We’re proud to announce the release of the newly introduced Konosuke BY 225mm Gyuto in Blue #1 Steel, the latest creation from our friends at Konosuke Sakai.
This new line is forged by the legendary Yoshikazu Tanaka, one of Japan’s most respected blacksmiths, and finished entirely in-house at Konosuke’s workshop. Each blade is hand-sharpened and polished on Japanese whetstones by Konosuke’s own craftsmen, ensuring the flawless grind, polish, and fit and finish that the brand is known for. The result is a knife that embodies the perfect balance of tradition, performance, and refinement.
