Upper Blade for Cutting and Sewing / Overlock (Ref. 396001-14)

The blades of an overlock machine 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 dents.
This replacement upper blade (moving knife) restores clean, precise cutting without chewing the fabric 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 damaging the needle plate.
