2500-YearBronze Sword

King Fuchai of Wu's Sword is a 2,500-year-old bronze weapon, now housed in Suzhou Museum. It measures 58.3 cm in length, with a design that highlights the peak of bronze-forging technology of the Wu State. King Fuchai of Wu's Sword narrows near the tip to enhance piercing power, and its crossguard is decorated with beast-face patterns inlaid with turquoise. Its pommel features seven layers of delicate concentric circles, which were cast separately with different bronze alloys and then joined to the hilt—a craft that remains difficult to replicate even today. Through composite casting, King Fuchai of Wu's Sword balances toughness (the spine with low tin content) and sharpness (the edge with high tin content). After 2,500 years, it still retains extraordinary sharpness and can easily cut through 12 layers of rice paper with its own weight. 吴王夫差剑是一柄有 2500 年历史的青铜兵器，现藏于苏州博物馆。吴王夫差剑全长 58.3 厘米，其设计尽显吴国青铜铸造技术的巅峰水准。吴王夫差剑近锋处收狭，以此增强穿刺力；剑格饰有兽面纹，且镶嵌绿松石作为点缀；剑首铸有七层纤细的同心圆，采用不同青铜合金分铸后再衔接而成，这项工艺即便在现代也难以复刻。通过复合铸造技术，吴王夫差剑实现了韧性（剑脊低锡含量）与锋利度（剑刃高锡含量）的平衡。历经 2500 年，吴王夫差剑仍保持着极强的锋芒，仅靠自身重量就能轻松划开 12 层宣纸。
