The Incra Rules use a proprietary process to insure that all marking holes and slots are exactly dimensioned to accommodate a 0.5mm pencil. Not too big, and crucially, not too small. They also have a proprietary matt finish on all of their rules to ensure a non-glare view of measurements in all light conditions and all light angles
