FAQs

How are funayuki knives made?

The best funayuki knives are handmade in Japan with great care and precision. The blades are made of high-quality stainless steel, which is hand-sharpened to a razor’s edge.

Most funayuki knives are made of VG-10 stainless steel, which is a high-carbon steel that is known for its excellent edge retention and sharpness.

Aogami steel is another popular material for this sharp knife.

The blades are also full-tang, meaning that the metal goes all the way through the handle, making them incredibly strong and durable.

This makes the knives beautiful to look at, as well as great for use.

Funayuki vs Gyuto

What is the difference between a funayuki and gyuto knife? The answer to this question can be a little confusing because there is no one definitive answer.

In general, however, you can say that a funayuki is a type of Japanese chef’s knife that is designed for slicing seafood. It has a thinner blade than a gyuto, and it curves towards the tip, which makes it easier to slice through fish.

A gyuto, on the other hand, is a general-purpose knife that can be used for slicing meat, fish, and vegetables. It has a thicker blade than a funayuki and a more curved shape, which makes it better suited for chopping than slicing.

So, which one should you choose?

If you’re mainly going to be using your knife for slicing seafood, then a funayuki is the better option.

If you’ll be using your knife for a variety of tasks, not just slicing seafood, then a gyuto is a better choice. Ultimately, it comes down to personal preference

Funayuki vs Deba

What is the difference between a funayuki and deba knife?

They both look very similar since their blade width is almost the same.

The main difference between the two knives is that a deba is specifically designed for cutting fish, while a funayuki can be used for slicing both fish and meat.

The shape of the blade is another difference. The deba has a straight blade with a thick spine, which makes it perfect for cutting through fish bones. The funayuki has a curved blade which makes it easier to slice meat and fish.

However, it should be noted that these days, most funayuki and deba knives look almost identical.
