A Zig-Zag Blade is a type of cutting blade with a jagged, saw-toothed edge that is designed to cut materials back and forth. This blade is found in a wide range of cutting tools, including utility knives, fabric scissors, and rotary cutters. It comes in a variety of shapes and sizes, with varying serration patterns to suit various materials and applications. Zig-Zag Blade is also designed to stay sharper for longer periods of time than a straight-edged blade, making it a long-lasting and durable cutting tool. It is commonly used in craft and DIY projects to cut through materials such as fabric, paper, cardboard, and foam.
