What is the purpose of a swivel in automotive tools?

The purpose of a swivel in automotive tools is to allow flexibility in reach. Swivels are designed to enable tools to pivot or rotate, which can be particularly beneficial when working in tight or awkward spaces where direct access is limited. This flexibility allows the user to position the tool more effectively, making it easier to apply force or adjust angles without having to reposition the entire tool or their body. Such adaptability is essential for reaching difficult fasteners or components within the engine bay or undercarriage of vehicles, enhancing efficiency and effectiveness during repair or maintenance tasks.
