Due to the small contact area of the tip, when using the hammer to smash glass, the pressure on the glass at that contact point (not pressure, but pressure per unit area) is quite high. This is similar to the principle of a pushpin, where the membrane is easily punctured and the car glass is subjected to a large external force at that point, causing slight cracking. For tempered glass, a small crack means that the stress distribution inside the entire glass is disrupted, resulting in countless spider web like cracks in an instant. At this time, as long as the hammer is lightly used to smash it a few more times, the glass fragments can be removed. The middle part of tempered glass is the strongest, while the corners and edges are the weakest. The method is to use a safety hammer to strike the edges and corners of the glass, especially the middle part of the edge above the glass. Once there is a crack in the glass, you can strike it a few more times. It is said that about 2 kilograms of pressure can smash the corners of tempered glass If there were no safety hammers, women's high heels would also be a great thing. Swing the heel up and use your strength to smash it, the thinner the heel, the better 2. Attention when getting on the car: If taking a long-distance bus, choose to sit closer to the safety door or roof. If you are willing, you can carefully read the instructions on how to open the safety door, because once an accident occurs, you cannot calmly read the instructions. Product Features When a car has an accident (such as a rollover or falling into a river) and needs to escape, you can use the cutting knife at the end of the life hammer to cut the safety belt, then use the pointed life hammer to break the car window glass, and then jump out of the car to escape. It is the last protective barrier for passengers' lives Product feature introduction: This product has excellent exterior design and is quite remarkable: compared to other similar products, it is more user-friendly and more in line with practical needs. For example, its tail end is a protruding hook, unlike some products where this part does not protrude and is flush with the handle, which increases the difficulty of emergency use. Imagine, how many people would calmly aim their seat belts at the gap of the cutting knife in an emergency? And our product is much more convenient to use. In emergency situations, as long as people wave it towards the seat belt, its extended hook will naturally hook onto the seat belt and slide it into the notch cutter. In addition, its base design makes the product firmly fixed, so that it will not fall off even if the car bumps. Moreover, it can be easily removed once needed
