Niigata—a region renowned for centuries of metalworking excellence.

Known as the “town of blacksmiths,” Tsubame-Sanjo has produced fine blades for centuries, with craftsman culture rooted in Edo-period forging traditions.

Kunio Ishikawa – Master Craftsman

Kunio Ishikawa is a third-generation blacksmith who has dedicated more than forty years to his craft.
As a smith forging blades through changing times, he has continued to hammer steel with unwavering commitment.

While the workshop once focused primarily on forged blades that sold as soon as they were made, Ishikawa now concentrates on crafting kitchen knives.
For many years he specialized in magiri—razor-sharp knives used by fishermen for processing fish at sea. However, as deep-sea fishing declined and demand for such tools diminished, Ishikawa shifted his craftsmanship toward nakiri knives, refining tools suited for the modern kitchen while preserving the traditions passed down from previous generations.

Today, he remains dedicated to creating knives that embody both heritage and innovation, one hammer stroke at a time.

Forged and sharpened one by one by skilled craftsmen, this knife embodies the spirit of traditional Japanese blacksmithing.

“Santoku,” meaning “three virtues,” refers to its versatility in handling meat, vegetables, and small fish, making it an indispensable blade for both home cooks and professionals.

The blade is crafted from Yasugi Aogami (Blue Paper Steel) laminated with soft iron.
Aogami steel is known for its exceptional sharpness, outstanding edge retention, and excellent sharpening response.
The layered construction produces subtle, wave-like patterns on the blade surface, reflecting the hand-forged nature of each knife.

Finished with a durable chestnut wood handle, the knife offers a secure, comfortable grip and a warm, natural aesthetic.
This is a true craftsman’s santoku—built for performance, longevity, and everyday use.
