Houchou-Dotcom Whetstone Coarse Grit "Jinzou Omura Whetstone" Blue/Gray 210x80x50mm

Omura whetstone (natural) is a natural whetstone produced in Omura City, Nagasaki Prefecture. Due to its strong resemblance, the Mesuki whetstone produced in Wakayama Prefecture also came to be called Omura whetstone. Currently, production has ceased in both Nagasaki and Wakayama. Although it is a coarse whetstone, it is slightly soft and has long been favored by knife-making artisans, but production stopped about 10 years ago. Now, Omura whetstone has become a valuable natural coarse whetstone, and artificial Omura whetstone has been manufactured at the suggestion of an artificial whetstone manufacturing company.
