CPM 154CM Stainless Steel for Knife Blades

Crucible CPM 154CM Stainless Steel

Manufacturer: Crucible

CPM 154CM is a popular cutlery steel from Crucible, that offers good value and machinability and still outperforms 440C in nearly every way. 154CM is one of the workhorses of the high-end sporting knife industry, considered to be one of the benchmark steels to all others are compared. It is also one of the most common premium steels and has become more affordable in recent years.

154CM displaced ATS-34 as the premium steel of choice in the late 90's, and has been very popular ever since. 154CM is actually nearly identical to ATS-34, which has since become less popular due to increase availability of 154CM, which is an American product. Crucible's particle metallurgy process also produces a product with a more uniform microstructure, resulting in a more reliable steel with a finer edge less prone to chipping.

Just about every premium knife company has used 154CM, but Benchmade does use it extensively as well as Zero Tolerance in their lower-end models. Their higher-end models use S30V, which is the current all-purpose super steel.
