Highest Recommendation
Don’t wait as long as I did to buy your first SUBA knife. It’s simply a joy to be in the kitchen with it. Not only is it beautiful and fits perfectly in your hand, it also glides effortlessly through food.

An absolute pleasure to use, and beautiful to look at. If there’s one thing you need in your kitchen, it’s a proper knife. Suba Knives more than delivers.

Fantastic Knives
Fantastic knives that truly live up to their promise (just remember to be careful – they don’t distinguish between animal and human flesh!). The service is top-notch, and you can tell the owner is truly passionate about his craft.

What Can You Use a Deba Knife For?

  • Filleting round fish and flatfish with precision
  • Chopping through smaller fish bones (using the heel of the blade)
  • Preparing fish for sushi or sashimi (though for slicing sashimi, a Yanagiba knife is recommended)

What is a Deba Knife Not For?
A Deba knife is not a general-purpose knife. It is not suitable for:

  • Vegetables – A Nakiri knife is better suited for that
  • Boning or slicing meat – Consider a Sujibiki, Santoku, or Gyuto knife instead

How to Care for Your Deba Knife
Many Deba knives are made from carbon steel, which is not stainless. To keep your knife in top condition:

  • Keep it dry – Wipe it immediately after washing
  • Store it properly – In its box, a drawer, or on a knife magnet (handle with care)
  • Avoid dishwashers – Hand wash with warm water and mild detergent
  • Oil it if unused for a long time – Apply camellia oil to prevent rust

A Brief History of the Deba Knife
The Deba knife is one of the most traditional Japanese knives. Along with the Yanagiba and Usuba, it forms the trio of classic single-bevel knives. Our Deba knives are handcrafted in Sakai, Kansai, where they have been produced for over 500 years, staying true to their rich heritage and craftsmanship.
