How to break glass using the glass breaker knife

We hope you never find yourself in a situation where you need to break a car window, but it's always good to be prepared. If you're ever in an accident or your car is submerged in water, you may need to break a window to escape.

But before you start smashing away, there are a few things you should know. First, choose a side window. Your windshield is coated with a material that prevents it from shattering, so even though it may break, it won't open.

The side windows don't have this coating. Next, make sure to break the corner of the window. The corners of the window are the weakest, so whether you're saving yourself or someone else from outside, strike the corners and they'll break quickly.

Just a note: have a safety precaution for your hand while breaking if possible, as safety glasses are sharp. But we have a fix for this mentioned ahead.

Finally, if you use it as a rescue knife to rescue someone from a sinking car, use a piece of cloth or another object to cover the broken glass before you enter the vehicle. This will prevent you from being cut by the glass as you climb inside. With these tips in mind, you'll be ready to break a window if the need ever arises.

We hope you never get in such a situation where you need rescue knife tips. But, it is always better to know.
