Many people, when first starting out on the path of professional Japanese knives, will often hear the term “Damascus Steel”. Beginners (as I once was) are often confused by the many types of knives and the quality of the steel used to make them. You’ll also wonder about many choices: “Damascus Steel vs. Carbon Steel”.
The fact is, modern Damascus steel is not the legendary Damascus steel of old. I’m not sure which type of steel you want to learn about, but in this article, I will compare both with carbon steel.
What is Traditional Damascus Steel?
Damascus steel is not just one type of steel. It is a collection of closely related steels, produced by various craftsmen using similar but not identical techniques and raw materials. Technically, it is not truly “Damascus” steel but rather steel that originated from India and Sri Lanka.
Firstly, it’s important to understand that Damascus steel is a general term for the final product, primarily used in blades and especially in swords. It is famous for its durability, ability to create extremely sharp, hard, yet flexible blades that can bend more than most other steels and still return to their original shape with minimal damage, and for its distinctive “watered” pattern. These characteristics made Damascus blades superior in their time. Today, we have steels that surpass Damascus steel in most respects. In your kitchen, you might own knives that are better than Damascus steel in every aspect, but this is true only in the present. In its time, Damascus steel was the most advanced.
In ancient times, metallurgy was based mainly on “trial and error” and a lot of luck. People did not understand the elements like iron, carbon, chromium, molybdenum, vanadium, or other metals, and especially did not understand how they combined to form metal carbides, nanowires, carbon nanotubes, etc. Without this knowledge, they couldn’t test the ore, intermediates, and final products to identify special factors.
Damascus steel originated from Wootz steel, produced in India, Sri Lanka, and nearby regions from around 600 BCE. This was high-quality steel with high carbon content, very pure, and free from slag, with carbon levels around 1 to 1.5%. Wootz steel was traded globally, but its quantity was limited, and quality decreased the further it traveled from the source.
After 700 CE, the Arabs traded extensively with India and imported Wootz steel. Around Damascus, swordsmiths learned to work with Wootz steel through processes like heat treatment, mixing, folding, annealing, and then quenching, to bring out the optimal characteristics of the steel.
The “Damascus” pattern is not what made the blades special; it was a byproduct of the material and forging techniques. Today, we can recreate this pattern and produce blades ranging from inferior to superior compared to the best Damascus blades, but this requires much more effort and is typically done by professional blade smiths.
Advantages and Disadvantages of Traditional Damascus Steel
Advantages:
- Superior sharpness and edge retention compared to other blades of its time.
- Distinctive watered pattern that is visually appealing.
- Flexibility and ability to maintain shape even after bending, making it useful for various applications such as swords and knives.
- Higher carbon content and purity than many other steels of its time, giving it an advantage in strength and durability.
Disadvantages:
- Inconsistent quality due to the lack of standardization and quality control in the production process.
- Limited quantity available globally, leading to high demand and rarity, driving up prices.
What is Modern Damascus Steel?
Modern Damascus steel is quite different. What made Wootz blades superior was their uniformity: the chemical consistency of the blade from one point to another. Wootz achieved this by almost melting the steel, allowing the environment and time to do the work for you.
Modern Damascus is made by layering steels with alternating compositions to achieve consistent properties. This process is called pattern welding. Modern Damascus can be tailored to specific needs by choosing different types of steel, whereas traditional Damascus had properties dependent on the original Wootz steel composition and forging process.

This is the method the Japanese use to create their blades. When iron is melted, it is a very non-uniform mass of material in terms of composition. The Japanese knew this and separated all the soft material from the hard material, pattern welding each type from a set of non-uniform pieces into a uniform bar. The soft material was used for the core and the hard material for the edge. Metallurgically, this was far superior to many other blades of that time. However, the pattern welding process to achieve uniformity was not limited to Japan: the Chinese, Celts, and Vikings all used this process to some extent, just at slightly different times in history.
Advantages and Disadvantages of Modern Damascus Steel
Advantages:
- Visually appealing patterns and designs due to the layering of different steels.
- Can be customized with various combinations of steels, allowing for flexibility in creating different hardness levels and characteristics.
