Frequently Asked Questions

What is a Deba knife used for?

The Deba knife is a traditional Japanese kitchen knife specifically designed for preparing fish and seafood. It is used to clean fish, separate fillets from bones, and cut them into pieces of various sizes. The thickened, wedge-shaped blade can withstand greater stress compared to ordinary kitchen knives.

What type of steel is used for the blade of the FC-572?

The blade of the Fuji Cutlery FC-572 is made of Mo-V stainless steel. This steel provides good corrosion resistance and edge retention. Its hardness is 57–58 HRC, which is suitable for everyday kitchen use.

What does "single-sided sharpening" mean in the context of Japanese knives?

Single-sided sharpening means that the cutting edge is shaped on only one side of the blade—in this case, the right side. This is a traditional Japanese technique that ensures an exceptionally precise cut. Such knives are designed primarily for right-handed users and require a specific sharpening technique for maintenance.

What is the handle of the FC-572 knife made of?

The handle is made of magnolia—a traditional material used in Japanese kitchen knives. Magnolia wood is lightweight, pleasant to the touch, and provides a secure grip while working. This material has been used for centuries in Japanese knife-making because of its practical qualities.

Is the FC-572 knife dishwasher-safe?

No—the knife should not be washed in the dishwasher. Harsh detergents and high temperatures can damage both the blade and the magnolia handle. It is recommended to wash the knife by hand with warm water and dry it immediately after use.

How do I keep a Japanese Deba knife sharp?

Regular sharpening is key—it’s easier to maintain a knife that’s already sharp than to sharpen one that’s severely dull. Use a suitable sharpening stone that’s appropriate for the single-sided bevel of the blade. Avoid cutting on hard surfaces such as glass, porcelain, or bamboo, as these quickly dull the cutting edge.

Is the FC-572 suitable for home use, or is it only for professionals?

This knife is suitable for both home and professional use. Anyone who regularly prepares fish and seafood at home will appreciate its convenience and precision.
