Mioroshi Deba Vs Gyuto: What’s The Difference?

By Ryan Leavitt •  Updated: 07/21/21 •  6 min read

Japanese knives are traditionally task-specific. It was only after the country opened up its harbors to the rest of the world that more versatile tools were made.

The Gyuto is a better option because this is more multi-purpose. Like the Chef’s knife that it was patterned after, this does not require a whole lot of expertise to wield. Alternatively, Mioroshi Deba is for filleting and slicing fish into thin sashimi pieces. It also takes quite a bit of skill to use because of its shape and thinness.

Here are some great examples of that single-serving blade and a more modern one:

What Is A Deba?

Before we get into the details of the Mioroshi Deba, it’s important knowing that this is actually a variation on the traditional Japanese Deba.

The deba is a knife that is specifically designed for slicing, filleting and cutting fish.

For a time in history, eating four-legged animals was illegal in Japan, so the diet of an average Japanese person at the time was composed of fish and rice.

Because of this, they needed to create a blade designed to handle the delicate protein.

This is how the Deba came to be, and it is now known as one of the most useful Japanese blades you can have in your kitchen.

A Deba has a blade between 5 to 7 inches in length with a flat and razor-sharp edge.

The shape of the blade means that you have to use a push and pull motion when slicing, which is a great way to achieve precise and consistent cuts.

What Is A Mioroshi Deba?

Now that you have a rough idea of what a Deba is, then it’s time to take a look at the Mioroshi Deba.

As we mentioned earlier, this blade is a variation on the standard Deba and is designed to be a combination of a Deba and Yanagiba knife.

A Yanagiba is a blade made for slicing through boneless fish fillets like sushi and sashimi.

It has a tough and sharp blade, allowing you to slice through ingredients with a minimum amount of cell damage.

It can be used for filleting fish, but since it is made with a harder and sharper edge, it is ideal for slicing fish fillets.

Since it is very sharp and hard, this is not a recommended choice for beginners.

It requires a lot of skill and precision to use properly, but once you get used to it, this knife will instantly become a kitchen favorite!

What Is A Gyuto?

The Gyuto is one of the most useful Japanese blades out there.

This is a multi-purpose knife and is actually a Japanese take on the classic Western chef knife.

In fact, the Gyuto was specifically created to be used just like a Western chef knife and was made in response to the high demand for Western-style chef knives.

When compared to a standard Western cook’s knife, the Gyuto shares a lot of characteristics.

They will both have a relatively long blade between 8-10 inches and be one of the heftier knives in the kitchen.

The Gyuto is unique from other Japanese cutlery because it has a slightly curved edge, similar to a French-style chef knife.

So, if you’re looking for an all-around kitchen blade but still want to experience the superior sharpness of Japanese knives, then a Gyuto would be a great fit.

Mioroshi Deba Vs. Gyuto – What’s The Difference?


As mentioned earlier, the Gyuto was intentionally made to resemble a chef’s knife.

Most cooks classify it as a type of chef’s knife, so it shares a very similar design.

Since it’s made to handle a wide variety of tasks, it has a slightly curved blade that measures about 8-10 inches in length.

The edge is made to be very sharp and cut through just about any ingredients you throw at it, except bones.

On the other hand, a Mioroshi Deba is a truly traditional Japanese blade.

It features a very straight edge, designed for push and pull motions instead of rocking-chop ones.

Compared to a standard Deba, a Mioroshi Deba has a much thinner and harder blade.

This allows it to glide through fish and give you clean and precise cuts without causing cell damage.

However, since it is hard, this is also a very brittle blade that requires a lot of skill to use.


Depending on the brand and model that you’re buying, construction techniques will vary.

However, most Japanese blades are made with high-carbon steel, which gives them a tough and sharp edge.

Traditionally, Japanese kitchen cutlery will be forged from a single piece of steel.

This provides for a more sturdy and durable blade.

It isn’t uncommon, though, to find some knives with Damascus constructions.

This technique involves hammering thin layers of steel over hardcore to produce a very durable blade with a unique finish.

A Mioroshi Deba is honed to a very sharp angle of around 9-13 degrees.

Typically, these blades have a chisel-ground edge, meaning that they will only be sharpened on one side.

A Gyuto is usually double-beveled and has an edge of around 13-15 degrees on either side, which is much sharper than most Western chef knives.


A Mioroshi Deba is a very task-specific tool.

It is made specifically for filleting fish and slicing boneless fillets of fish for sashimi and sushi,

This blade can be pretty tricky to use because of its brittle construction and sharp edge, so it’s not recommended for beginners.

A Gyuto is made to handle any kitchen cutting task you throw at it.

The construction allows you to use a Gyuto for slicing meat, vegetables, herbs, and even fruits.

It is a great all-around knife for any kitchen.

A Gyuto is usually used as a chef knife substitute, and if you prefer the feel of Japanese blades, it could be just the right tool for you.


Both of these knives are very different from each other.

One is made to be used for just about any task, while the other is designed to handle one type of ingredient with precision and accuracy.

If you’re an experienced chef or culinary student who needs a blade for fish and ingredients like it, then we highly recommend the Mioroshi Deba, especially if you deal with sushi and sashimi.

However, for those who need something that’s more flexible and can be sued as a go-to tool in the kitchen, the Gyuto would be your best pick.
