Counterblade‑Katana – T10 Clay‑Tempered Reverse‑Edge Combat‑Concept Samurai Katana
Product Introduction
The Counterblade‑Katana is unique reverse‑edge combat‑concept themed samurai katana, fully differentiated from dark‑minimalist tachi, avian‑wing ethereal‑art wakizashi, wildlife‑reptile‑motif katana, gothic‑spider‑art katana, minimalist‑practical katana, zen‑bamboo wakizashi, historical‑daimyo tachi, imperial‑crest‑entry‑tachi, dragon‑theme swords, WWII military sabers and anime‑character replica swords. This concept‑driven collectible is built with premium T10 high‑carbon steel with traditional tsuchioki clay‑differential‑tempering forming distinctive sanbonsugi three‑peak hamon temper‑line. It is equipped with solid functional combat‑style plain antique‑bronze alloy mounting hardware, russet‑brown moro‑hineri cotton ito tsuka with dark‑brown faux ray‑fish samekawa inner lining, and solid hardwood finished in low‑gloss matte‑brown practical non‑ornamental lacquer, paired with thick russet‑brown heavy‑braided sageo cord. Target audiences include reverse‑blade‑concept nihonto collectors, combat‑aesthetic sword hobbyists, practical‑style static‑display lovers and distinctive concept‑theme decorative‑gift buyers.
The blade adopts premium T10 high‑carbon steel with traditional tsuchioki clay‑differential temper‑treatment, generating distinctive sanbonsugi three‑peak visible hamon temper‑line. Classic katana‑style shinogi‑zukuri blade geometry without blood‑groove hi, subtle embossed yokote dividing‑line, functional practical katana‑style kissaki tip and factory light‑sharp finish. Sanbonsugi hamon and matte‑brown practical lacquer saya scratch easily; only static combat‑concept‑theme display and photo‑shooting are allowed. Heavy chopping and violent impact must be strictly prohibited to preserve reverse‑blade‑concept themed collectible surface condition.
Complete mounting‑hardware set uses solid functional combat‑style plain antique‑bronze alloy fittings, round unadorned practical‑purpose tsuba, matching‑pattern fuchi & kashira, tiny plain antique‑bronze alloy menuki ornaments and solid‑brass habaki plus antique‑bronze alloy seppa washers. Standard katana‑length tsuka grip uses dark‑brown faux artificial ray‑fish samekawa inner lining wrapped with thick russet‑brown moro‑hineri cotton ito. Scabbard is solid hardwood finished in low‑gloss matte‑brown practical non‑decorative lacquer, fitted with antique‑bronze alloy koiguchi, kurikata and kojiri hardware; matched thick russet‑brown heavy‑braided sageo cord with antique‑bronze alloy clasp. Two natural bamboo mekugi pegs build fully‑removable full‑tang construction for blade inspection and regular anti‑rust maintenance. Combat‑concept‑theme fabric storage bag, standard katana wooden display stand and sword‑maintenance‑kit are included as full free‑gift set; custom reverse‑blade‑concept‑mark blade‑engraving upgrade available for extra charge.
