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.

This thing IS THE BUSINESS!

Words can't explain how amazing this knife is to use and gaze at! It's my second bunka and my go to knife for everyday prep. Gyuto's aren't getting a look in at the moment. I LOVE it. Thanks Chefs Edge 👊🏽

Super Thin Bevels

The bevels being so thin makes it easy to achieve a crazy sharp edge and cut dense vegetables rather than splitting them. The kiritsuke tip also makes precise cuts such as on garlic possible. A pleasure to use

Great product, great service

Very happy with my purchase. First time customer, ordered and received a knife that had a chip which occurred during shipment. The staff at Chefs Edge were very prompt in communication and really helpful in resolving the matter. They sent out a new knife and arrived in time for a birthday. The knife itself is great quality and looks better than the photos. Overall, very happy and will be a return customer!

Fantastic knife with beautifully curated handle

Got this as a gift for one of my younger cooks who has been going above and beyond this year. Not only is the caretaking aspect of high carbon steels such as shirogami a great teacher for any future knives they may own, but its such a beautiful tsuchime finish with a fantastic grind that I found myself drooling over it aswell. 10/10 recommend not only Tsunehisa as a maker but Chefs Edge as a curator and purveyor of immaculate kitchen knives.
