These are traditionally called Blindman's Rules, because the markings are very large and easy to read. They remain just as attractive and functional today as they were 100 years ago. With their complex solid brass joints, these hardwood rules are not easy tools to make well. Highly recommended as one of the most classic tools any woodworker can add to his toolbox. The 36" length folds down to a 9" long section. Easily slips into a pants pocket.
