Tsukinowa Awasedo Hon-Suita Hard Grade 2, 40-cut Dimensions: Length 205mm, Width 83mm, Thickness 45mm Weight: 1907g Grain Size: Finishing (8000#↑) Hardness (Soft 1-10 Hard): 9 Uses: Japanese kitchen knives, carpentry tools, final finishing of swords Tsukinowa Awasedo is a whetstone mined within the grounds of Tsukinowa Temple, located 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 mountain owner, we are mining to support the restoration efforts. The sales proceeds are donated for the repair of the temple. Thank you for your support. Available for immediate purchase.
