CPM-20CV is a top-quality stainless steel that is comparable to Bohler M390 and CTS-204P. It is made using powder metallurgy, which results in a high carbide content. This steel offers excellent edge retention and corrosion resistance, while still being relatively easy to sharpen. It is a popular choice for both high-end production knives and custom-made ones. However, it is worth noting that the high carbide volume and coarse microstructure of this steel make it slightly less tough.
