The Fūma Shuriken is a large, four-bladed throwing weapon with a distinctive star shape, featuring sharp, angular blades that taper to deadly points. Each blade is slightly curved for aerodynamic efficiency, with a central circular grip wrapped in dark fabric for secure handling. The metal surfaces are polished to a high gloss, reflecting light with a metallic sheen, while the edges are finely honed to emphasize their lethality. The shuriken's design includes subtle engravings along the blades, adding a touch of ornate detail to its otherwise functional appearance.
