This "thin series" wa-petty knife is a "laser" knife, hand-forged, handcrafted and hand-sharpened by a team of traditional artisans and craftsmen. With Ginsan (Silver #3) steel, you get similar hardness and some of the characteristics of Shirogami #2, but with stainless / rust resistance properties, making this knife much easier to maintain. The grind is quite smooth, with good thinness behind-the-edge and quality sharpening matching the price range of this series. The polish is done to a higher standard than most other knives of this cost, so the knife is very enjoyable to use. More importantly, Kaishin's magnolia handle comes with a blonde/marble buffalo horn kuchiwa, something less seen in knives of this budget range. Overall this is a knife of superb value for money.

About Kaishin 魁心 / Nakamura Hamono Kogei 中村刃物工芸
Nakamura Hamono Kogei is a young company founded in 2015 as a teamworking workshop for emerging traditional Japanese blacksmiths.

Ginsan (Gin3 or Silver #3) is a stainless carbon steel, with 14% added Chromium. Retaining the character of Japanese carbon steel, with similar hardness of Shirogami #2, Ginsan is stainless. It's edge retention is only slightly inferior to Shirogami #2, but the fact that it combines ease of sharpening, carbon steel character as well being stainless makes it a great choice for those who wish to have a Japanese carbon steel knife that is easy to maintain.
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.
