The Keencut Safety Straight Edge is more than just a ruler; it's an essential, durable safety tool designed for years of reliable service. It's crafted from high-grade materials and showcases Keencut's superb engineering principles. A key distinguishing feature is its high-grade embedded steel edge. This integral steel edge plays a vital role in preventing wear, not only to the straight edge itself but also to your cutting tools, ensuring consistent, clean cuts over time. Available in nine convenient sizes, ranging from 45cm (18”) to 180cm (72”), you can choose between imperial (inch) or metric (cm) scales to suit your precise requirements. If you need a cutting solution longer than 180cm (72″) that offers greater rigidity, consider the Keencut Simplex cutter bar.
