Seki Kanetsugu "Zuiun" R2/SG2 Damascus 210mm Kiritsuke Gyuto

by Seki Kanetsugu


Created to celebrate the 100th anniversary of Seki Kanetsugu, the “Zuiun” series knives are made with R2/SG2 high-speed powder core steel, heat-treated and cold-treated to 62-63 HRC, enabling superb edge retention. This is the highest level of fit and finishes by Kanetsugu, with a beautiful Damascus cladding that is almost mirror-like. With a beautiful tapering, the knife has an excellent edge geometry. Supported by the harder SG2 steel, the knife maker was able to achieve excellent thinness behind the edge, facilitating great cutting performance. This knife features a special Shichikaku (Heptagon) handle made of brown pakkawood, with a beautiful mosaic pin for decoration. The "Zuiun" offers one of the best overall fit and finishes at this price range. All knives in this series come in a lovely Paulownia wood box.

About Seki Kanetsugu 関兼次

Seki Kanetsugu was founded more than a century ago in 1918 by Matsujiro Kawamura, the descendant of Kanetsugu the swordsmith, who first started making swords in the year 1345. For three generations, the Kawamuras have worked hard to build a knife workshop that is worthy of the Kanetsugu name. Combining Seki's knife making tradition and newer approaches such as "sub-zero process", Seki Kanatsugu has become a major knife maker in Japan. In 2018, Kanetsugu celebrated their centenary by launching the brand new “Zuiun” (瑞雲) series, with the finest Damascus steel that recreates the good omen Buddhism symbol of clouds.


Wash and dry with a soft sponge, and safely store after use. Avoid cutting into bones, frozen foods, hard fruit pits.

Cutting Surface:

Recommended cutting surface: wood, rubberized boards and high-end composites, and quality plastics such as polyethene make acceptable cutting surfaces, and will help protect and prolong knife’s edge. AVOID glass, metal, countertops, and other rigid, non-forgiving surfaces.


We recommend sharpening all quality Japanese knives on whetstones, as we believe they yield the best results for your knives.
