CPM-20CV is a high-performance stainless steel developed by Crucible Industries, a leading manufacturer of specialty metals. It belongs to the family of powder metallurgy (PM) steels, which means it is made using a complex process that results in a more uniform and refined microstructure.
The main selling points of CPM-20CV are its excellent edge retention, high corrosion resistance, and toughness. It is considered to be one of the best knife steels available for high-end folders and fixed blades, and is often c. . . Show More >
CPM-20CV is a high-performance stainless steel developed by Crucible Industries, a leading manufacturer of specialty metals. It belongs to the family of powder metallurgy (PM) steels, which means it is made using a complex process that results in a more uniform and refined microstructure.
The main selling points of CPM-20CV are its excellent edge retention, high corrosion resistance, and toughness. It is considered to be one of the best knife steels available for high-end folders and fixed blades, and is often compared to other premium steels like S30V and S35VN.
CPM-20CV has a high concentration of vanadium and chromium, which contribute to its hardness, wear resistance, and corrosion resistance. It also contains a significant amount of carbon, which enables it to hold a sharp edge for longer periods of time.
However, the high hardness of CPM-20CV can make it challenging to sharpen, especially for beginners. It requires high-quality sharpening tools and techniques, such as diamond stones or ceramic rods, to maintain its sharpness.
