Fuji Hamon","description":"\u003cp\u003eThis Genkai Masakuni Mizu-Honyaki Maguro Kiri is a 450mm single-bevel tuna slicer forged from White 2 steel, featuring a Mt. Fuji hamon and best fitting professional chefs requiring extended blade length for large fish preparation. Master Mukou Yoneo produces this mizu-honyaki construction using a technique with a high failure rate due to concentrated stress at the pattern peak, resulting in a mirror-polished blade that measures 434mm in edge length and weighs 445g.\u003c\/p\u003e\u003cp\u003eThe White 2 carbon steel blade has a hardness between 60 and 64 HRC and requires immediate wiping and drying after use to prevent corrosion. This reactive honyaki construction lacks stainless cladding and demands meticulous maintenance alongside regular sharpening to preserve the cutting edge. The spine measures 4.6mm at the heel, tapering to 2.2mm at the tip with a 42mm heel height, providing the geometry necessary for precise slicing tasks.\u003c\/p\u003e\u003cp\u003eGenkai Masakuni knives are among the most collectible in the industry, representing decades of craftsmanship from a maker who trained in Sakai before establishing his forge on Kabe island near Karatsu. As one of few blacksmiths capable of consistently producing the Mt. Fuji hamon, Mukou Yoneo applies this rare honyaki method specifically to White 2 steel, creating a specialised tool defined by its distinct temper line and traditional manufacturing origin.\u003c\/p\u003e","brand":"Genkai Masakuni","offers":[{"title":"Default Title","offer_id":46826543120605,"sku":null,"price":8149000.0,"currency_code":"KRW","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0287\/7227\/0217\/files\/DSC_5863.jpg?v=1759213933","url":"https:\/\/www.knivesandstones.co.kr\/en\/products\/genkai-masakuni-%e7%8e%84%e6%b5%b7%e6%ad%a3%e5%9c%8b-honyaki-maguro-kiri-450mm-mt-fuji-hamon","provider":"Knives and Stones","version":"1.0","type":"link"}
