1. Know your knife steel
As a newcomer to the culinary world, you might be wondering why you should care about something as seemingly technical and esoteric as the different types of steel knives used to make your kitchen utensils. Because as long as your knife does its job and your food tastes delicious, doesn't that matter?
Not exactly! It's actually quite helpful to have a basic understanding of the different types of knife steels, even if you're just starting out in the kitchen. Knowing the different types of knife steels can help you choose the right tool for the job at hand.
Different grades of steel are better suited for different tasks. Understanding the differences between them can help you choose a knife that works well for the specific culinary tasks you have in mind. For example, a softer steel knife might not be the best choice for heavy cutting, but it might work well for slicing and dicing.
Understanding the different types of knife steels can also help you properly care for your knives. Different types of steel require different maintenance and care measures. So if you have a basic understanding of what your knife is made of, you can ensure it stays in top condition. This will help you to know which sharpening tool to use, be it sharpening rods, electric sharpeners or other sharpening kits. This includes things like storing your knife, cleaning it, and how often you sharpen it.
Of course, you probably don't need a metalworking degree just to be the husband of the house. But a basic understanding of the different types and their characteristics is really helpful in helping you choose and care for your kitchen blade.
2. Main properties of knife steel
First, let's get on the same page when it comes to what makes a steel knife good or desirable. There are many factors to consider, and many of these factors are interdependent. To achieve certain grades, other grades in steel compositions may need to be compromised. This can make the search for the "perfect" knife a balancing act. Therefore, finding the right knife is not as easy as many people think!
For example, in the development of stainless steel, part of the carbon needed for hardness must be replaced by elements such as chromium, which contribute to corrosion resistance. This means that stainless steel may not be as hard or as strong as other types of steel.
Hardness and toughness are important factors to consider when choosing a knife. Hardness refers to a knife's resistance to being scratched or cut and is usually measured using the Rockwell Hardness Scale (that's what it means when you see a knife advertised with a "Rockwell Score").
Toughness, on the other hand, refers to a knife's ability to resist chipping, cracking, or breaking under impact or twisting pressure. Knives that score high in these two categories, such as sporting and combat knives with shorter, thicker blades, are generally more durable.
If you want a knife that cuts through almost anything and stays sharp for a long time, pay attention to edge retention. This refers to a knife's ability to keep its edge sharp and maintain its cutting power over time. It is closely related to the hardness of the steel the blade is made of. As a general rule, harder steel will hold its edge better, but it can also be harder to sharpen when it eventually dulls.
Therefore, it is important to strike a balance between hardness and other factors that can contribute to a sharp edge, such as the presence of reinforcing elements and the natural malleability of iron. In other words, you want a blade that's tough enough to take a beating, but also has a little bit of flex so you can easily brush up the edge when it starts to dull.
Wear resistance refers to a blade's ability to withstand severe abuse and still maintain its sharp edge. In general, steel with a high concentration of carbides (also known as carbon content) is more resistant to wear and steel with a high carbon content is generally very hard.
But here's the thing: if a knife is too hard, it may be more prone to chipping or breaking under pressure. Therefore, it is important to find a balance between hardness and toughness. You want a blade that will stand up to heavy use but also be durable enough to withstand the wear and tear of everyday use. That is, a knife that is badass but also gives a little.
Corrosion resistance refers to a knife's ability to resist rust and maintain its smooth, shiny appearance over time. While any steel can rust under certain conditions, you may find blade materials with higher levels of corrosion-resistant elements such as chromium (as in stainless blades) that are less prone to rust.
Keep in mind that other properties such as strength and wear resistance may need to be compromised to achieve good corrosion resistance. In other words, you might have to sacrifice a little toughness to get a blade that's less prone to rust. Which brings us back to the balancing act we talked about.
3. The most popular/used types of steel knife
According to many knife manufacturers, most knives are made of tool steel, stainless steel or carbon steel. Each of these types of steel has unique properties and is suitable for different types of knives.
