As the newest member of the Swiss+Tech family of quality made 'micro-tools', BodyGuard incorporates these five specific devices: automatic window punch, seat belt cutter, sonic alarm, flashing red distress light, and bright-white LED flashlight. The new BodyGuard 5-in-1 Emergency Tool is designed to help drivers escape from their vehicles when the windows or doors fail to operate due to vehicle damage, fire or submersion. The automatic window punch is spring-loaded to automatically deploy when pressed firmly against a vehicle's side or rear window. The seat belt cutter quickly frees boththe driver and passengers from their seats if their seatbelts do not unlatch after a vehicular accident. When not in use, the blade is housed securely within the casing to prevent accidental cutting. Both the window punch pin and seat belt cutter are make of high-carbon steel for maximum durability. BodyGuard is also impact-resilient and water-resistant, with a tough ABS construction and a limited lifetime warranty. If comes complete with a replaceable battery and instructions for care and use. At less than 3"x1-3/4"x5/8" in size, and weighing only one ounce, BodyGuard attaches securely to a key ring and releases with a quick tug for fast emergency use.
