The Deba knife is a traditional Japanese knife, that’s primarily used for cutting fish. The knife has been specifically designed for tasks such as filleting fish and removing the fish’s heads. In addition to that, it can, of course, be used for cutting other meat.

Thanks to its significant weight, the knife can handle small bones that may, for example, be encountered when breaking down a chicken. However, larger bones should be avoided, as the knife is not designed for them and they may cause damage to the edge of the knife. The area near the handle is the best part of the edge to use for bones.

The spine of the Deba knives tapers along its length, which results in a surprisingly thin tip. Thanks to this thin tip, the knife can be used even for some delicate tasks such as removing bones.

The center area of the edge is best used for slicing.

Traditionally, carbon steel was utilized for these knives. As you may know, carbon steel requires maintenance. Therefore, modern Deba knives are mostly made of stainless steel, which doesn’t require as much care.

Top 7 Recommended Deba Knives

Let’s have a detailed look at some of the popular Deba knives.

Yoshihiro Shiroko High Carbon Steel Kasumi Deba

Yoshihiro Shiroko High Carbon Steel Kasumi Deba Japanese Fillet Chef's Knife 7inch(180mm)
  • Grade: Kasumi / Knife Type: Deba ( Fillet, Butcher )Knife
  • Steel Type: Shiroko (White Steel 2) High Carbon Steel
  • Blade: Single-Edged/ Blade Length : 7" (180mm)

This is a beautifully handcrafted Deba knife with a 7-inch blade finished in the Kasumi style. The Kasumi style refers to a mist pattern on the blade that is created by forging the steel with iron. The blade is single-edged and is meant for right-handers. If the 7-inch blade is not ideal for your needs, there are also variants with 6.5-inch and 8.5-inch blades.

You can choose between magnolia wood or rosewood handle. Personally, I would go for the lighter magnolia wood, because it goes together well with the included wooden Saya cover.

Because it is a knife made of high carbon steel, it’s vital to take proper care of it. The manufacturer recommends applying Tsubaki oil before storage.

We have reviewed some other Global knives before, and they were all pretty solid knives. The same can be said about Global’s take on the Japanese Deba knife.

It has a slightly different shape to the blade’s spine and tip than you’d expect from the Deba knife, but it still works great. The blade is 7 inches long and has a single edge design.

The knife is made of Cromova 18 stainless steel, which retains sharpness very well. The handle is molded from stainless steel as well and it has the traditional Global dimpled texture to it. This provides a safer grip.

Overall a solid knife that can be had for a reasonable price.

How To Choose The Best Deba Knife?

Let’s have a look at some of the factors one should consider when shopping around for a good Deba knife.


From the size point of view, there are many choices available because various species of fish are caught in Japan. You wouldn’t want to use a huge 8-inch knife on a tiny fish, right?

In essence, choose the right size for the tasks you are planning to use the knife for. If you are looking for an all-purpose choice, I would probably recommend a knife with a blade around 6 or 7 inches long.


Deba knife blades are traditionally designed as single bevel (or single edge), although nowadays, double-edged models are available as well. If you are going for a single edge one, make sure you get the right one based on whether you are right or left-handed. The bevel should be on the left side for left-handers and on the right side for the right-handers. Double-beveled Debas can be used universally.

Another important aspect of the blade is the material it’s crafted from. Nowadays most of the Deba knives are made of stainless steel to allow for easier maintenance. The traditional Japanese Debas will, however, have high carbon steel blades that can be susceptible to rust and stains. In case, you of those, it’s vital to take proper care of the knife. That means no dishwasher, keeping the knife dry, storing it in a dry environment, and regular use of maintenance oil.


The traditional Japanese Deba-bocho comes with wooden handles and I think that’s the right choice here. Wood is a nice-looking material, that can stand the test of time and provides a comfortable and firm grip.

If you are a fan of plastic or metal handles, you won’t be disappointed either as there is a wide selection of Deba knives with those as well.


Price is pretty much always going to be one of the deciding factors for most of us. Know, that the selection of knives, in general, is huge. There are many Deba knives to choose from with prices starting at 15 dollars or so. Some of them, of course, are not going to be very good, but there are some good choices among the cheap Deba knives as well.

On the other hand, if money is not an issue, you can get an exquisite Deba by Yoshihiro, that will set you back by more than 1000 dollars.

Frequently Asked Questions

Is the Deba knife only for fish?

Although the Deba knife’s primary purpose is cutting fish it can also be used to cut vegetables or meat in many different ways. It can be used for chopping, cutting, slicing, and mincing meats, herbs, vegetables, and fruits as well.

How do you sharpen a Deba knife?

The Deba knife should be sharpened periodically to ensure the best cutting performance. The edge of the knife is typically sharpened by using whetstones. Learning how to sharpen a Deba knife is not difficult, but it does require some patience and practice because most Deba knives are single-edged. First, you have to sharpen the whole cutting edge and the tip of the knife until a burr shows up on the other side of the blade. Then you remove the burr by laying the blade flat on the whetstone and moving it back and forth a couple of times. Don’t use too much pressure and don’t sharpen the flat side at an angle.
