Kai Sekimagoroku KK Yanagiba Knives
The Kai Sekimagoroku KK Yanagiba collection is designed with a singular purpose: precision slicing. Handmade in Japan, this Professional Series range reflects the traditional form of the Yanagiba, a knife developed specifically for preparing sashimi and slicing fish with accuracy and control. The design is pure and uncluttered, focusing entirely on function.
Each blade is crafted from 8A high carbon stainless steel and hardened to approximately 58 HRC, offering a balance of sharpness and durability suited to professional environments. The long, slender blade profile allows for smooth, uninterrupted slicing motions, while the single-bevel edge geometry supports wafer-thin cuts with minimal surface disruption. Finished with a black matt pakkawood handle in a traditional octagonal form, the series combines specialist performance with restrained Japanese aesthetics.

Our Personal Opinion
In person, the satin blade finish and soft wavy detail are subtle and restrained. There is no decorative excess, just a clean surface that reflects the knife’s professional intent. The octagonal pakkawood handle feels secure and controlled, particularly when guiding the blade through delicate proteins.
In use, the single-bevel edge delivers clean, uninterrupted slices when used correctly. The knife rewards a calm, steady motion and produces precise cuts with minimal tearing. As a collection, the KK Yanagiba feels focused and traditional, designed specifically for those who value technique and accuracy in fish preparation rather than general-purpose versatility.
