Spring steel is also commonly used in the manufacture of metal swords used for stage combat due to its resistance to snapping or shattering.[dubious– discuss] Spring steel is one of the most popular materials used in the fabrication of lockpicks due to its pliability and resilience. Tubular spring steel is used in some of the smaller aircraft's landing gear due to its ability to absorb the shock from landing & also acts like damping.
