3-In-1 Car Escape Tool: The car safety hammer with a sharp tip and a flat end is made of alloy. The sharp stainless steel seatbelt cutter can cut off seatbelt to release drivers and passengers in the shortest time. Its handle is manufactured by integral molding of Aluminium Alloy, making it durable and fireproof. Fireproof and Underwater: The reason why we insist on alloy production is that when the vehicle catches fire, cheap plastic products will be melted, but pure metal production will not affect the use at all, which is a safer option for driving. The sturdy heavy hammer allows you to use 1 second to escape underwater. Ergonomic Safety Hammer: The safety hammer has a super long nonslip handle, which can provide a better grip than other normal models and keep your hand away from the broken glass.
