Tsukinowa Awasedo Uchigumori Akarenge Medium Hard, Flawless, Extremely Fine, 24-cut Dimensions: Length 221mm, Width 82mm, Thickness 15mm Weight: 558g Grain Size: Finishing (8000#↑) Hardness (Soft 1-10 Hard): 6 Uses: Japanese knives, carpentry tools, final polishing of swords Tsukinowa Awasedo is a whetstone mined within the grounds of Tsukinowa Temple, near Mt. Atago in Kyoto. Depending on the school, it is a whetstone used for the final polishing of swords. It combines the characteristics of both East and West whetstones, and I believe it can be used for various blades. Please give it a try. Due to a disaster several years ago, many cultural assets within the temple grounds of Tsukinowa Temple were damaged. Currently, with the permission of the temple owner, we are excavating to support the restoration efforts. The proceeds from sales are donated to the temple for repairs. Thank you for your support. Available for immediate purchase.
