Tsukinowa Awasedo Hon-Suita Karasu Medium Hard, Extremely High-Grade Thick Stone, 24-cut Dimensions: Length 219mm, Width 95mm, Thickness 70mm Weight: 3183g Grain Size: Finishing (8000#↑) Hardness (Soft 1-10 Hard): 7 Uses: Final finishing for Japanese knives, carpentry tools, and 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 edged tools. 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, we are excavating with the permission of the mountain owner to support the restoration. The sales proceeds are donated for the repair of the temple. Thank you for your support. Available for immediate purchase.
