Lower Knife (Thin) - Part #42046 for Singer 81, 81K, & 81U Series
Maintain a sharp, clean edge on all your sewing projects with this Lower Knife (Part #42046). Engineered specifically for the Singer 81, 81K, and 81U industrial overlock series, this "thin" profile lower blade acts as the essential stationary cutting partner to your upper knife.
If your overlocker is chewing fabric or leaving a ragged edge, replacing your worn lower knife is the most effective way to restore a smooth, professional shear.
Key Product Highlights
Precision Thin Profile: The slim design is optimized for fine-tuned trimming, allowing for clean cuts even on intricate curves and delicate fabrics.
High-Tension Steel Construction: Made from industrial-grade, heat-treated steel to ensure the blade remains rigid and sharp under high-speed operation.
Seamless Integration: A direct for part #42046, designed to fit perfectly into the lower knife holder of your Singer 81 series machine.
Friction Reduction: The polished surface minimizes resistance, preventing heat buildup and ensuring the fabric glides smoothly through the cutting zone.
