A cutting straightedge is used for drawing or cutting straight lines and for checking the straightness of any line or surface. It is a functional tool for all drawing and drafting applications. Designed for accuracy and precision, these cutting straightedges come with beveled or elevated edges that allow smear-free drawing. Some cutting straightedges are equipped with ball-bearing pulleys for frictionless and smooth operation, while others offer comfortable grip bars for easy and total control. They are available in various sizes and materials to accommodate different needs and preferences.
