This is an emergency escape tool for cars. It can break side windows with its sharp head and cut seatbelts with the built-in cutter. Please note that windshields are difficult to break. It's reassuring to keep it near the driver's seat at all times. Specifications: ・Model: BS-975 ・Material: Carbon tool steel + ABS resin ・Manufacturer: Toyomitsu Co., Ltd. (TMC CORP.) I have one in my car, but I no longer need another since I sold my previous car. It provides peace of mind as an emergency tool in the car. I will ship it promptly after purchase.
