Henan Sifangda Superhard Materials Co., Ltd. has been working hard to apply diamond composite materials to other industries, such as shale gas mining and urban subway construction, while engaging in mining, oil and natural gas drilling. In addition to engineering applications, Sifangda in the civilian sector also developed a product in 2013 – the Diamond Escape Safety Hammer, which applies superhard materials to the tip of the hammer and is designed to escape in the car. According to the company's experiments, the glass of the high-end car is very strong, and the general escape hammer is difficult to break the window glass, and the hammer can be easily broken. When the product was produced, it was only given to the company's guests as a gift. The customer also found this kind of thing very interesting. Due to the patent application, this kind of safety hammer with diamond composite material can only be produced and sold by Sifangda in the future.
