This mirrors the differential heat-treatment of a traditional Japanese katana. The distinctive wavy clad line where soft outer iron meets the hard carbon steel core is a hallmark of this steel, and the 登録 (Tōroku) registered stamp confirms authenticity. The lightweight magnolia handle keeps the balance tip-forward for effortless vegetable and protein work.\u003c\/p\u003e\u003ch2\u003eCare \u0026amp; Maintenance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHand wash only - never dishwasher\u003c\/li\u003e\n\u003cli\u003eDry immediately after use to prevent oxidation\u003c\/li\u003e\n\u003cli\u003eHone regularly on a whetstone\u003c\/li\u003e\n\u003cli\u003eSharpen on Japanese water stones (1000\/3000 grit)\u003c\/li\u003e\n\u003cli\u003eStore on a magnetic rack or in a knife roll - never loose in a drawer\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Chef \u0026 a Knife","offers":[{"title":"Default Title","offer_id":55578845905187,"sku":"2275","price":80.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0261\/1819\/3230\/files\/20A1F5B2-2170-44D0-A895-9157BFEE585C.jpg?v=1789357668","url":"https:\/\/chefandaknife.com.au\/products\/vintage-katsuhiro-santoku-knife-170mm-high-carbon-steel-magnolia-handle-2275","provider":"Chef \u0026 a knife","version":"1.0","type":"link"}
