D2, also known as D2 Tool Steel, has historically been used in various types of industrial applications, including as a cutting tool in various industries. Its popularity stems from its high hardness and wear resistance, which makes it suitable for making sturdy, high-quality knives. Despite its name, D2 is technically a semi-stainless steel due to its relatively high chromium content, although it lacks the corrosion resistance of true stainless steel.

Advantages of D2 as Knife Steel

When it comes to the benefits of D2 tool steel, the primary advantages are its wear resistance and durability. These characteristics make it a top pick for companies looking to produce knives that withstand heavy use without losing their edge. Another advantage of D2 steel is its affordability when compared to other high-end knife steels. It's an excellent choice for those who need a reliable knife for everyday use and are also conscious about the cost.

Disadvantages of D2 for Knives

While D2 offers a host of benefits, like most things, it also has its drawbacks. The most notable disadvantage is its relative susceptibility to corrosion, due to its status as a semi-stainless steel. It requires more care and maintenance compared to true stainless blades. Additionally, because of its hardness, D2 can be somewhat difficult to sharpen especially for beginners.

Steel Rating

Steels with good edge retention will stay sharp longer, reducing the need for frequent sharpening

Edge Retention

Toughness is the steel's ability to absorb energy and deform without breaking


4/6 Points

Corrosion Resistance measures how well the steel can resist rust and oxidation

Corrosion Resistance

1/6 Points

Sharpenability refers to how easily a knife blade can be sharpened to its desired edge


3/6 Points

This is a relative measure based on typical market values. The actual price can vary widel


3/6 Points

A higher HRC number typically indicates a harder steel, which can hold a sharper edge


58 - 60 HRC
Please be aware that this rating should be understood as a comparative measure. It's simply a rough estimation in relation to other knife steels.

Is D2 Rust Resistant?

In terms of rust resistance, D2 is considered a semi-stainless steel knife, meaning it has a better resistance to rust than some other steels, but not as good as true stainless steels. To keep a D2 knife free from rust, it is still essential to keep the blade clean and dry after every use and storing it properly.

How Durable is D2?

A D2 blade has an excellent hardness rating, typically in the range of 58-60 HRC. This high hardness allows the D2 knife blade to hold an edge exceptionally well, which makes it an excellent choice for tasks where sharpness and edge retention is paramount.


D2 steel is known for its long-term edge retention and toughness. It's widely respected within the knife-making community for these properties and is often utilized in premium-quality hunting, camping, and EDC knives. If looked after properly, a D2 knife can be a resilient and reliable tool for a wide variety of tasks.
