Upper Knife for Cut and Sew / Overlock (Ref. 98-784045-02/000)

The blades of a serger are the heart of a perfect finish. With intensive use, and especially when cutting thick fabrics or accidentally sewing over pins, the upper knife loses its sharpness (becomes dull) or develops small dents.
This replacement upper blade (moving knife) restores clean, precise cutting without snagging fabrics to your overlock machine. It is essential to replace the knives as soon as you notice the machine is fraying the fabric, to avoid straining the motor and damaging the needle plate.
