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.
