The Spiral Cloud Passage is a unique, ornate katana with a slightly curved, single-edged blade that features a distinctive spiral pattern along its length, resembling swirling clouds. The blade is forged from high-quality steel with a polished, reflective finish, while the handle is wrapped in dark blue silk with golden thread accents, secured by a circular guard depicting a cloud motif. The overall design is elegant yet functional, embodying the artistry of feudal Japanese sword-making.
