A sleek, curved single-edged sword with a long, slender blade, traditionally used by samurai. The blade features a subtle hamon (temper line) and a polished, mirror-like finish. The handle is wrapped in dark blue or black silk or leather, secured with a decorative menuki (ornament) under the wrap, and capped with a small, circular guard (tsuba) that may feature intricate designs. The scabbard (saya) is made of lacquered wood, matching the handle's color scheme, with a smooth texture and possibly minor wear or scratches indicating use.
