Forged in Longquan
永夜之拥 – Eternal Night’s Embrace – is a piece built around darkness rendered as craft. The blade is forged in shinogi-zukuri (鎬造) form, the classical ridgeline profile of traditional Japanese swordsmithing, and finished through a special surface process that gives it a deep, light-absorbing character unlike a raw polished blade. The 1045 carbon steel receives this treatment after forging and tempering, the result being a blade that does not throw light back aggressively but instead holds it, pulling the eye along the length of the curve. Against that restrained blade, the saya speaks loudly. The solid wood body is finished in high-gloss piano lacquer and then cut with hollow carved floral relief – three-dimensional openwork patterns that cast their own micro-shadows across the lacquer ground. The contrast between the matte-edged carvings and the mirror lacquer between them is the kind of surface detail that photographs exceptionally well and reads equally well in person.
Weight, Balance, Draw
The 27 cm cotton-wrapped handle gives a confident two-hand grip, the diamond ito pattern pressing into the palm with enough texture to feel deliberate. The draw from the lacquered saya is smooth and controlled – piano lacquer over solid wood produces a stable, tight fit that seats and releases cleanly without the roughness of painted or wrapped sheaths. When the blade clears the koiguchi (the mouth of the sheath), the deep-finished blade reads almost black against the gloss saya, then shifts as the angle changes. Displayed on a horizontal wall mount, the carved relief of the saya faces outward, and the overall composition – dark blade, ornate sheath, diamond-patterned handle – is dense with visual detail at any viewing distance.
Keeping It Sharp
Keep the blade surface clean with a soft cloth and a light application of camellia or mineral oil applied with a clean patch every few months. The piano lacquer saya responds well to gentle dusting with a soft brush – avoid abrasive cloths on the carved relief sections. Store away from direct sunlight to preserve both the blade’s surface finish and the depth of the lacquer.
