This 180mm Bunka profile combines a straighter edge with a pointed reverse tanto tip, facilitating slicing, dicing, and chopping tasks while enabling detailed work through its angled point. The blade measures 2.9mm at the heel and tapers to 0.7mm at the tip, weighing 149g with a 49mm heel height.\u003c\/p\u003e\u003cp\u003eNigara constructs this knife using sanmai stainless damascus cladding over an SLD core hardened to 62-64 HRC. This cold work die steel contains about 12% chromium, per Proterial, and forms hard carbides for edge retention, requiring drying after use to prevent rust. The blade displays a vertical Tsuchime hammer tone pattern beneath a Kurouchi etched finish. An octagonal stabilized birch burl handle provides a distinct grain texture and durable grip, completing a design that reflects Nigara’s Tsugaru sword smithing lineage and modern metalworking technology in Aomori.\u003c\/p\u003e","brand":"Hatsukokoro","offers":[{"title":"Default Title","offer_id":46243476734173,"sku":"HT-YROSLDCTDS-BK165BR","price":671.98,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0287\/7227\/0217\/files\/HatsukokoroxNigaraYorokobiSLDCopperHammeredDamascusBunka180mmBirchHandle-20250228-12.jpg?v=1741063119","url":"https:\/\/www.knivesandstones.com.au\/products\/hatsukokoro-x-nigara-yorokobi-sld-copper-tsuchime-damascus-bunka-180mm-birch-handle","provider":"Knives and Stones","version":"1.0","type":"link"}
