A thimble and flexible folding measure is must for every craftsman. It's traditionally manufactured from downy birch. Metric scale in black on both sides, and red decimetre figures. Coated with a water-based protective lacquer for increased resistance to dirt and moisture. The joints are heat-treated, epoxy coated, made from Swedish steel and oiled at three points to ensure first-class performance. Each folding rule section is checked twice during the production process with high-speed cameras. Type approved as per EU Class III.
