CTS-BDZ1 is a budget-friendly stainless knife steel produced by Carpenter Technology Corporation based in the United States. Known primarily for its excellent corrosion resistance, this steel has good edge retention and sharpening abilities which make it an attractive option for everyday carry (EDC) knives. While it doesn’t command the respect of high-end knife steels, CTS-BDZ1 holds its own in the budget steel category, providing a balance of performance for cost.

What are the Benefits of CTS-BDZ1?

CTS-BDZ1 provides an impressive balance between cost and performance. As a stainless steel, it has excellent corrosion resistance, making it a solid choice for knives that may be exposed to moisture or humid environments. The steel's good edge retention and ease of sharpening also make it a popular choice in the market for everyday carry knives.
Furthermore, its hardness rating of '56-60 HRC' contributes to its longevity, durability and adaptability in various tasks.

The affordability of CTS-BDZ1 is also a significant advantage, especially for those seeking a reliable knife steel without breaking the bank.

Disadvantages of CTS-BDZ1 for Knives

While CTS-BDZ1 is an excellent budget steel, it doesn't quite match up to the performance of premium knife steels. The edge retention and overall durability are decent, though not exceptional when compared with high-end steels.
Another drawback is that despite its relatively good hardness, CTS-BDZ1 can still be prone to deformation under heavy use.

Steel Rating

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

Edge Retention

3/6 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

5/6 Points

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


4/6 Points

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


5/6 Points

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


56 - 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.

How Rust Resistant is CTS-BDZ1?

One of the key strengths of CTS-BDZ1 is its excellent corrosion resistance. Thanks to the 16% chromium content, this steel is highly resistant to oxidation and rust, making it suitable for usage in humid and wet conditions.

How Strong is CTS-BDZ1?

The hardness rating for CTS-BDZ1 ranges from 56 to 60 HRC. This range provides the steel with a good balance of edge retention and durability without sacrificing too much toughness.
The hardness in CTS-BDZ1 contributes to its ability to maintain a sharp edge for an impressive length of time before needing to be resharpened.

For what is CTS-BDZ1 known for?

CTS-BDZ1 holds a solid reputation as a budget-friendly stainless knife steel. It's known as an excellent stainless steel material for everyday carry knives that offers a good balance between cost and performance, especially in regards to its rust resistance and decent edge retention.


In conclusion, CTS-BDZ1 is an impressive budget-friendly knife steel that offers a great balance of features. With its excellent rust resistance, sufficient hardness, and overall decent performance, it's an ideal choice for those in need of a reliable, affordable blade steel for their EDC knives. While it might not have the supreme performance of premium steels, for its price point, CTS-BDZ1 is undeniably a strong competitor in the market.
