Upper Knife for Cut and Sew / Overlock PFAFF (Ref. 29-924993-56/000)

The blades of a serger are the heart of a perfect finish. With intensive use, and especially when cutting thick fabrics or sewing over pins, the upper knife loses its cutting edge (becomes dull) or gets small nicks.
This replacement movable upper blade restores a clean and precise cut to your classic overlock machine. It is essential to replace the knives as soon as you notice that the machine is fraying the fabric, to avoid straining the motor and to ensure a professional finish on your seams.
