Key points of this article
Today's review: 3 key points
- The choice of steel depends on whether you prioritize "sharpness and ease of sharpening" or "rust resistance."
- The typical size for a vegetable knife is 165-180mm, which is the most manageable length for home use.
- It's practical to choose a knife based on the size of your hands, your cooking space, and how often you cook, by combining different types of steel and sizes.
The conclusion of this article (answer immediately):
- In short, when choosing a Japanese kitchen knife, you need to decide whether you want a steel-based knife that prioritizes sharpness or a stainless steel knife that prioritizes ease of maintenance. For a vegetable knife, choosing one that is between 165 and 180 mm in length will help you avoid making a mistake.
- Regarding steel materials, carbon steels such as white steel and blue steel are easy to sharpen and maintain their sharpness for a long time, while stainless steels such as molybdenum vanadium steel are rust-resistant and easy to handle.
- For a typical home kitchen, a 165mm vegetable knife is a good size, but if you have a large kitchen or frequently handle large vegetables, a 180mm knife will reduce stress during everyday use.
- The first thing beginners should focus on is clearly defining "how they will use it" and "how much time they can dedicate to maintenance" before narrowing down the steel type and size.
How should you choose the steel for a Japanese kitchen knife? Basic principles and considerations regarding steel.
In conclusion, the most important thing when choosing steel for a Japanese kitchen knife is finding the right balance between "sharpness and durability" and "susceptibility to rust and maintenance."
The reason is that the hardness, wear resistance, and rust resistance vary greatly depending on the type of steel used, which directly impacts daily usability and lifespan.
For example, choosing carbon steel such as white or blue steel will result in a sharp blade that is easy to sharpen, but frequent wiping and rust prevention are essential. On the other hand, stainless steel blades such as molybdenum vanadium steel are slightly less sharp, but they are rust-resistant and a convenient option for home use.
Characteristics of carbon steel (white paper and blue paper), which is common in Japanese kitchen knives.
In short, carbon steels such as white paper and blue paper are "steels for craftsmen who prioritize sharpness and ease of sharpening above all else."
White Steel No. 1 and No. 2 are known for easily developing sharp edges, and White Steel No. 2 is considered a standard steel widely used in professional kitchen knives. Blue Steel No. 1 and No. 2 are alloy steels containing tungsten and chromium, and are characterized by their long-lasting sharpness (the property of the blade remaining sharp for a long time).
However, these steel materials are prone to rusting and are susceptible to moisture and acid, so they require care such as washing and wiping them immediately after use, and in some cases applying a thin layer of oil.
Characteristics of stainless steel and molybdenum vanadium steel for cutlery.
In conclusion, stainless steel blades such as molybdenum vanadium steel are "steel materials that combine ease of use in the home with durability."
Molybdenum helps maintain hardness even at high temperatures, and vanadium enhances toughness after tempering, resulting in improved wear resistance and toughness. This makes it easy to achieve a balance between manageable sharpness and ease of sharpening at a hardness of around HRC56, and it is also relatively resistant to rust.
While its sharpness is slightly inferior to pure steel (white paper or blue paper), it is widely used in Japanese and Western kitchen knives for home use, making it a practical choice for households where frequent maintenance is difficult.
Key points for beginners when choosing steel materials
The first thing beginners should keep in mind is choosing steel based on "how often you need to sharpen it" and "how much effort you can put into preventing rust."
For example, if you enjoy sharpening your knives yourself several times a week and like to maintain them, then choosing white or blue steel blades is worthwhile. On the other hand, if you only want to have your knives professionally sharpened a few times a year, and you're not confident in wiping them down immediately after use, then stainless steel blades such as molybdenum vanadium steel are a safer choice.
We at our company also recommend starting with a stainless steel knife as your first knife, and then gradually adding a steel-based Japanese knife as you acquire more knives.
How to choose the right size vegetable knife? Practical guide to selecting the right one.
In conclusion, the most practical approach to choosing a vegetable knife size for home use is to start with 165-180mm as a baseline and then fine-tune it based on the size of your kitchen and the size of your hands.
A nakiri knife is a knife specifically designed for vegetables. It features a square blade and a long contact distance between the blade and the cutting board, making it ideal for julienning and chopping. Household nakiri knives typically range from 165 to 180 mm in length, similar to a santoku knife, making them easy to use in many households.
For a small kitchen in a single-person apartment, around 150mm is sufficient, but if you have a large cutting board and ample cooking space, 180mm or more is better. Choosing a size that suits your environment is key to avoiding mistakes.
Typical length and usability of vegetable knives
In short, for home use, you can't go wrong with a vegetable knife that's either 165mm or 180mm long.
A blade length of 165-180mm is equivalent to the standard blade length of a santoku knife, making it suitable for everything from large vegetables like daikon radish, Chinese cabbage, and cabbage to chopping herbs and spices. The straight blade tip and long contact distance with the cutting board make it easy to maintain a rhythmic julienne or mince cut, making it especially suitable for households that handle a lot of vegetables.
What's the difference between 165mm and 180mm?
In conclusion, the 165mm size offers ease of handling, while the 180mm size offers higher work efficiency.
The 165mm knife, with its shorter blade, is lighter and easier to maneuver, making it a convenient length for single-person households or those with smaller cutting boards and sinks. On the other hand, the 180mm knife, with its longer blade, makes it easier to prepare large vegetables and large quantities of ingredients in one go, making it suitable for larger kitchens or large families.
For those with small hands or who are unfamiliar with using knives, starting with a 165mm knife and then considering adding a 180mm knife as you become more comfortable is a reasonable approach.
Specific examples of how to choose based on the combination of steel material and size.
The most important thing is to consider the combination of steel type and size based on your own cooking style.
For example, if you're a household that cooks mostly vegetables every day and also enjoys the process of maintaining your knives, choosing a 165-180mm vegetable knife made of carbon steel such as White Steel No. 2 or Blue Steel No. 2 will give you both a sharp edge and ease of sharpening. On the other hand, if you mainly cook on weekends and don't want to worry too much about rust or dirt, choosing a 165mm vegetable knife made of stainless steel such as molybdenum vanadium will make it lighter, easier to handle, and require less maintenance.
Our company proposes a set that offers high long-term satisfaction, consisting of a 165mm stainless steel vegetable knife for everyday use plus a longer, more specialized steel vegetable knife or other Japanese kitchen knife.
