CPM-154 is a knife steel made in USA by Crucible, known to offer superior edge retention and toughness. This is a premium, high-quality stainless steel, touted specifically for its use in professional-grade EDC knives and survival tools. It has excellent working properties, making it a preferred choice for many knife manufacturers.

Advantages of CPM-154 as Knife Steel

CPM-154 is a high-quality knife steel that offers great benefits for EDC knives, such as superior edge retention and excellent toughness. It also provides a smooth surface finish, remains sharp for prolonged periods, and is easy to maintain and sharpen. It has a higher alloy modulus than other steel, providing a better overall wear resistance and making it a top choice for professional-grade knives.

Disadvantages of CPM-154 for Knives

The only disadvantage of CPM-154 is that it is on the expensive side, reflecting the high quality of this knife steel. You might also require professional sharpening tools to maintain its edge.

Steel Rating

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

Edge Retention

4/6 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


3/6 Points

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


4/6 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 CPM-154 Rust Resistant?

Another great feature of CPM-154 knife steel is its excellent corrosion resistance. This is due to its high chromium content, which offers a strong defense against rust. This rust resistance makes it ideal for outdoor and marine applications.

How Durable is CPM-154?

CPM-154 has a hardness range of 58 - 60 HRC, making it a highly durable knife steel. The high hardness level ensures the knives' sharpness and strength are retained longer than many other steels, making it perfect for high-endurance tasks.


CPM-154 has a solid reputation for being among the top-performing knife steels available today. It is typically found in premium quality EDC knives, chef's knives and all manner of professional tools.


In conclusion, while CPM-154 knife steel may be considered expensive, it offers high enduring value. It strikes a reliable balance between hardness, toughness, and corrosion resistance. The ease of maintenance and lasting sharpness make it well worth the investment for any serious knife user or collector.
