Thread cutter. Manual thread cutter designed for industrial lockstitch sewing machines. The device consists of a spring that tightens and holds the thread, and a sharp blade that allows for quick and precise cutting in a single motion. After cutting, the thread remains held in place, ensuring a clean and straight initial stitch for the next seam. The cutter is easily mounted on the presser foot bar — together with the foot — and fits all lockstitch machines where the foot is attached with a single screw. It’s a quick and smart way to upgrade your sewing machine’s functionality without altering its structure.
