[Compact and Powerful Safety Tool]: This two-in-one safety hammer is a compact and reliable emergency tool designed for use in vehicles. It features a durable window breaker and a seatbelt cutter, providing a quick exit solution in emergency situations. Measuring just 3 inches, it can be conveniently stored or mounted in a vehicle’s center console using the included Velcro strap. [Dual-Head Efficient Glass Breaker]: This safety hammer has a dual-head design with a solid tungsten steel impact tip rated at hardness 55. The dual-point design delivers up to 6kg of impact force. Its precise mechanical structure and spring-loaded ejection mechanism enable instant glass shattering in 0.1 seconds, even underwater. The replaceable impact tip allows for multiple uses. [Hidden Blade Design]: The concealed blade enhances safety during storage and handling. When activated, the blade extends smoothly and locks securely, allowing the user to grip the safety hammer body as a handle. Position the U-shaped blade edge against a jammed seatbelt and cut diagonally for fast and effective escape. The blade is designed for repeated use. [Widely Applicable]: This seatbelt cutter and window breaker offers added security for drivers and passengers. In emergencies such as vehicle submersion, collision, rollover, or fire, electric windows may fail. Unlike traditional hammers that require significant force, this tool’s mechanical ejection system enables rapid escape without relying on manual strength. [Please Note]: The window breaker contains sharp spring-loaded impact tips. Do not press the hammer head with your hand or direct it toward any person to prevent injury. Use only as intended.
