Stainless Steel vs. Carbon Steel
When selecting the ideal Japanese knife, the type of steel plays a huge role in its performance. This guide will break down the main differences between carbon and stainless steel knives, and explain why carbon steel is a top choice for many serious home cooks as carbon steel knives are favored by professional chefs because they hold a sharp edge for much longer, making them perfect for those who use their knives regularly!

Steel Types Overview
- Carbon Steel: Preferred by professionals, carbon steel knives are prized for their razor-sharp edge and long-lasting sharpness. However, they require more diligent care, as they are more prone to rust and discoloration without proper maintenance.
- Stainless Steel: While stainless steel knives are a go-to for home cooks due to their rust resistance and easy upkeep, their high chromium content makes them durable but less sharp compared to carbon steel.
Carbon Steel Type |
Description |
Blue Steel #1 |
Blue Steel #1 has superior edge retention, contributing to the overall strength of the blade. What is Blue Steel #1 made of? Blue Steel #1 is similar to Blue Steel #2 but contains higher amounts of carbon and tungsten, which enhances its hardness and edge retention. |
Blue Steel #2 |
Because of the way it is forged, Blue Steel #2 has extra materials that make the steel tough, and help it hold a sharp edge. |
Aogami Super |
Aogami-Super is considered one of the top Japanese carbon steels. |
White Steel #1 |
White Steel #1 is highly favored by professional chefs who specialize in traditional Japanese cuisine. Its ability to be sharpened to an extremely fine edge, combined with excellent edge retention and ease of re-sharpening, makes it a popular choice. What is White Steel #1 made of? White Steel #1 is an upgraded version of White Steel #2, with added carbon for extra hardness. |
White Steel #2 |
White Steel #2 is a great choice for those new to Japanese traditional knives, and it is known for having minimal impurities as well as a fine grain structure. This makes it ideal for high-quality cutting tools like traditional Japanese knives. Even though it is considered a basic carbon steel, it offers excellent edge retention and is easy to re-sharpen. |

Key Characteristics to Consider
-
Hardness
Hardness, measured on the Rockwell Scale (HRC), determines how often a knife needs sharpening and its overall durability. Carbon steel knives typically have a higher HRC, which means they can maintain a sharp edge for longer and offer a more efficient cutting experience. However, the trade-off is that higher hardness makes the knife more brittle and prone to chipping.
Why does high HRC lead to chipping? A higher HRC means the steel is harder but also less tough, making it more susceptible to breaking or chipping. This is why carbon steel knives need to be handled carefully and used on a soft cutting surface to prevent damage.
Top three carbon steels with the highest HRC are:
1. Aogami Super (64-67 HRC)
2. Blue Steel #1 (63-65 HRC)
3. White Steel #1 (63-65 HRC)
-
Rust Resistance
Stainless steel knives have better rust resistance compared to carbon steel due to their higher chromium content. However, if you prefer the sharpness of carbon steel, you’ll need to take extra steps to prevent rust. Using protective oils or rust erasers can help maintain the blade’s condition.
Top three carbon steels with the best rust resistance are:
1. Aogami-Super (Cr 0.3-0.5%)
2. Blue Steel #1 ( Cr 0.3-0.5%)
3. Blue Steel #2 ( Cr 0.2-0.5%)
-
Ease of Sharpening
Carbon steel is generally easier to sharpen than stainless steel. This is because stainless steel is tougher, which makes it harder for sharpening stones to grip the edge properly, whereas carbon steel sharpens more easily and smoothly.
Why is carbon steel easier to sharpen? Stainless steel's toughness makes it harder for the sharpening stone to bite into the blade, so sharpening takes more effort. Carbon steel, on the other hand, responds better to sharpening stones, making it easier to achieve a razor-sharp edge.
Top three carbon steels that are easiest to sharpen* are:
1. White Steel #1 (★★★★★)
2. White Steel #2 (★★★★★)
3. Blue Steel #1 (★★★★)
Why should you choose a Carbon Steel Japanese Knife?
Everyone admires carbon steel knives, but many aren’t sure what makes them so special beyond their impressive appearance. The real appeal lies in the blade itself. Carbon steel blades are harder than typical stainless steel options, allowing them to achieve and maintain an exceptionally sharp edge when properly sharpened. This makes them highly effective for those who use their knives frequently.
Is a carbon steel Japanese knife worth it? Carbon steel can be up to 20% stronger than mild steel, making it a fantastic choice for applications requiring high strength and hardness. However, this strength also means that carbon steel knives can be more expensive, which is often a concern for many buyers. The higher cost is due to the material’s superior performance and durability, which drives up the price of tools made from it.
Ultimately, whether a carbon steel knife is worth the investment depends on your personal needs, preferences, and budget. We highly recommend carbon steel knives for professional chefs who need a reliable and razor-sharp tool for long cooking sessions. For intermediate home cooks, a carbon steel knife can be a beautiful upgrade, but it comes with the responsibility of more frequent maintenance, including honing and sharpening. If you’re ready to take on that extra care, a carbon steel knife can be a valuable and impressive addition to your kitchen.
Benefits of a carbon steel knife
For those considering a carbon steel knife, you should note the following key characteristics:
-
Strength and hardness: Carbon steel knives are known for their hardness reaching HRC levels of 67 and above, making them ideal for regular use in the kitchen. They can also maintain this sharp edge for longer than many other types of knives.
Additionally, with a carbon steel knife, a smaller sharpening angle means you need less force to cut, which delays the onset of fatigue. This is a big plus for professional chefs who spend hours preparing food every day!
-
Cost-effective: Even though a carbon steel knife might cost more at first, its durability makes it a smart investment. These knives are built to last, so they can save you money in the long run.
With the right care, a high-quality Japanese knife, especially those made from carbon steel, can last a lifetime. This means you won’t need to replace it often.
- Superior edge retention: Carbon steel knives are known for their exceptional ability to hold a sharp edge. This means they stay sharp longer compared to many other types of knives, reducing the need for frequent sharpening. Their hard, fine grain structure allows them to cut with precision and maintain a razor-sharp edge, which is especially valuable for tasks that require a lot of slicing and chopping.
