The Black Knight Glaive is a formidable polearm with a long, curved blade attached to a sturdy, dark metal shaft. The blade features a menacing, serrated edge and is adorned with intricate, fiery engravings that glow faintly, suggesting its cursed or enchanted nature. The shaft is wrapped in worn, black leather for grip, and the overall design is both elegant and deadly, with a balance that suggests it's designed for sweeping, powerful strikes.
