Upper Knife (Thin) - Part #42111 for Singer 81, 81K, & 81U Series
Keep your edges clean and professional with this Upper Knife (Part #42111). Specifically engineered for the Singer 81, 81K, and 81U industrial overlock machines, this "thin" profile knife is designed for precision trimming on a wide variety of fabrics.
A sharp, high-quality blade is essential for preventing frayed edges and ensuring your overlock stitches lay perfectly flat. If your machine is pulling fabric or leaving uneven cuts, it is time for a fresh replacement.
Key Product Highlights
Precision Cutting: The "thin" design allows for sharp, accurate trimming, making it ideal for navigating curves and fine edge work.
Hardened Steel Build: Manufactured from high-carbon industrial steel to maintain its razor-sharp edge through long production runs.
Direct Fitment: A for part #42111, ensuring seamless compatibility with Singer 81 series overlockers.
Smooth Performance: Friction-resistant coating reduces heat buildup, preventing the blade from "gumming up" when cutting synthetic materials.
