A Santoku is a medium-sized, multipurpose kitchen knife of Japanese origin that has a lightweight blade with a straight or slightly curved cutting edge and a spine that curves downward to the tip. The santoku has long been the Japanese equivalent of a chef’s knife. Compared with a classic chef’s knife, the santoku is typically shorter and has a thinner blade, a stubbier tip, and a straighter edge.
VG-10 is one of the most popular stainless steels amongst Japanese knife makers. It has good edge retention and is very wear and corrosion resistant. Shun is one of the more famous companies also using this steel in their production lines.
