Clyfanesy 2 x Safe Car Emergency Hammer with seatbelt cutter
Product description
This compact emergency tool combines a seatbelt cutter and a window breaker, providing a quick way to exit a vehicle in extreme situations. As a practical car emergency hammer, it is small enough to keep near the driver yet engineered to break glass rapidly, which can make the difference when seconds count.
Key Points
The design merges a razor-sharp stainless steel seatbelt cutter with a hardened striking tip for shattering car windows. Its U-shaped recessed blade reduces the risk of cutting the user while making swift work of tangled or jammed belts. 🛠️
Light and pocket-sized, each hammer measures approximately 112 × 18 × 21.5 mm and weighs about the same as a set of keys, so it can be stored on a keyring or attached to an adhesive disc in the cabin for visible, easy access. The product is sold as a pack of two, allowing one to be kept with the vehicle and another placed in a bag or glovebox. 🔑
According to the manufacturer, the striking tip is designed to function even under water, with improved resistance to water pressure compared with ordinary safety hammers. Consider that performance under extreme conditions may vary with window type and depth.
Technical Specifications


- Name: Clyfanesy 2 x Safe Car Emergency Hammer
- Size: 112 × 18 × 21.5 mm
- Pack contents: 2 hammers
- Blade material: stainless steel seatbelt cutter
- Hardness rating: up to 55 (manufacturer statement)
Usage Recommendations
Keep one hammer within immediate reach of the driver and the second in a frequently used bag or next to the child seat. For rapid escape, pull the seatbelt across the U-shaped cutter and pull firmly to sever the webbing. To break a side window, strike one of the corners rather than the centre and then push clear glass away from the opening to create an exit path.
If you plan to attach the tool to a visible location inside the car, use the included adhesive disc to secure it where it will not be blocked by covers or personal items. Periodically check that the cutter blade is free of debris and that the adhesive pad remains sticky, especially after cleaning or temperature changes.
Benefits
Small dimensions and light weight mean the tool is highly portable and unobtrusive in daily use. The recessed blade lowers the chance of accidental cuts during handling, which can be reassuring for those less confident with hand tools. The pair format offers redundancy so you have a spare device available after an incident or if one is misplaced.
A realistic limitation is that the hammer’s effectiveness depends on the window composition and the nature of the impact. Also, while the tool is described as capable of breaking windows underwater, deep water or unusual glass types may reduce its effectiveness, according to the manufacturer.
