Juki Lower Knife Blade A4145335000 — Genuine Replacement for MO-600 Series Overlockers
Keep your Juki MO-600 series overlocker cutting cleanly with this Lower Knife Blade (Part No. A4145335000). The lower knife works in tandem with the upper knife to trim fabric edges during overlocking — when it wears out, you’ll notice frayed seams, uneven fabric feeding, or the machine struggling to cut through fabric cleanly. Replacing it restores sharp, consistent trimming on every stitch.
Ideal for home sewers, dressmakers, tailors, and small garment workshops running Juki MO-600 series serger/overlock machines.
