A good quality machinist rule is an indispensable tool used by machinists, woodworkers, architects, draftsman, scientists, students, DIYers and more. When used correctly, a good steel rule is a surprisingly accurate measuring device. These rules are made from Japanese rust-resistant stainless steel that has been tempered creating a measuring tool that can flex if needed but will snap back straight. The edges and ends have been ground parallel, straight, smooth and square.
