  2. Aim at the corner. No matter whether you are planning to save someone from a closed vehicle or rescue yourself, the main idea to deliver here is to make the window break by hitting its corner. The bottom corner and upper corner may be too dangerous, so probably choose the side of the window.
  3. Use a reflective strip. Although most glass breakers have this option, you can customize one for yourself. It is a highly important part of the tool as it will help you to seek the window breaker underwater or in the darkness.
  4. Safety is the foremost. Never forget that breaking glass usually causes serious injuries. Thus, when you break the side window upon yourself, cover your head and preferably dodge from the glass break.
  5. Practice makes perfect. Except for exploring the material of the tip before starting the usage, it is better to practice the hitting technique. If you use a hammer, you should know which force is needed and how many hits you can make. If you use a spring-loaded escape tool, try to see how the mechanism works at all.
