blead knife is called Pankiri in Japan. Pankiri is for cutting bread or cake and has a serrated edge. Due to its serrated profile, the actual edge does not hit against the cutting board, thus it can hold its edge relatively long.
It is difficult to sharpen Pankiri at home, but since it is not meant to cut anything hard, it can be used for a long period of time.
