The Reaper – Hand Forged Ceramic Coated Steel Katana Sword

The Reaper – Hand Forged Ceramic Coated Steel Katana Sword

The ceramic coating on this blade does something most wall-mounted swords never achieve: it catches light differently depending on where you stand. The Reaper (収割者-打刀) is a display katana built around that surface finish – a deep, near-black ceramic layer over rust-resistant carbon steel that shifts between matte and reflective as the viewing angle changes. Mounted horizontally against a light wall, the shinogi-zukuri (ridgeline) profile casts a clean shadow line the length of the blade.

Specifications

The Steel

The base is rust-resistant carbon steel treated with an oil quench and temper process, then finished with a ceramic coating applied over the entire blade surface. That coating is the visual story here. It is not paint and it is not bluing – it sits harder on the surface, resists fingerprints better than bare steel, and holds its dark tone without the maintenance that an uncoated blade demands from a wall piece.

The shinogi-zukuri geometry means there is an actual ridgeline running parallel to the edge, a structural feature that gives the blade its characteristic cross-section and creates that subtle two-plane effect on the flat when light hits from the side. On a display piece, that geometry does real visual work.

In Your Hands

The tsuka (handle) runs 27.0 cm / 10.6 in and is wrapped in cotton ito in the traditional diamond-pattern lozenge style – tight, even, and visually regular enough to read cleanly in photographs taken within two feet of the piece. The saya (scabbard) is solid lacquered wood in a half-K style, meaning the lower portion of the scabbard uses a wrapped or reinforced finish that adds a second visual texture below the plain lacquer body. Iron fittings throughout keep the hardware color consistent – no brass tones interrupting the dark palette of blade, wrap, and saya.

Care

The ceramic coating significantly reduces the maintenance burden, but a light wipe with a dry microfiber cloth every few weeks prevents dust from building up in the ito wrap diamonds and along the habaki (blade collar) seam. Keep the saya on when the blade is mounted and exposed to ambient air. A light application of camellia oil to the iron fittings twice a year will prevent surface rust at the tsuba (handguard) and habaki.
