Upper Knife for Cutting and Sewing / Coverlock (Ref. 416364601)

The movable upper blade is primarily responsible for cutting excess fabric as the seam progresses, ensuring professional finishes without fraying. Like any pair of scissors, continuous friction eventually wears down the cutting edge, causing the machine to start snagging materials.
Timely replacement of the worn knife ensures the original stitch quality, prevents damage to fabrics, and reduces the strain on your equipment's motor.
