440A vs 420HC Stainless Steel – What’s the Difference

440A vs 420HC Stainless Steel

When it comes to knives, the material it is made from is just as important as the design and craftsmanship. Two commonly used stainless steels for making knife blades are 440A and 420HC. If you’re wondering about the differences between these two types of steel, you’ve come to the right place. In this blog post, we’ll review the contrasts between 440A and 420HC stainless steel and which might be better for your intended use.

Difference Between 440A and 420HC Stainless Steel


The first difference between the two materials is their composition. 420HC stainless steel has a higher carbon content than 440A. The higher carbon content makes it harder and gives it better edge retention. On the other hand, 440A stainless steel has around 0.6% carbon content, which is less than 420HC. Also, 440A has higher chromium content, responsible for corrosion resistance.


440A and 420HC are tough materials, but 420HC is tougher than 440A. It means 420HC can withstand more force without damaging the blade than 440A. However, this might be an optional factor depending on its intended use.


Regarding sharpening, 420HC is easier to sharpen than 440A stainless steel. The higher carbide content in 440A requires a more professional sharpening process, which might disadvantage some knife users.


The cost of a knife made with 420HC stainless steel is generally lower than that of 440A stainless steel. Due to its exceptional corrosion resistance properties, 440A is more expensive than 420HC. Nonetheless, other factors, such as design, branding, and accessories, can also affect the cost of the blade.

Best use cases

440A stainless steel is often used in budget-friendly and low-cost knives due to its relatively low price point. It is a versatile material suitable for everyday use and light-duty outdoor activities. 420HC stainless steel, on the other hand, is a better choice for heavy-duty tasks and professional use due to its superior edge retention and toughness.


To sum up, 440A and 420HC stainless steel are good materials for knife-making, but the choice between the two depends on your intended use. If you’re looking for a budget-friendly knife for everyday use and light-duty tasks, a 440A stainless steel knife might be the best option. However, if you’re looking for a knife for heavy-duty tasks, 420HC stainless steel might be a better choice due to its superior toughness and edge retention. Understanding the differences between the two materials can help you make a more informed decision when purchasing a knife.
