City’s Ruin – Hand Forged 1045 Carbon Steel Katana Sword

City’s Ruin – Hand Forged 1045 Carbon Steel Katana Sword

焚城劫 – City’s Ruin. The name carries weight before the blade even leaves the sheath. This is a katana built to command a wall, a display stand, a room. The piano-lacquer hardwood saya (sheath) catches light the way lacquered furniture does – deep, glassy, with a finish you want to run a finger across. Against that polished surface, the alloy fittings read crisp and intentional.

Specifications

The Steel

The blade is forged from 1045 carbon steel using a special process that gives the surface a distinctive visual character. The shinogi-zukuri (ridge-line blade geometry, the classic katana profile with a defined central ridge) runs the full 72 cm of blade length, casting a clean shadow line that photographs exceptionally well from above or at a low angle. The finish has a matte-to-satin quality that sits in natural contrast against the high-gloss saya below it on a horizontal mount.

At 3.2 cm across the blade, the geometry is substantial. Mounted horizontally, the sword reads as a full-scale display piece – not a miniature, not a prop. It occupies space the way a serious object should.

In Your Hands

The 27 cm handle is wrapped in cotton ito (handle cord) in a diamond-pattern weave that photographs cleanly and holds its geometry over time. Pick it up and the grip texture is immediately present under your palm – firm, consistent, with the characteristic raised diamonds of a traditional tsuka (handle) wrap. The draw from the piano-lacquer saya is smooth, with a soft resistance that breaks cleanly. Mounted on a wall stand or carried to a display case, City’s Ruin presents every angle with the same composed authority.

Care

Wipe the blade occasionally with a lightly oiled cloth to prevent surface oxidation, especially in humid environments. The piano-lacquer saya should be kept away from prolonged direct sunlight, which can yellow or dull the finish over time. Cotton ito wrap benefits from a gentle brush-down if dust accumulates in the diamond channels.
