Conclusion of this article

• In conclusion, for professional deba knives, both White Steel No. 2 is chosen as a standard steel because it is "easy to sharpen and has a sharp edge," while Blue Steel No. 2 is chosen because it "maintains its sharpness for a long time and is resistant to chipping."
• In short, in a workplace where fish are being prepared all day long, the balance between "ease of sharpening" and "longevity of sharpness" is paramount, and in that respect, White Steel No. 2 and Blue Steel No. 2 are materials that meet the demands of professionals.
• The most important thing is to decide whether to use a white steel or blue steel blade based on your own work environment (amount of fish prepared, frequency of sharpening, types of fish handled).
• The first thing beginners should understand is that "a higher price doesn't necessarily mean blue paper is superior; both white and blue paper have their own unique advantages."
• If you're looking for a professional-grade knife, it's crucial to have a forged deba knife made of either white steel #2 or blue steel #2, along with a reliable sharpening and maintenance environment.

What are the basics of Japanese kitchen knives, steel materials, deba knives, professional-grade knives, and Merit?

In short, the choice of steel for a professional deba knife is determined not only by "how sharp it is" but also by "how consistently and for how long it maintains its sharpness."

Because a deba knife is used to cut off the head of a fish and fillet it into three pieces while pressing it against the backbone and central bone, the blade is subjected to heavy stress, making it prone to chipping and wear.

Therefore, in the professional world, along with sharp cutting edge, the steel's properties such as "resistance to chipping," "ease of sharpening," and "longevity of sharpness" are the most important factors influencing the performance of a deba knife.

Representative steel materials used in Japanese kitchen knives include Hitachi Metals' Yasugi Steel series, which includes white steel, blue steel, and silver steel.

Among these, "White Steel No. 2" and "Blue Steel No. 2" are frequently cited by many specialty shops as suitable steels for deba knives, with each having a clearly defined role and recommended uses.

The first thing beginners should understand is that "White Steel No. 2 = standard for ease of sharpening and sharp cutting edge" and "Blue Steel No. 2 = balanced type with long-lasting sharpness and toughness."

Why professionals choose high-carbon steel for their deba knives

In conclusion, the main reason professionals choose carbon steel for their deba knives is that "it's easy to achieve a sharp edge, and you can create your preferred blade shape through sharpening."

According to guides from specialty knife shops, fish is a delicate ingredient, so a sharp, high-carbon steel is suitable for a deba knife, and White Steel No. 2 and Blue Steel No. 2 are recommended as professional-grade steels.

While steel is more prone to rusting than stainless steel, it has excellent compatibility with whetstones and is a material that is easy to sharpen, making it a firm favorite among chefs.

In professional settings, sharpening knives with a whetstone before and after each day of business is a given, so the ease of use of steel, which can be restored through sharpening and transformed through sharpening, is a major advantage.

For fishmongers and Japanese restaurants that prepare fish all day long, a dull blade directly leads to a decrease in preparation speed, so choosing a steel that is easy to sharpen is important from a productivity standpoint.

The most important thing is to understand that for professionals, knives are not consumables, but rather "partners" that are used and sharpened regularly.

Professional-grade benefits of White Paper No. 2 steel

In short, White Steel No. 2 is a standard steel material that is easy to sharpen and combines a sharp cutting edge with moderate toughness.

According to the description of Yasugi steel, White Steel No. 2 is described as the most commonly used steel for professional kitchen knives, and is said to have a good balance of hardness, sharpness, and ease of sharpening.

Especially for knives like deba knives, which are prone to chipping or breaking when they hit bone, the ease of sharpening White Steel No. 2, which allows for quick repair of chips through sharpening, is a major advantage.

For filleting fish and removing the heads, a deba knife requires frequent sharpening, so "a steel that is easy to sharpen and resistant to chipping, such as White Steel No. 2, is considered the most practical."

Furthermore, it is said that white steel contains fewer impurities, making it easier to achieve a razor-sharp cutting edge, and is suitable for thin slicing and delicate cutting work.

The first thing beginners should understand is that "White Steel No. 2 is a well-balanced steel that is often chosen as the first rod for both professional and beginner players."

Professional-grade advantages of Aogami No. 2 steel

In conclusion, Aogami No. 2 is a professional-grade steel that combines the sharpness of Shirogami with long-lasting sharpness and toughness, and truly shines in demanding work environments.

