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
HAP40 is an extremely hard (often HRC65) powder semi-stainless steel by Hitachi Metals in Japan. It holds an edge for an extremely long time and will develop a patina with use. It has enough chromium content to ward off rust spots if left wet for short periods, but best to be kept dry after use. It can be tricky to sharpen without a coarse stone of around 500 grit to get the burr moving.
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
Hatsukokoro
Based in Amagasaki, Hatsukokoro partners closely with a wide network of skilled Japanese blacksmiths (Think Yoshikane, Myojin, Yauji and many more) and manufacturers to create an expansive range of kitchen knives. Their approach is rooted in collaboration — drawing on the strengths of various makers across Japan to develop collections that span from accessible entry-level pieces to exceptional high-performance tools.
