Last updated: June 2023
Just like our previous buyers guides were we have written about emergency blankets and first aid kits, another important product is that of an emergency hammer, window breaker and safety multi tool.
Here we review the best car window breakers, emergency hammers and emergency multi-tools. We have a look at five different tools and car window breakers to see what is the best value for money to have in your car at all times, and what can do the best job for you when you need it. The car window breakers/seat belt cutters are definitely in the category of tools that you don’t want to be needing to use and would be happy if they just collect dust in your car.
Alas, car accidents are unpredictable and can occur at any time. In some situations, the vehicle’s doors or seat belts may become jammed, trapping the occupants inside. This is where a car escape tool becomes invaluable. It can cut through jammed seat belts and shatter windows, providing a quick escape route.
In the event of a car submerging in water or catching fire, every second counts. The power windows may fail due to electrical short-circuiting, and the pressure difference can make it nearly impossible to open the doors. A car escape hammer can be the difference between life and death in these scenarios.
Car escape tools are typically compact, handheld devices designed to perform two main functions: cutting seat belts and breaking windows.
Seat belt cutter – is a sharp, guarded blade that can slice through a seat belt’s material quickly and safely. This feature is crucial if the seat belt mechanism is jammed and cannot be released normally.
Window breaker – on the other hand, is a pointed, hardened steel or tungsten tip designed to shatter tempered glass. A forceful swing or push against the corner of a side window is usually enough to break it. Remember, the windshield and rear window are often laminated and are much harder to break.

Choosing the Right Tool
When purchasing a car escape tool, consider the following factors:
Quality: Look for tools made from high-quality, durable materials. The window breaker should be made from hardened steel or tungsten, and the cutter should be sharp and well-guarded.
Ease of Use: The tool should be easy to handle and operate, even under stress. Look for an ergonomic design that fits comfortably in your hand.
Accessibility: Choose a tool that comes with a mount or holder. It should be stored within arm’s reach, like in the center console or attached to the driver’s side door, so it’s easily accessible in an emergency.
The emergency hammers come in many different forms, some are simple hammers, made for breaking glass and getting out of a car you might be trapped in. A couple of the hammers have advanced tools on them which can help you cut your eat belt and one even has an emergency light beacon and torch on it as well.
Car window breakers and emergency hammers don’t cost much to purchase and can come in handy for yourself or whether you find someone else stuck in a car or locked behind their seatbelt.
We have ranked the AA 3 in 1 Emergency Beacon as the best car window breaker and emergency hammer. It’s fantastic multi-tool use means that you get more than just a window hammer. Even though it’s called a 3-in-1 emergency beacon, it actually has 4 tools on it.
It has a beacon, a seat belt cutter, a torch and importantly a window breaker. With some batteries placed inside you know you have a tool that you can keep in your car and use in a number of circumstances.
We have put the Lifehammer Classic Glow Emergency Hammer in at second because it’s a very simple tool and as well as being able to cut through a seatbelt, it’s also glow in the dark.
The Ipow and the Resqme car glass breakers are both very simple car window breaker and emergency tools. The resqme comes with a seat belt cutter attached to the top and the Ipow has it’s seat belt cutter near the bottom of the handle. They are both simple tools but do the job intended very well!

AA 3-in-1 Emergency Beacon
This is a review of the AA 3-in-1 Emergency Beacon
The AA 3 in 1 Emergency beacon arrives in a surprisingly small package, weighing only 200g this little device packs quite the punch. Designed to be of assistance in a multitude of emergency situations when out on the road.
The lower section of the device serves as a 360 flashing beacon light which provides very bright red light using LED’s that can be seen from 500 metres away.
To the end of the device is an additional light for general use, however I would recommend buying a extra torch for general use and using this torch only in emergencies to preserve the batteries (which are included). To the other side of the device is a strong magnet which means you can turn the torch or beacon on, attach the magnet end to your car allowing you to do something else such as checking under the bonnet, calling the emergency services or your break down recovery.
Added to the above elements car evacuation features such as the seat cutter and the robust hammer to shatter car window glass. The seat cutter is simple to use you will just need to remember to hold at a particular angle to catch the blade on the seat belt. The hammer itself is easy to use and just requires you to strike the window with the steel point to the head of the device.
This is an extremely handy tool the only two elements for consideration is that it doesn’t come with a mount to use in the car and that it is worth familiarising yourself with where things are on the tool, how they work and that the batteries are charged.
Verdict
The AA 3 in 1 emergency beacon is a value for money multitude of emergency tools in a tiny package that could be a life saver in an emergency situation.
