Sliver No.3 Stainless Steel
Sliver 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.

For knives, mirror finishing not only can enhance appearance but also can increase sharpness and durability.

Its blade is made through Honyaki process, so the edge gets very hard and retains its sharpness for a long time.

The honyaki knives cannot be mass-produced. They are primarily for professional chefs and for the most important person because of the highest quality traditional-style Japanese knives.
