There are many variations of glass breakers on the market. One variation found in glass breakers is the material of which the metal tip is made from. Although all glass breakers are made of strong materials, some glass breakers make breaking glass easier than others, depending on the hardness of the metal that the tip is made of. Some sources have found that tungsten carbide tips make breaking glass less difficult. However, laminated glass cannot be broken by any glass breakers on the market. Glass breakers are only effective on tempered windows.

Spring Loaded Glass Breaker
Glass breakers come in two styles, hammer and spring loaded. Spring loaded glass breakers take away the need to swing a tool to break a window. The metal tip is simply held up against the window and either a pin is pulled back and released to activate a spring, or the spring is pulled back by the user directly. This type of glass breaker is designed to be used underwater or to simply reduce the amount of strength needed to shatter a window. When a car is submerged underwater, a hammer style glass breaker becomes significantly more difficult to use. While this type of glass breaker is convenient and easier to use, most spring loaded glass breakers are limited to the force of the spring. The could limit the user's ability to break glass.

Larry Goodman's Safety Glass Breaker
Larry Goodman is an inventor of a safety glass breaker that utilizes a 22 blank cartridge to ensure enough force is applied to break a window on the first try. Other spring loaded glass breakers deteriorate over time due to the spring wearing out, this device relies on expanding gasses. The user pulls back a firing pin to compress a spring, once the pin is released the spring pushes the pin into a 22 blank cartridge. This device is also designed with the user’s safety in mind. The device is firing a blank round, so there is a lot of power in this handheld device that could injure the user. The striker point is designed to only come out of the device about 0.6 inches.
