As an expert in historical weaponry, I can provide you with information on a weapon that features a ball and chain. The weapon you're referring to is likely the flail. A flail is a medieval weapon that consists of two pieces: a wooden handle and a metal ball connected by a chain. The ball often has spikes or flanges, making it a dangerous and deadly weapon when swung.

The flail was used for both smashing and crushing opponents in close combat. Its design allowed for a wide swing radius and the ability to deliver powerful blows. The chain and ball mechanism also made it possible to strike around shields and other forms of protection, making it a versatile weapon in a melee situation.

Here's the translation in Chinese:

作为历史武器领域的专家，我可以为您提供有关带有球和链的武器的信息。您所指的武器很可能是连枷。连枷是一种中世纪的武器，由两部分组成：一个木柄和一个通过链条连接的金属球。球上通常有刺或凸缘，使其成为一种在挥舞时危险且致命的武器。

连枷用于近战中粉碎和压碎对手。它的设计允许有广泛的挥舞半径，并能够传递强大的打击力。链条和球的机制还使其能够绕过盾牌和其他形式的保护进行打击，使其成为混战情况下的一种多功能武器。
