Cool Steel is a sleek, medium-length sword with a blade that shimmers with a faint blue hue, suggesting its affinity for hydro-based attacks. The handle is wrapped in dark blue leather, providing a secure grip, and the guard is elegantly designed with wave-like patterns, emphasizing its connection to water. The blade itself is slightly curved, with a sharp, polished edge that reflects light, giving it a pristine yet battle-ready appearance.
