A sword is a hand-held weapon made for cutting. It is often made of metal. It has a long blade, and a handle called a hilt. Often there is some form of hand protection, such as a cross-guard or a basket. It can be used either for cutting, slashing or stabbing, depending on the type of sword.

Swords hitting each other Clash is a common word for that. Just before that, there is a high-pitched noise apparently made by the sword moving through the air - that might be called whining or whistling or singing.
