Knife Blade Materials

A look at the different Knife Blade Materials and why exactly these materials are used.

 

The Ideal knife blade would stay sharp throughout sustained use, sharpen easily and resist corrosion. However, there are some trade offs that you need to consider. Harder steel will hold a better edge and it is less resistant to becoming rusty, but it is far more difficult to sharpen. Softer steel on the other hand won’t rust as easily, is easier to sharpen, but it doesn’t stay sharp for very long.

 

Stainless Steel Knife Blade Material

Stainless steel is an alloy that resists rust and corrosion and most blades are made of this material. There are three popular examples of stainless steel that is used in the making of knife blades:

 

420HC: This is an affordable stainless steel that resists corrosion, has fair edge retention, and it sharpens quite easily.

154CM: This stainless steel is of a higher grade and contains more carbon to make it harder and maintains good edge retention.

S30V: This type of stainless steel contains a high amount of vanadium which is a rust resistant carbide which adds greater wear resistance and toughness to the blade. This also has superior edge retention.

 

 

High-Carbon Steel Knife Blade Material

You do find some knifes as well that are made of non stainless high carbon steel. They are perfect for a harder blades and edge retention. However, they are much more likely to corrode than stainless steel blades are.

 

Now that you know all about the different blade materials the next step is to learn how to keep these blades as sharp as possible for optimal use.
