The top edge dry measure is made of which material?

A top edge dry measure needs a material that stays true to size and maintains a precise edge through repeated use and exposure to humidity and temperature changes. Metal provides the best combination of rigidity, wear resistance, and dimensional stability, so the edge remains straight and square over time. It resists swelling, warping, and deformation that wood or cardboard would experience when exposed to moisture. Plastics can creep or wear differently and may not hold a precise edge as well as metal. For these reasons, metal is the best choice to keep the instrument accurate.
