Genuine Juki Narrow Upper Knife (Part #131-50602). This authentic OEM component is specifically engineered for the Juki MO-6716S Series, providing the "narrow" profile required for specific seam widths and delicate 5-thread overlocking.

Precision Narrow Trimming
In high-speed industrial sewing, the width and profile of the trimming blade are critical to the final seam allowance. The 131-50602 is manufactured to Juki’s exact geometrical standards, ensuring a clean, razor-sharp shear against the lower blade while maintaining the narrow clearance necessary for specialized MO-6716S sub-classes.

Why Choose the Genuine 131-50602 Narrow Knife?
MO-6716S Specialized Profile: Designed specifically for the "narrow" trimming configurations of the 5-thread safety stitch series, ensuring immediate alignment and the correct cutting arc.

Superior Edge Retention: Crafted from Juki’s high-grade hardened tool steel, which maintains its sharp cutting edge significantly longer than generic alternatives under heavy-duty use.

Burr-Free Fabric Edges: Features a micro-polished surface and factory-honed edge to prevent fabric snagging or "chewing," even on difficult synthetic or tightly woven materials.

Reduced Mechanical Stress: A perfectly balanced, genuine blade reduces vibration and heat buildup in the knife drive mechanism at speeds up to 7,000+ RPM.
