A window breaker is a small tool designed to break the windows of a car or other vehicle in an emergency situation.

A window breaker can be useful in a variety of emergency situations, such as if you are trapped inside a car after an accident, or if you need to quickly exit a vehicle that is on fire or submerged in water.

A window breaker either consists of a safety hammer that is swung at the glass or works by using a spring-loaded mechanism to strike the window with a pointed tip, which breaks the glass. Some window breakers also have a seatbelt cutter built in to help you escape if your seatbelt is stuck.

Yes, window breakers are legal to own and carry in the UK.

The cost of a window breaker can vary depending on the brand and features, but they typically range from 拢5 to 拢20.

In most cases, a window breaker can be reused multiple times, but it may need to be replaced if the spring or tip becomes damaged or worn over time.
