Glass-breaking pliers are a tool designed to safely break thin scraps or small pieces of glass that are too difficult to hold by hand. By clamping the glass between the flat jaws and applying pressure with your thumb, you can break it precisely even in situations where running pliers are difficult to use. Place the jaws at a point outside the score line and use the line as a fulcrum to bend the glass.
Although they can be used for grozing, types without serrated blades are not suitable for scraping. Glass pliers come in two types: those with smooth jaws and those with serrated jaws designed for grozing. It’s important to choose the right type for the job. When purchasing, check the jaw width and how the grip feels in your hand, and select a pair that fits your hand size.
