Kei Kobayashi—The Second-Generation Master of Seki’s “Sharpening” Art
Born and raised in Seki City, Gifu Prefecture—the “City of Knives”—Kei Kobayashi (born in 1977) is a sharpening specialist who originally worked on the edge preparation and finishing for Seki’s master craftsmen. Building on the sharpening techniques he honed over many years, he took over the family business and launched his own brand, “Kobayashi Knives,” which has since garnered attention from chefs and collectors around the world. By limiting his blade material to SG2 (R2) powdered high-speed steel, and featuring a thin, sharp “laser-like” edge and an instantly recognizable heptagonal red-handled design, he has infused traditional Seki cutlery with a new sense of individuality.

Three Reasons Why Chefs and Collectors Worldwide Seek Out Kei Kobayashi’s Knives
1. “Sharpness” Unique to a Master Sharpener—Sharpening Techniques That Supported Seki’s Master Craftsmen
Kei Kobayashi is a sharpening expert who has honed the blades of numerous master craftsmen in Seki City. He pours the proprietary sharpening techniques he has refined through this experience into his own knife-making. With “superb sharpness” as his primary goal in knife-making, his knives outshine the competition with their immediate penetration and smooth glide the moment the blade makes contact.
2. The One-of-a-Kind “Heptagonal Red Handle”—The Kobayashi Mark Recognizable at a Glance
The uniquely developed heptagonal red handle combines ease of grip with ease of cutting, while also serving as an instantly recognizable identifier—even among a row of knives—that it is a “Kei Kobayashi” creation. The limited-edition series featuring lacquered handles includes knives of art-quality craftsmanship adorned with traditional Japanese designs.
3. Seki Tradition SG2 Powdered High-Speed Steel—Today’s Finest Stainless Steel
While carrying on the traditions of Seki, the “City of Knives,” the blade material is limited exclusively to SG2 (R2) powdered high-speed steel. It features a three-layer (sandwich) structure in which the core material is heat-treated to a hardness of approximately 63 HRC and sandwiched between softer stainless steel layers.
This makes the blade rust-resistant and easy to maintain; even when sharpened to a thin edge, it retains its edge well, ensuring long-lasting sharpness. The combination of traditional sharpening techniques and modern materials results in a level of craftsmanship that stands up in both professional kitchens and private collections.
