Shattered Star – Hand Forged 1045 Carbon Steel Katana Sword
Shattered Star (碎星) is a katana with a distinctive edge: the 1045 carbon steel blade undergoes a special surface treatment process that gives it visual character beyond a standard polish. The name suggests a star broken into fragments — fitting for a blade whose surface treatment creates unique light-catching patterns along the steel.
Forged in Longquan with the shinogi-zukuri geometry, the 72cm blade is tempered using a furnace-and-anneal process. The saya is particularly noteworthy — solid wood with a piano lacquer finish featuring an openwork (空心花) carved pattern that adds visual depth. At $159.99, the Shattered Star commands a modest premium over the standard models for its special treatment and decorative saya.
This blade suits collectors who want something with visual distinction — the kind of sword that draws the eye on a display wall and rewards close inspection.
