The CPM-20CV is a high-end powder steel from Crucible, U.S.A, known best for its exceptional edge retention and impressive corrosion resistance. It’s ideal for high-quality pocket knives, or EDC knives, and outdoor tools. As a Crucible Particle Metallurgy (CPM) manufactured product, it guarantees excellent performance and stability in an array of situations.
What are the Advantages of CPM-20CV?
The CPM-20CV offers outstanding edge retention and is considered one of the best knife steels in terms of corrosion resistance and toughness. With its CPM makeup, it ensures uniform distribution of elements, resulting in impressive wear resistance and toughness.
It is also favoured for its excellent sharpenability, a trait that makes it fit for making high-quality EDC knives.
Disadvantages of CPM-20CV for Knives
Despite all the benefits, the 20CV is quite expensive. It falls into the premium price range, which might not appeal to everyone. Additionally, while it has excellent edge retention, it can be relatively challenging to re-sharpen once it loses its edge.
