Specifications

Craftsmanship & Materials

Night Calm is forged from 1045 carbon steel subjected to a special processing treatment that refines the grain structure beyond what standard mill-run 1045 typically offers. With a mid-range carbon content, this steel strikes a balance between toughness and workability — it absorbs impact without the brittleness that higher-carbon alloys can exhibit, making it a sensible choice for those who want a functional katana that can withstand regular handling. The oil quench and temper heat treatment process locks in that balance, producing a blade with enough edge retention for light cutting practice while maintaining the spine flexibility the Shinogi-Zukuri geometry was historically designed to exploit.

The Shinogi-Zukuri ridgeline forging style is the classic cross-section of the samurai katana: a raised central ridge divides the blade into a shinogi-ji (ridge flat) and a ha (cutting edge bevel), creating both structural rigidity and the elegant taper that defines the sword’s visual character. On Night Calm, this geometry is expressed cleanly and without ornament, letting the quiet geometry speak for itself — much like the calm of a still night the name evokes. The saya (sheath) is shaped from Aohada green bark wood, whose naturally textured surface provides a subtle organic contrast to the steel.

The cotton ito wrap on the tsuka (handle) is wound in the traditional diamond-pattern over the grip, offering a secure and comfortable hold across a 27 cm handle length. While zinc alloy fittings place Night Calm honestly within its entry-to-mid price tier, they are finished with care and contribute to the sword’s unified, understated aesthetic — a blade that earns its name through quiet confidence rather than flashy ornamentation.

Perfect For

• First-time katana buyers seeking an authentic Shinogi-Zukuri profile at an accessible price point
• Display and decorative use in home dojo, study, or martial arts space where visual authenticity matters
• Beginners exploring sword handling, kata practice, and basic tameshigiri under supervised instruction

Care & Maintenance

1045 carbon steel will develop surface rust if left unprotected — wipe the blade clean after every handling session and apply a light coat of choji oil or mineral oil along the entire length before storage. Keep the sword in its Aohada saya in a low-humidity environment, and never store it sheathed for extended periods without periodic inspection. Avoid contact with salt, moisture, and acidic skin oils, which can accelerate oxidation on this steel grade.
