Silver steel #3

Silver No.3 (Hitachi Metals Ltd.) is a very fine-grained Stainless Steel that can attain edge sharpness and edge retention comparable to some High Carbon Steels. It has even been used to create corrosion-resistant versions of Japanese traditional single bevel knives. It is very popular with both professionals and home cooks and is generally believed to be slightly easier to sharpen than VG10.
