The twisted-grain Damascus steel is built through a layered marriage of multiple steels, folded and torqued at the forge until the grain corkscrews into a signature spiral — each revolution unique, each blade a one-off that no craftsman could reproduce exactly. Torch it purple and the pattern deepens, the violet-baked finish sinking into every twist and fold like ink into paper.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe edge lands at 60 HRC — hard enough to hold its bite, but backed by the composite give of Damascus construction so it won't shatter under stress. In hand, the taper tells the rest of the story: 3.2 cm at the habaki, narrowing to 2.6 cm toward the kissaki, driving the balance point back toward the grip where it belongs.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eImported ebony for both tsuka and saya — dense, dark, cool to the touch, a wood that has meant seriousness in Japanese bladesmithing for centuries. Copper fittings bridge the transitions with warmth against all that darkness. At just under 1.4 kilograms, the weight lands where tradition says it should: heavy enough to feel, light enough to forget.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-pre-wrap leading-[1.7]\"\u003eOverall Length: 103 cm (40.6 in)\u003cbr\u003eBlade Length: 73 cm (28.7 in)\u003cbr\u003eHandle Length: 26 cm (10.2 in)\u003cbr\u003eBlade Width: 3.2 cm → 2.6 cm (1.26 in → 1.02 in)\u003cbr\u003eBlade Thickness: 0.75 cm (0.30 in)\u003cbr\u003eWeight: Approx. 1.4 kg (2.8 jin \/ 3.1 lb)\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-pre-wrap leading-[1.7]\"\u003eBlade: Pattern-welded Damascus steel, twisted-grain forging, purple-baked finish\u003cbr\u003eTsuka \u0026amp; Saya: Imported ebony\u003cbr\u003eFittings: Copper\u003c\/p\u003e","brand":"Sword Age Forge","offers":[{"title":"Hand Sharpened \/ No thanks","offer_id":46714065060001,"sku":null,"price":499.0,"currency_code":"USD","in_stock":true},{"title":"Hand Sharpened \/ Engrave it!","offer_id":46714065092769,"sku":null,"price":499.0,"currency_code":"USD","in_stock":true},{"title":"Unsharpened \/ No thanks","offer_id":46714065125537,"sku":null,"price":499.0,"currency_code":"USD","in_stock":true},{"title":"Unsharpened \/ Engrave it!","offer_id":46714065158305,"sku":null,"price":499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0713\/2112\/5025\/files\/01_33b9564c-3b8f-4a6e-8aa8-b04a91eb2edc.jpg?v=1784359191","url":"https:\/\/swordageforge.com\/products\/twist-pattern-welded-steel-katana-%e3%83%91%e3%83%bc%e3%83%97%e3%83%ab%e3%82%b5%e3%83%b3%e3%83%80%e3%83%bc","provider":"Sword Age Forge","version":"1.0","type":"link"}