Tool steel is a hard, tough material that can be alloyed to improve other properties. It is often used on knives that are subject to heavy use as it can withstand a lot of stress. Tool steel is also very heat resistant, making it a good choice for cutting tools. However, it may not be as corrosion resistant as stainless steel and may not have the best finish for certain types of knives, such as utility knives. B. kitchen knives.
- Tool steel is known for its toughness and ability to withstand intense wear and tear. Tool steel knives are less likely to chip, break or warp under pressure than other types of steel.
- Tool steel has good edge retention and is less prone to dulling than other steel grades. This means tool steel knives need to be sharpened less often and stay sharp longer.
- Some grades of tool steel are very resistant to corrosion, making them suitable for use in wet or outdoor environments.
- Tool steel tends to be more expensive than other types of steel, which can make it less affordable for some knife makers.
- Tool steel can be difficult to machine due to its high toughness and wear resistance. May require special equipment and techniques to form and finish.
- Some grades of tool steel can be harder to find or obtain than other grades of steel, which can make it difficult to source knife-making materials.
- Tool steel often requires a complex heat treatment process to obtain optimal properties, which can be time consuming and requires specialized equipment. Obviously knife makers need to heat treat these tools, not the end user.
- Not a good steel for kitchen knives.
When it comes to kitchen knives, stainless steel is arguably the most popular choice as it has a number of desirable qualities. One of the biggest advantages of using stainless steel for a kitchen knife is its resistance to corrosion, which is extremely important in a humid environment like a kitchen. This means the knife is less likely to rust over time, which can affect its performance and appearance. Stainless steel knives are easy to care for.
Stainless steel is also known for its appearance, which can give the knife an attractive and professional appearance. While not as hard as tool steel or carbon steel, it's still a durable option that will stand up to regular use in the kitchen. And not only that, they look great.
In general, stainless steel is a good choice for kitchen knives as it resists corrosion and has a beautiful finish, making it a practical and visually appealing choice. It is particularly useful for knives used in wet or humid environments, as it is less prone to rusting in these conditions.

- Some grades of stainless steel can be more expensive than other grades of steel, potentially making them less affordable for some consumers.
Carbon steel is a type of steel often used to make knives because it produces a very sharp blade that is easy to sharpen. It is also very hard and strong, making it a good choice for blades that are subjected to heavy use and need to withstand a lot of wear and tear.
However, a disadvantage of carbon steel is that it is not very resistant to corrosion and is therefore more susceptible to rust than stainless steel. This can affect appearance and performance. Despite these drawbacks, carbon steel is still a popular choice for certain types of knives, especially those that are used a lot and require a strong, sharp blade.
Several knife blades use carbon steel. A great example of this isdeboning, which must be difficult because it is used for difficult jobs. Being made of carbon steel, it has more than enough strength to get the job done.
- Carbon steel holds fine edges well and is less prone to dulling than other types of steel. This means that carbon steel knives need to be sharpened less often and stay sharp longer.
- When it comes time to sharpen, carbon steel is generally easier to sharpen than stainless steel, which can make it more convenient to get a sharp edge. Even those standard manual knife sharpeners will take great advantage of this.
- Carbon steel is known for its toughness and ability to withstand heavy use and wear. Carbon steel knives are less likely to chip, break or warp under pressure than other types of steel.
- Carbon steel is known for its ability to cut sharp edges quickly and easily, which can make it more responsive and accurate in use.
- Carbon steel is susceptible to rust and other forms of corrosion if not properly cared for. This means it requires more maintenance and care to prevent rust or discoloration.
- Carbon steel can become prone to staining when used to cut acidic foods or when not properly cleaned and dried after use.
- Carbon steel can be difficult to machine due to its high toughness and wear resistance. May require special equipment and techniques to form and finish. However, this will only really be an issue for knife makers, not the end user, so you probably shouldn't worry about it.
Damascus steel has a long history, originally used to make swords and other bladed weapons dating back to the ancient city of Damascus. Its local blacksmiths were considered the best in the world thanks to their unique knife-making techniques. Not only did it result in a very useful steel, it was also known for its beauty.
