Lower Knife for Overlocker / Overlock (Ref. 412749)

Maintaining the cutting system is the secret to impeccable overlock stitching, with the lower knife (fixed blade) being one of the most critical parts of the process. Its natural wear over time causes the cut to lose effectiveness, leading the machine to "chew" or fray fabrics instead of providing a professional finish.
Timely replacement restores cutting precision and avoids unnecessary strain on the machine's motor.
