SafeHammer New Customer Reviews Once the pressure reaches a specific trigger point—typically around 20kg of force—the spring releases instantaneously, propelling the tungsten steel spike forward at a high velocity. This mechanism is what allows SafeHammer to be used effectively even when the user is underwater, as the force is generated internally rather than through external movement that would be hampered by water density.
SafeHammer New Customer Reviews The heart of the SafeHammer glass breaker is its tungsten steel head, which boasts a hardness rating of 55+ on the Rockwell scale, allowing it to easily pierce through the tempered glass found in most car side and rear windows. This high-density tip is housed within a casing made of high-quality Polycarbonate (PC) or reinforced aluminum alloy, depending on the specific model chosen, providing a lightweight yet rugged exterior that can withstand the rigors of an emergency. The impact force generated by the internal spring mechanism is approximately 20 kilograms of concentrated pressure, which is more than enough to instantly crumble tempered glass into small, relatively safe fragments. Measuring between 3.5 to 4.4 inches in length and weighing between 50g and 150g, SafeHammer is remarkably portable, often coming with a dedicated plastic holder and 3M adhesive tape or Velcro for secure mounting on the dashboard or center console.
