When it comes to choosing the right Japanese kitchen knife, one of the most important factors is the type of steel used in the blade. Among the most popular choices in modern Japanese cutlery are VG10 and AUS10 stainless steels. Both are highly respected, but they serve slightly different purposes depending on your needs.
Let’s break them down so you can decide which steel is right for your cutting style.
