Upper Blade for Cutting and Sewing / Overlock PFAFF (Ref. 29-924993-70/641)

The blades of an overlock machine are at the heart of a perfect finish. With intensive use, and especially when cutting thick fabrics or accidentally running over pins, the upper knife loses its cutting edge (becomes dull) or gets small dents.
This replacement upper blade restores clean, precise cutting without chewing up fabrics for your overlock machine. It is essential to replace the knives as soon as you notice that the machine is fraying the fabric instead of cutting it straight, to avoid straining the motor and damaging the needle plate.
