Truly fine rulers can cost a premium, but this one is an exception. Built of thick stainless steel, its sturdiness is something you have to feel to appreciate. The graduations are etched into the metal so they won't wear away, and it's graduated in both inches and millimeters. At 18'' long, it's a great bench rule for drafting, laying out joints, and precise measurements. Convenient hang hole keeps it at the ready.
