KASUMI / Kasane

Sumikama's history begins in 1916, when the previous head, Ushimatsu Sumikama, started making pocket knives in Seki City. Through forward-thinking initiatives such as introducing punch presses, it contributed greatly to the development of today's Seki blade industry while expanding its business into home and professional blades.

In time it grew into a maker planning and manufacturing a diverse range of blades and household goods — home and professional knives, cookware, industrial blades, gift items and more. While drawing on the traditional techniques of Seki swordsmithing, it has actively taken on new materials and technologies: adopting original materials through collaboration with steel makers, and using molybdenum-vanadium steel, Damascus steel and titanium coating.

Its current flagship brands, "KASUMI" and "Kasane," are designed with emphasis not only on the practicality that supports daily cooking but also on the artistry that lifts the user's spirits. By having skilled artisans finish each knife one by one, they are crafted into kitchen knives that combine sharp, lasting cutting performance with the joy of ownership.

Sumikama's products are chosen not only by households and professional kitchens in Japan but by users in about 50 countries worldwide. Accumulating awards at international trade fairs and a track record of adoption at world cooking competitions, it continues — through making that pursues "cutting performance" and "functionality" — to contribute to a richer, more enjoyable food culture for people around the world.

Founded in 1916, a blade maker carrying on the tradition of Seki swordsmithing

Sumikama's roots lie in pocket-knife making that began in Seki City, Gifu, in 1916. Inheriting the tradition and outstanding blade-manufacturing skill of Seki swordsmithing — with over 780 years of history — it has expanded into home and professional blades and cookware, continuing to make high-quality blades and household goods.

A diverse range of knife series, including "KASUMI" and "Kasane"

It offers a rich array of series to choose from by use and style: "KASUMI Damascus," distinguished by its flowing Damascus pattern; "KASUMI Titanium Coating," achieving colorful blades through titanium coating; "Kasane," with designs that fit into daily life; and the professional-grade "KASUMI VG-10 PRO."

A global brand loved in over 50 countries

Sumikama's knives are shipped not only within Japan but to about 50 countries worldwide. Winning "DESIGN PLUS" at Germany's Frankfurt Messe and being adopted at the world's top cooking competition, the "Bocuse d'Or," it has earned international acclaim as a blade brand combining design and functionality.
