The HAKUTO series is recommended for those who are looking for a high level of difficulty in sharpening kitchen knives, such as Honyaki, Sanmai, and mirror-finish knives, and who are concerned about sharpening knives sharper and more beautifully.

HAKUTO 1 to 3 are available in three different softness levels to suit different blades and preferences.
Among them, HAKUTO 2 is the medium softness in the HAKUTO series. Soft HAKUTO2 with an S after the number (ex. #3000S, #6000S) is the best for mirror finishing.
