1. Use of a Safety Hammer

The lifeboat hammer is primarily used for its conical tip, which has a very small contact area. Therefore, when hitting the glass with the hammer, the pressure at this contact point (not the force, but the force per unit area) is quite high. This is somewhat similar to the principle of a paperclip, which easily pierces the film and causes the car glass to slightly crack at this point due to a large external force. For tempered glass, even a small crack means the internal stress distribution of the entire piece of glass is compromised, leading to the instantaneous formation of countless spider web-like cracks. At this point, it is only necessary to lightly hit the glass a few more times with the hammer to remove the glass shards.

The middle section of tempered glass is the strongest, while the corners and edges are the weakest. The best way to break the glass is to hit the edges and corners with a safety hammer, especially the middle part of the upper edge. Once the glass has a crack, you can break it by hitting a few more times. It is said that about 2 kilograms of pressure can break the corners of tempered glass.

If you don't have a safety hammer, a woman's high heels can be quite useful. Swing the heel with all your might, and the thinner the better!

2 上车注意：

If you are taking a long-distance bus, it is best to sit near the emergency exit or the roof exit. If you wish, you can take a moment to familiarize yourself with the instructions on how to open the emergency exit, as in the event of an accident, you won't have the time to calmly read the instructions.

Product Features

When a car accident occurs, such as a car rollover or falling into a river, if you need to escape from the car, you can use the knife on the end of the lifebuoy to cut the seatbelt, and then use the sharp-pointed lifebuoy to break the car window glass. Then jump out of the car to escape. It is the last line of defense for the passengers' lives!

Product Features Introduction:

This product is exceptionally designed in terms of appearance, with many commendable features: compared to similar products, it is more humanized and more in line with actual needs. For example: its tail end is a protruding hook, unlike some products where this part is not protruding, level with the handle, which increases the difficulty in use in an emergency. Imagine how many people will calmly align the seatbelt with the cutter's gap in an emergency? With our product, it is much easier to use in an emergency. People can simply swing it over the seatbelt, and the protruding hook will naturally catch the seatbelt and guide it into the cutter's gap. Additionally, the base design ensures that the product is firmly fixed on top, remaining stable even during car vibrations, and it can be easily removed when needed.
