What is the Deba knife or Deba Bocho?

In Japan, Bocho means knives. And Deba Bocho indicates a pointed carving knife. You can also call the blade Hon Deba or Boning Deba.

The unique knife is famous from the early Edo period. Japanese people use it for cutting fish, meats, separating fillets, etc. They always prefer the former while comparing Deba vs fillet knife.

But never try to chop the strong bones with it because it has a carbon steely tapered blade and a stout handle with a sharp age. This combination is only suitable for delicate works. There are various shapes and sizes. Usually, the knives come with 180 mm to 330 mm lengths. Among them, 150-180 mm is suitable for the home. Most of the Deba knives used stainless steel blades for the highest quality. But the professionals prefer the large size.

Deba knife or deba Bocho is mainly used for fish/meat butchery. You can cut them into small pieces. These flexible fillet and butchering knife will help you deal with both fresh and frozen food.

Besides, Chefs use it to fillet the fish. As a regular cook, you might know that fish heads are a hassle to handle. But Deba is the king here.

Buying guide for the best Deba Knife Brand

Blade materials

One of the essential parts of a regular Deba knife is its blade. This blade material ensures ease of cutting. Manufacturers use high-grade stainless steel in Knives. But there are two types of blades. Such as

Stainless steel blade:

Stainless steel uses the least amount of aluminum. It makes the steel rust-proof. Typical knives use sets as the necessary materials.

Carbon steel blade:

On the contrary, carbon steel is suitable for traditional knives. Because it is rust-resistant, so it can give you durable service. As a chef, you want to retain the sharpness of your favorite tool. If so, then go for carbon steel. Though they need high maintenance, the carbon steel materials have a sharp edge, giving you a professional output.


The knife’s handle is another vital part of knives. Think for a while; if you can’t grab a blade with flexibility, then your task will turn into a disaster. So take care of it before investing money. Traditionally most debts had a wooden handle.

Though recently they have plastic and metal handles, the wooden handle has its demand. Because it can give you a firm grip. Additionally, according to the shapes, Deba knives have two types of handle also.

Yo Shape or Yo Debe Knife:

Yo handles are the modified version of typical western handles. There might be a bolster or not. It is an extended tang also. Most of the best western Deba knife comes with a similar handle like it.

Wa Shape or Wa Deba Knife:

On the other hand, most of the traditional Japanese manufacturers used Way handles. They are in D or Octagon Shapes with a wide blade diameter of 1 inch. This Mongolia wooden shape is easy to maintain.

Moreover, you have to choose the handles according to your active hand. If you are involved with the left hand, then select D-shape to handle. And righties are God’s favorites. That’s why they find all the shapes easy to handle.

Blade Features

Deba has an asymmetrical blade finish, which means there is a single-sided sharp edge; the blade has a bulky thickness with a hollow ground at the back. So the tip won’t bend easily. Here you will get a long-lasting service.

Though most of the Japanese brand is of straight edge, Deba knife is notable for its curving edge at the bottom. It is called a pointed knife due to the extra thin curved base.

You have to prioritize some essential qualities, like whether the blade is retractable or fixed to use. Because the quick mechanism of blade changing offers an extra privilege in your cutting, you can quickly move with it.

One of the essential things is enough storage of your specific blade. Otherwise, you have to change the whole set.

Size is another factor for full-fledged work. Deba has a 6-10 inches size blade within e 2/3 inches height.


The more thin edge gives you the more sharpness. It has an extraordinary sharpness to divide the bones or heads of a fish/meat without affecting it.

You may ask if it has severe sensitivity, so why can’t we chop matured bones with it. This is because bones need high pressure to the edge and handle. And it can affect the—knife’s structure.


This knife has a heavyweight handle and blade with a fragile edge. Maybe this is the only limitation of the blade. Because people like to handle lightweight objects.

However, we can’t give the traditional knife a negative point just for its heavyweight. Deba is designed like that. This weight helps to bring an absolute slice of your fish.

If you go over any Japanese Deba knife review, you will find people mostly complaining about the weight. However, we believe it’s the weight that makes this knife unique in precision.

Western versions like the Wusthof classic Deba knife are lighter in weight. However, you may not find the same power in the Wusthof Deba knife that you will get from a Japanese one.


Okay, that’s the central fact you should consider. As you know, there is no limit to the best products. But you have to choose one of the best products within your budget. If you want a budget-friendly Deba knife, then you can select the range from 15USD.

In any sekiryu Deba knife review, you will find how the price has affected people’s preferences. Due to its higher cost, home cooks prefer the western Deba knife. But if you are pro-cook, there is no better choice than an authentic one.

On the other hand, if product quality is your main concern, then at best near about 1000 USD, you will get a unique piece of Deba knife. So the choice is yours. This might trigger your confusion. That’s why we will suggest you go with our list. Hopefully, most of them will fit within the budget.

Don’t get confused with a German steel fillet knives. They are perfect for filleting but not as versatile as Deba. These single bevel knives are sharp and can take care of any food. 

How to Take Care of Your Deba Knife Handle?

