Analysis of the correct use of safety hammer

How to use: The safety hammer is mainly used with its conical tip, because the contact area of ​​the tip is very small, so when the glass is hammered with a hammer, the contact point pressure on the glass (not the pressure, but the pressure per unit area) This is quite large. This principle is somewhat similar to the thumbtack. The film is easily pierced, and the car glass is exposed to a large external force at this point and causes slight cracking. For tempered glass, a little cracking occurs. This means that the stress distribution inside the entire glass has been destroyed, resulting in countless spider web cracks. At this moment, you can remove the glass fragments with just a few taps with a hammer.

In addition, the middle part of the tempered glass is the strongest, with the four corners and the edges being the weakest. The best way is to hit the edges and corners of the glass with a safety hammer, especially in the middle of the top edge of the glass. Once the glass cracks, it is easy to smash the entire glass.
