The hamon is an irregular wave formed by clay tempering rather than etched on afterwards, and the tip carries a true yokote — a real geometric transition rather than a polished line.\u003c\/p\u003e\n\u003cp\u003eFittings are gilded copper. The tsuka is bound over pearl rayskin with diamond-fold paper beneath, and the saya is wrapped in stingray skin with buffalo-horn furniture. At 1.6 kg boxed it is the heaviest piece in the workshop line.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eOverall length\u003c\/td\u003e\n\u003ctd\u003e102 cm \/ 40.2 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBlade length\u003c\/td\u003e\n\u003ctd\u003e74 cm \/ 29.1 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHandle length\u003c\/td\u003e\n\u003ctd\u003e25 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBlade width\u003c\/td\u003e\n\u003ctd\u003e3.17 cm at the base, 2.5 cm at the tip\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBlade thickness\u003c\/td\u003e\n\u003ctd\u003e0.77 cm at the base, 0.51 cm at the tip\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurvature (sori)\u003c\/td\u003e\n\u003ctd\u003e2.1 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBlade steel\u003c\/td\u003e\n\u003ctd\u003e1050 sanmai lamination, clay-tempered (workshop-declared)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHamon\u003c\/td\u003e\n\u003ctd\u003eIrregular wave (workshop-declared)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBoshi\u003c\/td\u003e\n\u003ctd\u003eKo-maru\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eYokote\u003c\/td\u003e\n\u003ctd\u003eTrue yokote (cut, not simulated)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePolish\u003c\/td\u003e\n\u003ctd\u003eTwenty-four-stage hand polish (workshop-declared)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEdge\u003c\/td\u003e\n\u003ctd\u003eUnsharpened (display)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFittings\u003c\/td\u003e\n\u003ctd\u003eGilded copper (workshop-declared)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSame (rayskin)\u003c\/td\u003e\n\u003ctd\u003ePearl rayskin with diamond-fold paper\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSaya\u003c\/td\u003e\n\u003ctd\u003eStingray skin with buffalo-horn furniture\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.1 kg without saya; 1.6 kg boxed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cem\u003eHow we specify:\u003c\/em\u003e Dimensions are from the workshop sheet for this SKU.
