Hardened to approximately 65–67 HRC, it delivers exceptional edge retention and the ability to hold an extremely fine cutting edge for an extended period, which is why it has become one of the most sought-after steels among professionals and serious enthusiasts.\u003c\/p\u003e\n\u003cp data-end=\"1815\" data-start=\"1424\"\u003eWith its very high carbon and chromium content, ZDP-189 combines extreme hardness with good corrosion resistance, allowing the edge to last far longer than most conventional kitchen knife steels. This level of performance greatly reduces the need for frequent sharpening, though the same hardness means ZDP-189 requires more skill and proper equipment if sharpening or edge repair is needed.\u003c\/p\u003e\n\u003cp data-end=\"2174\" data-start=\"1817\"\u003eDue to its cost and demanding production process, ZDP-189 is typically reserved for top-tier knives and is most often used as a hardened core in laminated (San Mai) constructions. Cladding the core with softer stainless steel adds toughness and ease of maintenance while preserving the outstanding cutting performance and edge retention that define ZDP-189.\u003c\/p\u003e\n\u003cdiv id=\"specs\" class=\"tab-content\"\u003e\n\u003ch2\u003eKnife Specs:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHRC:\u003c\/strong\u003e 66-67\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade:\u003c\/strong\u003e Hayate Suminagashi ZDP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStain Resistant:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Material:\u003c\/strong\u003e ZDP-189 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEdge Angle:\u003c\/strong\u003e Double Edged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Material:\u003c\/strong\u003eStabilized Maple Burl Handle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolster Material:\u003c\/strong\u003eAlternative Ivory Bolster\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Shape:\u003c\/strong\u003e Octagonal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSaya Cover:\u003c\/strong\u003eMagnetic Oak Saya Cover\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Yoshihiro Cutlery","offers":[{"title":"8.25\" (210mm)","offer_id":47530991780070,"sku":"SZDPSMKI210IVBMO","price":679.99,"currency_code":"USD","in_stock":true},{"title":"9.5\" (240mm)","offer_id":47530997645542,"sku":"SZDPSMKI240IVBMO","price":719.99,"currency_code":"USD","in_stock":true},{"title":"10.5\" (270mm)","offer_id":47530997678310,"sku":"SZDPSMKI270IVBMO","price":799.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0505\/4778\/5915\/files\/SZDPSMKIIVBMO_PT01.jpg?v=1775859704","url":"https:\/\/echefknifv.com\/products\/hayate-sukenari-zdp-189-super-high-carbon-stainless-steel-damascus-kiritsuke-chef-knife-octagonal-handle-with-alternative-ivory-bolster","provider":"Yoshihiro Cutlery","version":"1.0","type":"link"}
