Two-in-one emergency safety hammer / escape equipment / life-saving hammer

1. Lifeboat hammer/Safety hammer: A sharp and sturdy mallet that can be used to break the glass in case of an emergency to escape.
2. Knife: Hook-shaped embedded blade, used to cut through a seatbelt in case of an emergency to escape.

Usage Method

 1. Use of a Safety Hammer

 The lifeboat hammer is primarily used because of its conical shape. The contact area of the sharp tip is very small, so when the hammer strikes the glass, the pressure at that 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 window glass to slightly crack at that 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 strike the glass a few more times with the hammer to remove the glass shards.

 2 上车注意：

 If you are taking a long-distance bus, it is best to sit near the safety door or the roof exit. If you wish, you can take a moment to familiarize yourself with the instructions on how to open the safety door. 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!
