These Tokyuju Koma Nagura are extremely rare, especially in this format. They are traditionally used for sword polishing. These examples contain black dots which can scratch the steel but upon extensive testing, they are not an issue and no scratching of the soft\/hard steel occured. Compared directly to the polishing results of the Botan and Tenjou which we received, these Koma Nagura exhibit a high level of refinement, consistent with their traditional classification. When sharpening a vintage plane blade, this Nagura cuts the steel very quickly with semi dry but extremely smooth feedback. \u003c\/span\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003c\/span\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cstrong\u003eA photo of the stone's polishing ability on soft and hard steels of a Japanese kanna (plane) blade are shown.\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Griffith Shaving Goods","offers":[{"title":"Default Title","offer_id":41822675271774,"sku":"2024","price":520.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0778\/2905\/files\/IMG_3107_fc453edc-5d6a-4b50-9470-e70b6121e7e6.jpg?v=1750984466","url":"https:\/\/www.griffithshavinggoods.com\/fr\/products\/mikawa-shiro-nagura-koma-japanese-whetstone-1","provider":"Griffith Shaving Goods","version":"1.0","type":"link"}
