An industrial overlocker, also known as a serger, is a specialized sewing machine that utilizes multiple threads to stitch and finish edges of fabric simultaneously. It is designed to prevent fraying, enhance durability, and provide a professional finish that is often unattainable with standard sewing machines. Overlockers can handle a variety of fabrics, making them a versatile choice for both small and large-scale production.

The benefits of using a threader extend beyond convenience. For individuals with vision impairments or those who find it difficult to manipulate small objects, a threader can be a game changer. By taking the stress out of this initial step, sewists can focus their energy on what truly matters the art of sewing. Moreover, threaders come in various types, including manual, electrical, and those designed specifically for different needle sizes, catering to a wide range of users and preferences.
