12c27 Steel vs 420HC – What’s the Difference

12c27 Steel vs 420HC

If you are a knife collector or simply an enthusiast, you know that the type of Steel used in your blade can make all the difference. Every Steel has unique properties, and selecting the right one for your needs is vital. Two popular steel sheets chosen by many knife makers are 12c27 and 420HC. These steels are known for their durability and sharpness, making them great for practical use. But which one is better? This article will compare and contrast these two steels and help you decide which is best suited for your needs.

What is 12c27 Steel?

12c27 is a stainless steel manufactured by Sandvik. It is popular among knife makers because of its superior strength, corrosion resistance, and ease of sharpening. This Steel has a high carbon content, which makes it highly durable and able to hold an edge for a longer time. Knives made with 12c27 are ideal for heavy-duty usages, such as hunting or camping trips, where you need a sharp edge that can withstand tough conditions. However, the high carbon content in this Steel means it is more brittle and hard to sharpen than 420HC.

What is 420HC Steel?

420HC is part of the 400 series of stainless Steel. This Steel is more affordable and readily available, making it an excellent choice for knife makers who want to save money on materials. 420HC is known for its excellent corrosion resistance, making it an ideal choice for knives in wet or humid conditions. This Steel is also easier to sharpen than 12c27, making it an excellent choice for those who prefer double-bevelled knives. However, 420HC is softer than 12c27, meaning it will quickly lose its edge.

Difference Between 12c27 Steel and 420HC

Blade Performance

When it comes to blade performance, 12c27 Steel is undoubtedly the winner. It is more durable and can hold an edge for a longer time. Its high carbon content makes it better suited for heavy-duty usage, such as chopping and slicing. On the other hand, 420HC Steel may not be as durable as 12c27, but it is more flexible and can withstand bending or flexing without breaking. Additionally, it is easier to sharpen than 12c27.

Corrosion Resistance

The corrosion resistance of a knife blade is an essential factor to consider, especially if you plan to use your knife in wet or humid conditions. Both 12c27 and 420HC steels have excellent corrosion resistance, making them a great choice for outdoor activities. However, 12c27 Steel has better corrosion resistance than 420HC Steel, making it better suited for marine environments.


In summary, 12c27 and 420HC are excellent steel choices for knife making, depending on your needs and preferences. 12c27 is more durable, corrosion-resistant, and able to hold an edge for longer, making it an excellent choice for heavy-duty usage. Meanwhile, 420HC is more flexible, easier to sharpen, and available at a more affordable price, making it ideal for everyday use. Ultimately it comes down to personal preferences and what task you need your knife for. So, take the time to consider your needs and choose the right Steel for your blade.
