@kimbladewiper: Triangular blades spread pressure → weak wiping. As the tip collapses, the chatter starts. Square blades focus pressure on the edge → stronger, cleaner wipes. The 4-joint link keeps the tip in shape, so they last longer and stay quiet. The answer? Square. 🔗 https://kimblade.com #Kimblade #Wipers #WiperBlades #CarCare #RectangularWiper
