An In depth look

Blade Type

The Bunka knife, a versatile and traditional Japanese kitchen tool, features a distinctive, angular tip and a wide blade. It's designed for precision tasks like slicing, dicing, and chopping. Ideal for handling vegetables, meat, and fish, the Bunka is a multifunctional knife celebrated for its utility and unique aesthetic.

Steel Type

Chromax is a high-end, powdered metallurgy semi stainless steel and one of the finest knife-making steels available in Japan. Its fine, uniform grain structure enables razor-sharp edges, all the while holding an edge for much longer than Carbon steel knives, without needing to be concerned about rust appearing.

Care Information

This knife is made from a high-carbon, semi-stainless steel and will be robust and resistant to rust. While it will not rust quickly like pure carbon, it is still best practice to not leave this knife wet for extended periods as it's stain-less, not stain-none! A light patina (colouration and seasoning of the steel) will still form over time.

Introducing

Takayuki Shibata

Originally known for selling knives, Takayuki Shibata has since evolved into one of Japan’s most respected independent knife makers, with his work now reaching chefs and collectors in over 20 countries. His journey—from passionate cook and craftsman to full-scale designer—has also led him to develop a wider range of kitchen tools, including high-performance frying pans and aprons, all designed with the same focus on function and durability.

Shibata-san’s philosophy is simple: “Art over Beauty.” Each knife is designed with purpose, built to perform flawlessly in the kitchen, and crafted to meet the daily demands of both professional chefs and home cooks. Clean, precise, and uncompromising — his blades reflect a deep respect for utility over ornamentation, and the belief that true beauty lies in performance.
