Premium Replacement Upper Knife (Part #131-50503C). This high-quality generic component is precision-engineered for the Juki MO-6714S Series, providing a cost-effective solution for high-volume industrial environments without compromising trimming accuracy.

Precision Fabric Trimming
The upper knife works in a rapid "scissors" motion against the lower blade to shear fabric excess perfectly before the overlock stitch is formed. The 131-50503C is designed to maintain the factory-specified cutting angle, ensuring a smooth, fray-free edge on a wide variety of materials, from light knits to medium-weight woven fabrics.
