Today's review: 3 key points

The steel used for Japanese kitchen knives comes in three main types: carbon steel, stainless steel, and hybrid (clad) steel.

The typical length of a vegetable knife is 165-180mm, and this range can be considered the standard size for home use.

The best combination of steel and size will vary depending on "who does the cooking and how much" and "the size of the kitchen."

Conclusion of this article

In conclusion, for your first knife, a stainless steel or laminated steel vegetable knife around 165mm in length is the safest choice and least likely to disappoint.

If you cook frequently and prioritize sharpness above all else, you should choose a carbon steel knife such as Aogami or Shirogami, with a 180mm vegetable knife blade, prioritizing long-lasting sharpness and work efficiency.

In short, the basic rule is "stainless steel + 165mm if rust resistance is the priority" and "carbon steel + 180mm if sharpness is the priority."

Most importantly, you need to consider whether the characteristics of the steel (susceptibility to rust, edge retention, ease of sharpening) and the size of the vegetable knife suit your needs.

The first thing beginners should understand is the "characteristics of each type of steel" and the "difference between 165mm and 180mm vegetable knives" before comparing products.

What kind of steel is used for Japanese kitchen knives? Carbon steel or stainless steel, which should you choose?

Choosing the right steel for a Japanese kitchen knife boils down to finding the right balance between sharpness, edge retention, rust resistance, and ease of maintenance. In short, carbon steel is suitable for those who can perform meticulous maintenance, while stainless steel or laminated steel is a more practical choice for home use where ease of handling is a priority. To summarize, it's helpful to remember that "carbon steel = performance-focused, stainless steel = ease of handling-focused, and laminated steel = best of both worlds."

Characteristics of carbon steel (high-carbon steel) Japanese kitchen knives and who they are suitable for

Carbon steel is a type of steel that contains a high amount of carbon, and is known for its excellent sharpness and edge retention, as exemplified by Yasugi steel such as Shirogami and Aogami. Aogami has higher wear resistance and longer-lasting edge retention than Shirogami due to the addition of alloying elements, making it suitable for large-scale cooking and long-term work. On the other hand, carbon steel is prone to rusting, requires thorough maintenance such as wiping off moisture and drying after use, and hard types like Aogami Super are difficult to sharpen, making them more suitable for intermediate to advanced users who are familiar with handling knives.

The reason why stainless steel Japanese kitchen knives are "popular for home use"

Stainless steel, with its high chromium content, boasts excellent rust resistance and ease of maintenance as its greatest strengths. High-grade stainless steel knives offer sharpness comparable to carbon steel, and are considered more than sufficient for home use. Furthermore, the number of dishwasher-safe all-stainless steel knives is increasing, making them suitable for shared kitchens and busy dual-income households. In short, it's a steel material for those who prioritize ease of use over sharpness.

The option of using laminated steel (hybrid structure)

The laminated construction is a three-layered knife structure where carbon steel or high-grade stainless steel is used as the core material responsible for sharpness, and both sides are made of rust-resistant stainless steel. This structure allows the blade tip to have the sharpness of carbon steel, while the sides are rust-resistant with stainless steel, reducing the burden of daily maintenance. For beginners, the first thing to keep in mind is that "a single-piece carbon steel knife is for those who are confident in their maintenance skills, while a laminated knife is somewhere in between," making it a well-balanced choice for a first knife.

Choosing the Right Size for a Vegetable Knife: What's the Difference Between 165mm and 180mm?

The most frequently asked question when choosing the size of a vegetable knife is, "Which is better, 165mm or 180mm?" In conclusion, for a typical household, 165-180mm is the best range. If your kitchen is small or you have small hands, 165mm is recommended, while if you cut a lot of vegetables or enjoy cooking, choose closer to 180mm. In short, a simple guideline is, "If in doubt, go with 165mm; if you cook often, go with 180mm."

Common lengths and standards for household vegetable knives

The typical size for a vegetable knife is a blade length of 165-180mm, which, like the santoku knife (a multi-purpose knife), is considered "the most convenient length for use on a home cutting board." While some people living alone or with very compact kitchens may choose a shorter size of around 150mm, 165mm is the standard size for versatility. Conversely, for large families or households that chop large quantities of vegetables at once for meal prep, a 180mm vegetable knife allows for more cutting board space and improved work efficiency.

Kitchens and people for whom a 165mm vegetable knife is suitable.

A 165mm vegetable knife is a good match for standard-sized cutting boards and typical sinks, making it the most recommended length for households introducing a vegetable knife for the first time. It's easy to handle even for people with small hands or those who are not comfortable with knives, and its moderate weight makes it less tiring to use during daily cooking. In short, it's a "universal length that's hard to go wrong with," and it's a convenient size for switching from a santoku knife or as a secondary knife.

Advantages and points to note when choosing a 180mm vegetable knife

A 180mm vegetable knife truly shines when cutting large vegetables and fruits such as cabbage, Chinese cabbage, and watermelon, as its large blade allows you to cut through them in one go, shortening the work time. Additionally, the longer blade allows you to handle a wider range of ingredients at once, and the strokes for julienning and mincing are more stable. On the other hand, it can feel cumbersome in small kitchens or with small cutting boards, so it's important to check the balance between the knife and the size of your cutting board and storage space beforehand.

The relationship between steel material and size | What is the best combination?

In short, the key point regarding the relationship between steel type and size is that "the weight, balance, and ease of maintenance change, so even with the same length, the feel of use will differ." In conclusion, a practical approach is to consider that a 165mm blade made of slightly heavier carbon steel will have sufficient volume, while a 180mm blade made of lightweight stainless steel will be easy to handle. Most importantly, "consider the characteristics of the steel type and the blade length together, in relation to your own hand and kitchen."

Recommended steel types and vegetable knife sizes based on cooking frequency

If you cook infrequently (a few times a month to once a week), a 165mm stainless steel vegetable knife is a practical choice, prioritizing lightness and ease of handling. For those who cook at home several times a week or more, choosing a 180mm knife made of laminated steel or high-grade stainless steel offers a good balance of sharpness and ease of maintenance. For cooking enthusiasts or those aspiring to be professionals who handle large quantities of ingredients daily, a 180mm vegetable knife made of carbon steel such as Aogami or Shirogami is a suitable choice, as it offers superior long-lasting sharpness at the expense of frequent sharpening.

Compatibility based on hand size and kitchen size

For those with small hands or weak grip strength, a lightweight stainless steel or thin-bladed laminated steel knife with a 165mm blade is easier to handle and provides greater confidence in knife control. Conversely, those with larger, stronger hands may find a slightly heavier carbon steel knife with a 180mm blade less tiring to use, and its smooth cutting action makes for stress-free work. For compact apartment kitchens, a 165mm blade is recommended, while for larger system kitchens or commercial spaces, a 180mm blade length will help maintain balance with the cutting board and sink.

Three steps to choosing a watch you'll keep for a long time.

The most efficient way to choose a knife that you'll use for a long time is to narrow down your options based on three factors: ① how often you cook and your willingness to maintain it, ② your kitchen environment and hand size, and ③ your budget and level of preference. For example, if you "cook at home every day and enjoy sharpening it," a carbon steel knife with a 180mm handle might be suitable, while if you "cook a few times a week and want something easy to maintain," a stainless steel or laminated knife with a 165mm handle might be better. The combination will depend on your specific needs. Finally, when choosing a specific product, check the place of origin (e.g., knives from Seki City), the manufacturer, and the shape of the handle, and use whether it actually feels comfortable in your hand as a criterion to avoid making a mistake.
