The blade features a mirror polish finish and measures 226mm in edge length, with spine thicknesses of 4.4mm at the heel, 3.6mm at mid, and 2.8mm at tip. Weighing 325g with a 52mm heel height, this construction represents one of the rarest techniques in Japanese knife making, produced by a maker known for Mt Fuji hamon honyaki and mizu-honyaki methods.\u003c\/p\u003e\u003cp\u003eWhite 2 carbon steel contains 1.1% carbon and registers between 60-64 HRC, offering an edge that sharpens readily while requiring immediate wiping and drying after use to prevent corrosion. As a reactive carbon steel without stainless cladding, the blade demands meticulous care including light oiling during storage. Mukou Yoneo trained in Sakai before establishing his forge on Kabe island near Karatsu, Saga Prefecture, where he continues to produce knives characterised by concentrated stress patterns at the hamon peak. This Usuba pairs these material properties with traditional geometry for precise vegetable work, reflecting decades of specialised forging expertise in a collectible format.\u003c\/p\u003e","brand":"Genkai Masakuni","offers":[{"title":"Default Title","offer_id":46973030039773,"sku":null,"price":3524000.0,"currency_code":"KRW","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0287\/7227\/0217\/files\/DSC_7618.jpg?v=1762819996","url":"https:\/\/www.knivesandstones.co.kr\/en\/products\/exotic-genkai-masakuni-%e7%8e%84%e6%b5%b7%e6%ad%a3%e5%9c%8b-white-2-honyaki-usuba-240mm-ebony-set","provider":"Knives and Stones","version":"1.0","type":"link"}