- Similar performance to traditional Damascus steel, but often with better consistency and quality control.
Disadvantages:
- Can be more expensive than other types of steel due to the additional time and effort required in the production process.
- Not significantly better in performance compared to other high-quality steels, making it mainly a preference for aesthetic purposes.
Traditional Damascus Steel vs. Carbon Steel
In reality, traditional Damascus steel (also known as Wootz steel) is completely different in composition from modern Damascus steel.
Not all Damascus swords were exceptional. The quality of Wootz steel was inconsistent, and standardization and quality control were issues. Swordsmiths had to experiment in practice to determine if a blade was good or mediocre. The best swords were often used by Arab leaders and became famous.
European blades at the time were generally of lower quality, containing many impurities and lacking sharpness, but there were exceptions like the Ulfberht swords, which could be on par with or even superior to Damascus blades. Ulfberht swords might have been made from Wootz steel, achieving a Rockwell hardness of about 50, but they lacked consistency.
Average Damascus swords had a Rockwell hardness of about 35 to 40, with the best reaching around 50. The best Ulfberht swords had similar hardness. However, in both cases, hardness was not consistent throughout different parts of the same blade. Compared to the average European blade at that time, which had a hardness of about 25, Damascus blades were indeed special. However, modern kitchen knives have Rockwell hardness ratings ranging from 54 to 64, far surpassing ancient Damascus blades.
Modern Damascus Steel vs. Carbon Steel
From a performance standpoint, there isn’t a significant difference between modern Damascus steel and carbon steel, particularly when comparing identical knives side-by-side.
Durability:
There is no difference in durability (resistance to breaking) between Damascus steel blades and monosteel blades. Many smiths from the American Bladesmith Society (ABS) have conducted Charpy tests on their Damascus steel and found that the toughness values are equivalent to those of mono steel blades. This is because good Damascus steel is made using very similar steels with similar properties.
For example, when using 1080 and 15N20 steels, the main differences are 2% nickel and 0.10% carbon in 15N20. When enough layers are forge-welded together, the carbon content balances out, and the 2% nickel actually makes the blade tougher.
Corrosion Resistance:
Damascus steel might appear to stay cleaner, but this is due to the pattern and the number of layers. The contrasting lines in the Damascus pattern are created by etching the steel. The 2% nickel in 15N20 makes it more corrosion-resistant, so it doesn’t turn black during the etching process. The etching eats away at the 1080 steel, creating ridges where 15N20 is the peak and 1080 is the trough.
When you clean the knife, you polish the 15N20 ridges, maintaining the appearance. Personally, I don’t mind a bit of rust on my blades and haven’t found a significant difference in corrosion resistance. Follow these best practices for maintaining Damascus steel to ensure long-lasting performance and beauty.

Edge Retention:
You might notice that Damascus steel seems to stay sharper longer. Some ABS master smiths suggest that as the layers wear down, they do so at slightly different rates, creating a toothy, saw-like edge over time.
However, I haven’t paid close attention to this, or the difference is small enough that it doesn’t really matter.
Damascus Steel vs. Carbon Steel: What’s Better?
Like most questions about “which steel is better,” I have to respond with another question: “Better for what purpose?”
A good modern high-carbon steel can be just as good, if not better, than a mid-quality “Damascus” stamped steel or a 1000-year-old handmade steel forged from low-quality iron ore that a particular blacksmith had to work with.
However, a well-made Damascus steel, crafted from modern alloy steels, can outperform a mid-quality stamped carbon steel knife produced somewhere in Asia.
Choosing the best Japanese kitchen knives set for home chefs involves deciding whether Damascus steel’s craftsmanship or carbon steel’s practicality best suits your cooking needs.
But I will make a comparison to help you determine which might be better suited for different applications:
| Features | Damascus Steel | High-Carbon Steel |
|---|---|---|
| Sharpness | Excellent | Excellent (might have a slight edge) |
| Ease of Maintenance | Damascus steel generally requires less maintenance but can still benefit from oiling. | Carbon steel is prone to rust and requires regular oiling. While it can rust if not cared for properly, it is usually easier to sharpen and maintain a sharp edge. |
