Koi Set – Hand Forged 1065 Carbon Steel Katana Sword
The Koi Set — 锦鲤套装 — takes the beloved Koi katana and elevates it into a complete, matched daisho-style pairing that delivers an immediately giftable, display-ready ensemble at the $290 premium tier. This is the same hand-forged 1065 high carbon steel blade and signature Aohada green bark wood saya, now presented as a coordinated set that multiplies the visual impact of a single sword into a statement collection piece. For those who believe that context transforms an object into an experience, the Koi Set is the obvious choice.

Craftsmanship & Materials
The Koi Set shares its DNA with the individual Koi katana — the same shinogi-zukuri ridgeline geometry, the same oil-quenched and tempered 1065 high carbon steel, the same 72 cm blade ground to a functional cutting edge in the workshops of Longquan. But a set is more than the sum of its swords. The matched Aohada green bark wood sayas create a visual harmony that speaks to the Japanese tradition of the daisho — the paired long and short swords worn together as a unified statement of identity and craft. Presented side by side, the coordinated fittings and wrap colours create a sense of intentional design that elevates the entire display.
The cotton ito wraps on both handles are applied using the traditional diamond-pattern binding technique, providing a secure, non-slip grip while maintaining visual consistency across the set. The alloy fittings — tsuba, fuchi, and kashira — are matched across both pieces, ensuring that the set reads as a designed whole rather than two swords that happen to share a colour palette. This level of coordinated craftsmanship is exactly what distinguishes a curated set purchase from buying two swords separately.
The 1065 steel performs identically across the set — oil quenching provides a hardness level well-suited to functional cutting, while the tempering step ensures that neither blade is brittle. Both swords are test-fitted and inspected before shipping to ensure that tsuka and tsuba are seated correctly and that each blade draws cleanly from its Aohada saya.
Perfect For
- Display collectors who want a visually cohesive, wall-mounted or stand-displayed set that commands attention in a home office, dojo, or dedicated sword room
- Martial artists practising paired sword forms who need matched blades in consistent weight and length ratios
- Premium gift givers looking for a meaningful, hand-forged birthday, graduation, or milestone gift that arrives as a complete, presentation-ready package
Care & Maintenance
Both 1065 high carbon steel blades require the same consistent care: oil lightly after every handling session using camellia or food-grade mineral oil, and store in a stable, low-humidity environment to prevent oxidation. When displaying the set on a stand, ensure adequate air circulation around both sayas and rotate the blades out of their sheaths every few months to check for any moisture accumulation inside the wooden saya. A soft, lint-free cloth for wiping and a dedicated oiling kit are the only tools you will ever need to keep the Koi Set in pristine condition.
Frequently Asked Questions
What is 1065 high carbon steel and why is it used in the Koi Set katana?
1065 high carbon steel offers approximately 0.65% carbon content, delivering a dependable balance of sharpness and durability. It resists chipping under impact while maintaining a keen cutting edge — qualities that matter for regular use. In the Koi Set katana, 1065 steel ensures the blade performs reliably for both display and cutting practice, making it accessible to beginners and enthusiasts alike.
What is included in the Koi Set and what makes it different from the single Koi katana?
The Koi Set (LQS-0102) expands on the standard Koi katana (LQS-0101) by bundling the sword with additional matching accessories or companion pieces under one purchase. Both share identical blade specifications — 1065 steel, 72 cm blade, Shinogi-Zukuri geometry, and the signature Green Bark Wood (Aohada) sheath — making the set the better value if you want a complete, coordinated Koi collection.
Is the Koi Set katana functional and suitable for cutting?
Yes. The Koi Set katana is fully functional, featuring a 1065 high carbon steel blade with oil quench and temper heat treatment. At 72 cm in blade length and 950 g net weight, it is properly balanced for tameshigiri and iaido practice. The cotton ito handle wrap and Shinogi-Zukuri blade geometry align with functional sword standards, making it a capable cutter as well as a visually striking display piece.
Is the Koi Set worth $290 compared to buying the Koi katana alone at $160?
The Koi Set at $290 offers meaningful savings over purchasing the Koi katana and its companion pieces separately. Both products share the same handmade 1065 steel blade, Aohada sheath, and cotton ito wrap. If you want the complete Koi aesthetic — or are buying as a gift requiring a full presentation — the set delivers better overall value. Buyers wanting only a single functional katana may prefer the $160 Koi.
