Excalibur is a legendary sword with a sleek, double-edged blade that tapers to a sharp point, featuring a subtle wave pattern along its length reminiscent of flowing water. The blade is forged from a mysterious, gleaming metal that appears almost luminous, with a polished finish that reflects light with a faint blue hue. The hilt is wrapped in dark leather, secured with golden wire, and the crossguard is ornate, with intricate Celtic knotwork designs that symbolize its mythical origins. The pommel is a large, polished gemstone that emits a soft glow, suggesting its magical properties.
