Scarlet Cherry Moon – Hand Forged T10 Tool Steel Katana Sword

Scarlet Cherry Moon – Hand Forged T10 Tool Steel Katana Sword

The Scarlet Cherry Moon is a T10 tool steel katana that immediately sets itself apart through its premium copper fittings — a warm, reddish-gold metalwork suite that evokes the color of ripening cherries against a harvest moon, and elevates this sword well above iron-fitted peers at the same blade specification. Copper tsuba and copper fuchi-kashira (collar and pommel fittings) are significantly more costly to work than iron or zinc alloy, and their distinctive warm patina deepens naturally over the years, making each Scarlet Cherry Moon increasingly unique with age. At $350, this is the highest-priced katana in the core T10 iron/copper tier — and the copper fittings are the reason why.

Craftsmanship & Materials

Copper has been used in sword fittings across Asia for centuries precisely because it occupies a unique aesthetic middle ground: warmer and richer than iron, more restrained and serious than gold, and possessed of a living surface that shifts from bright salmon-pink when freshly polished to deep, complex terracotta as natural oxidation develops. On the Scarlet Cherry Moon, the copper tsuba is hand-finished and features the same care in its construction that the blade receives — weight-balanced, properly seated, and fitted without play against the habaki (blade collar). The copper fuchi-kashira complete the visual unity, tying the handle assembly to the guard in the same warm metallic language.

Beneath this striking furniture, the T10 blade undergoes the same clay-tempering process that defines the best functional katanas from Longquan: clay slurry applied to the spine, a carefully controlled quench to develop differential hardness, and hand-grinding to reveal the hamon along the ha. T10’s tungsten-enhanced hardness makes the edge exceptionally resistant to deformation under cutting loads, while the clay-insulated spine retains the toughness needed to absorb shock without cracking. The shinogi-zukuri (鎬造) geometry — with its clear ridgeline dividing the blade into distinct facets — is both structurally optimal and visually classical.

The tsuka brings the warmth theme full circle: cotton ito in a traditional wrap over genuine same rayskin, with the rayskin’s natural cream-white texture visible in the diamond windows between ito passes. The high-gloss lacquered hardwood saya provides a dark mirror that makes the copper fittings appear to glow when the sword is sheathed — an effect that photographs beautifully and impresses even more in person.

Perfect For

• Serious collectors who prioritize fittings quality and understand that copper metalwork represents a meaningful step above iron at a similar blade specification
• Display and dojo owners seeking a katana that commands attention on a sword stand while remaining fully functional for cutting practice
• Long-term collectors who appreciate that copper fittings develop a unique, personalized patina over years of ownership — making the sword increasingly one-of-a-kind

Care & Maintenance

The T10 blade requires regular oiling with choji or mineral oil to prevent rust — wipe clean after every handling and apply a fresh coat monthly, taking particular care around the habaki where moisture collects. The copper fittings will naturally darken and develop a patina over time; if you prefer to preserve the bright copper finish, apply a thin coat of Renaissance Wax to the metal fittings annually and buff gently with a soft cloth. Never use acidic or abrasive cleaners on either the blade or the copper, as both surfaces are sensitive to chemical damage.
