S110V is a high alloy corrosion resistant stainless tool steel manufactured by Crucible Industries, an American company. Known for its remarkably high wear resistance, it’s often used in high-end pocket knives and EDC tools. It contains a high amount of vanadium carbide, which provides the wear resistance, but also makes the knife harder to sharpen. S110V has an excellent balance of good corrosion resistance and excellent wear resistance.

What are the Benefits of S110V?

The main attraction of CPM-S110V blade steel is its unparalleled level of wear resistance, which makes it an excellent choice for EDC knives that see a lot of heavy use. The high vanadium and niobium content in its composition contribute to its durability and ability to maintain a sharp edge for extended periods. Despite its hardness, S110V steel demonstrates superior toughness when correctly heat-treated—substantially reducing the risk of chipping during rigorous tasks.

Besides, its high chromium content endows it with impressive corrosion resistance making it suitable for use in various environments.

Disadvantages of S110V for Knives

One main drawback of S110V is the difficulty in sharpening. It requires specific tools and skills to sharpen and may not be a good choice for new knife owners who aren’t experienced with knife maintenance.

Additionally, it tends to be more expensive compared to other steels due to the high amounts of premium materials in its composition. Therefore, it is more commonly found in higher-end or premium knives.

Steel Rating

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

Edge Retention

6/6 Points

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


3/6 Points

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

Corrosion Resistance

4/6 Points

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


1/6 Points

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


1/6 Points

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


63 - 64 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.

How Rust Resistant is S110V?

With high chromium content of 15.25%, S110V blade steel exhibits excellent corrosion resistance. It can be used in humid, wet, and salty environments without fear of rusting or corroding. However, with any steel, proper care and maintenance is necessary to keep it in top shape.

How Strong is S110V?

The S110V knife is incredibly hard with a Rockwell Hardness rating between 63-64. This characteristic results from the high volume of vanadium carbides in its composition. The hardness benefits users in terms of superior edge retention and wear resistance but makes sharpening more challenging.

For what is S110V known for?

S110V steel enjoys a lofty reputation in the knife community for its exceptional hardness and wear resistance. It sought-after in the manufacturing of high-end pocket knives, EDC knives, and luxury cutlery. It’s appreciated for its ability to maintain sharpness even after extensive use, making it a good option for those who demand performance from their blades.
