About cutler SANSYU seki japan


The finest knives forged by the master craftsmen of SEKI, Japan's most historic blacksmithing ctiy.

Handcrafted by the master blacksmiths of Seki, Japan, Sanshu knives are the product of 800 years of forging traditions. Seki is the country's most historic blacksmithing city, the place where Japan's legendary samurai swords were conceived. Today, the same techniques used to create those hallowed blades are now used to create the finest kitchen knives in Japan. And today, too, the essential characteristics that defined samurai swords―sharpness, precision and durability―remain the hallmarks of Seki's Sanshu kitchen knives.
Run by the third-generation owner, Sanshu creates their fine knives the age-old Seki way, by commissioning a core group of local blacksmiths to forge them. These talented artisans undergo arduous apprenticeships to master their craft; while some 300 of them worked in Seki during the heyday of sword forging in the 1500s, only eighteen remain today. The blacksmiths provide
Sanshu with finished blades; the company's own craftsmen then fit custom handles and hand-hone a final edge. Only then are Sanshu knives ready for duty in the kitchen.


Sanshu knives are produced from the highest quality Japanese and imported steels. They're durable, incredibly sharp and retain their edge longer than other kitchen knives. They're a joy to cut with and will last for years and years. Prized by top professional chefs across Japan, Sanshu knives are now being introduced to the United States for the first time.

Seki-city of Japan,関市


Seki-city of Japan is highly regarded as "the world's third largest cutlery producing area" along with Solingen in Germany and Sheffield in England. Its skill and quality supported by history and tradition are appreciated not only in Japan but also overseas. Seki-city, which has grown to become a world brand, has three important conditions for producing of cutlery. The first one is an abundant water source of the Nagara river. The second one is the coal for quenching. And the third is the red clay painted when making a blade. Even today as the industry has been modernized, the rich natural environment of water, mountains and soil supports the cutting tool industry.