Besides, manufacturing companies put oil in the wood to make it waterproof. Without proper maintenance, it will be fragile within a short time. So follow the steps to increase the lifespan of a knife handle.

  • Wood damages when it gets water. So store your knife in a dry place. And make sure to give it a dry wash. Don’t even dip it in water for a second.
  • Avoid heat exposure. Excessive heat from stoves may burn your knife handles
  • The Shiny handles look nice. Polish your knife handles with oil (Tsubaki oil) after a dry wash.
  • Don’t soak it in oil or polish with rough papers. Take oil in your palm and rub on the whole structure. It helps the blade to remain stainless also.

Some FAQ About Japanese Deba

  1. What size is a Deba?

    Japanese people like to have more fish preparations, so they have a wide range of debt knives. They differ in sizes and lengths also. Like Ajikiri Deba, Ko- Deba, Hon Deba, etc. Among the first two are small in size, and Hon or Bocho is of the typical size.

    There are 10-27 cm sized knives wherever 15-18cm is the standard size. It depends on you which one you want to use. No matter which one you pick, these Japanese style knife will give you a precise cut with an extremely sharp blade.

    So first, identify the size according to the fish/ meat shape. Because the best size deba knife is more extensive than flesh, you can’t handle it.

    On the contrary, if the fish is more extensive, you need to press its belly to cut, it will lessen the freshness. So try to take a regular size knife (15-18 com) for as usual cutting. Choose a larger one (19-20 com) for excessive quantity or professional dealings.

  2. Can I Cut a Fishbone with Deba Knife?

    It depends on the fish category and the thickness of the bone. You will find some excellent correlation between the blade and meat in any Yo or sekizo Deba knife review.

    Deba is indeed famous for fish butchery. You can cut the delicate bones easily of small size fishes with the upper half blade. But if the bone is more substantial enough, then you should change the decision.

    So our suggestion is to bring the fish on your chopping board first. Then decide based on its size and thickness.

  3. Can I use Deba Knife for filleting fish?

    Yes, of course, you can use it in fish filleting.

    The traditional Japanese knife is mainly designed for filleting fishes. Nothing can beat it. So if you want to start from the beginning, just go for it.

    The primary filleting method involves a phase, ‘San nai oroshi.’ In this step, a Japanese slice a fish into three layers. So with hon bocho, you can go deep into the fish or poultry and have a thin slice of flesh with the pointed tip.

    Then the back part of the knife requires more pressure to remove the bones from the flesh. The detaching system is popular in Japan as ‘boning’

  4. Which knife Sushi Chefs Use?

    Most Sushi Chefs use Deba and Usuba knife to make their recipes.

    Sushi is tasty food around the world. As the recipe is a little bit sophisticated, so it requires a professional touch to get yummy food on your plate. Moreover, the taste of Sushi depends on its flavor. And deba knife can give thin slices of fleshes, keeping the flavors and texture fresh. It results in a top- reviewed Sushi.

    Experienced chefs can do fillets and remove the fishbone in a glimpse of the eye. So, they like to use deba rather than any other kitchen knife for Sushi. You can choose this knife for home-made Sushi. But, be aware of slicing. You may hurt yourself for the first time

  5. Why Deba knives are made of Carbon steel?

    Nowadays, you will get enough Deba, which uses stainless steel as its base. But the authentic Deba knives manufacturer prefers to use Carbon steel. Carbon steel has more than 10% alloy, which makes the blade stout and prevents early damage.

    On top of that, Carbon steel is rust-resistant. That means your knife will stainless for a long time and provide you durable service. In addition to that, any knife will blunt with the reparative use. Carbon steel is easier to sharpen than stainless one. This may also be a reason why Deba knives are made of carbon steel.  

  6. How do you sharpen your deba Knife?

    A sharp knife is the prerequisite of any best dish. If you deal with a blunt knife for a long time, it will shorten knives stability. So it is a crying need to sharpen your knife at a regular interval.

    Traditional way:
    This method doesn’t require any special tools. You can use an ordinary Stone with sand, or a simple whetstone will be enough. The process is a little bit tricky. You have to place the knife over the stone and choose a convenient angle and move the blade. Follow the process steadily, or you can cut your fingers.

    Electric Sharpener:
    Sharpening with an electric sharpner. It is fun. Just place the knives on the sharpener and switch it on. Within a few seconds, your knife will be new again.

Final Verdict

It is time to make a final decision. Actually, the debate of which is the best deba knife has no conclusion. All of them are best in their own compatibility. Mainly the user can identify what he needs more. I’ve discussed ten blades there.

If you are a beginner, then go for BIGsunny brand. And when you are used to, then you may choose Yoshishiro brands. On the other hand, if you prefer an all in one brand, buy Kei Saki knife. For a unique Japanese dish, you opt for BIGSuNnY again.

Last but not least, budget concerns. Though most of the knives are budget-friendly, if you care for quality, choose any from the Yoshihiro brand.

Personally, I will suggest, don’t be so confused, and be confident. Cooking is a sweet battle, where a knife is its sword. So identify your concern, and then invest money. Start with the basic one. And day by day you will be the master of it…Happy cooking!