Blue Steel is described as an alloy steel made by adding chromium and tungsten to White Steel No. 2, resulting in a material with enhanced wear resistance and long-lasting sharpness.

Aogami No. 2 steel has a good balance of hardness and toughness (resilience), and is considered suitable for professional work environments where preparation takes a long time, as it is a steel that "maintains its sharpness for a long time and is resistant to chipping."

Even in explanations from specialty cutlery shops, it is said that "Aogami No. 2 steel is ideal for deba knives, where durability is required due to the nature of the work," and it is used by craftsmen who continue to prepare fish all day long.

However, since blue steel is harder than white steel, it has the disadvantage of taking longer to sharpen, making it a material best suited for professionals who prioritize long-lasting sharpness over sharpening time.

The most important point is that the professional advantage of Aogami No. 2 steel is that "while sharpening becomes more difficult, the number of sharpening sessions can be reduced."

How to Choose a Japanese Kitchen Knife: Steel, Deba Knife, Professional Use, and Benefits

How should I choose the steel for a professional deba knife?

In conclusion, the most rational way to choose the steel material for a professional deba knife is to consider the frequency of sharpening and the quantity and hardness of the fish being handled.

For example, in workplaces where many fish are handled daily and there isn't enough time to sharpen knives multiple times during business hours, choosing a steel material that "maintains its sharpness for a long time, like Aogami No. 2," can reduce the frequency of sharpening and the stress during work.

On the other hand, for craftsmen who want to meticulously sharpen their knives and adjust the blade to their liking, the ease of sharpening "White Steel No. 2" is a major advantage.

It's important to choose the right steel for your intended use, keeping in mind the differences in characteristics: White Steel No. 2 is "easy to sharpen and allows you to adjust the sharpness to your liking," while Blue Steel No. 2 is "a hard steel that maintains its sharpness for a long time."

Furthermore, it is said that the choice between "the razor-sharpness and ease of sharpening of white steel" and "the tough characteristics of blue steel" is a matter of preference and intended use, and that white is not necessarily superior to blue.

The first thing a beginner should understand is to decide whether to use white steel or blue steel based on their own sharpening skills and the amount of material they prepare.

What are the key forging and structural requirements for a professional-grade deba knife?

In short, for professional deba knives, the quality of the forging and the blade structure are just as important as the quality of the steel.

Many professional-grade deba knives use Yasugi steel (white or blue) as the core material, and are constructed with a three-layer structure formed by forge-welding and forging together with soft iron or base metal.

Forging creates a denser metal structure, increasing its toughness and strength. This makes it less prone to chipping or breakage, even under the harsh conditions of continuous contact with bone, as is typical for deba knives.

Some professional-grade deba knives forged from Aogami No. 2 steel are described as achieving both lasting sharpness and toughness through "the toughness of Aogami No. 2 steel and the durability of forging."

Furthermore, the requirements for professional-grade tools include "durability due to forging," "steel with a sharp cutting edge," and "appropriate thickness and weight," suggesting that not only the name of the steel but also the manufacturing method should be considered.

The most important thing is not just to look at the names "blue paper" or "white paper," but to see how the steel is forged and finished.

How can you utilize the benefits of professional-grade steel materials in a home setting?

In conclusion, professional-grade deba knives made with high-quality steel (White Steel No. 2 and Blue Steel No. 2) offer significant advantages for home cooks who frequently prepare fish and are willing to take the time to sharpen them.

A deba knife made of Aogami No. 2 steel is a practical choice for those who want to fillet a large quantity of fish at once on their days off, or for fishing enthusiasts who want to properly process large catches at home, as it reduces the frequency of sharpening.

A deba knife made with White Steel No. 2 is suitable for advanced home users who want to enjoy the time spent sharpening it with a whetstone and pursue their preferred blade finish.

However, since all of them are made of carbon steel, which is prone to rusting, it is essential to wash them immediately after use, wipe off any moisture, and let them dry.

Regarding sharpening, regular maintenance using a whetstone is essential, so for those who want to minimize maintenance, a deba knife made of professional-grade stainless steel such as Gin-san stainless steel is recommended.

The first thing beginners need to understand is whether they can accept the premise that "using professional-grade steel materials at home means that maintenance will also be more professional-level."
