Thank you for viewing. Introducing a natural whetstone from Kyoto Shobonzan. I received this old Nakayama whetstone from a member of the cooperative. Despite its hard surface, it has fine and strong abrasive power, a top-quality item. Size: 134mm x 62mm x 14mm, 398g Thank you very much. ※ Received directly from a member of a whetstone shop cooperative in Kyoto. Please be aware of accounts selling stolen goods by foreigners.
