The 130 teeth zigzag blade is made of tool steel (SKD-11) imported from Europe, processed by well heat treatment to increase its mechanical properties such as toughness and wear resistance. The blade tip is precisely ground to maintain an equal tooth pitch and peak, the slitting edge will generate the zigzag notch, to facilitate tearing along the notch. The zigzag blade is suitable for easy-tear applications such as medical tapes.
