Some of our reviews

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 👊🏽

Nigara Hamono SG2 Raindrop Damascus Bunka 180mm - Ebony

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!

Beautiful Knife

As the title says, an absolutely beautiful knife. Even better than the photos. Shipping was also reasonable. Very happy, would definitely recommend.

Matsubara Hamono Blue 2 Tsuchime Bunka 180mm

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.

Perfect knife!

It was absolutely razor sharp knife. Lightweight even if it’s 240mm knife. Thanks chef’s edge, it came also fast and secured with a beautiful delivery box.
