The Upper Blade for Older 4-Thread Baby Lock Models is a genuine Baby Lock replacement part. This essential component of your overlocker works in tandem with the lower blade to create precise, clean cuts along the edge of your fabric. Over time, blades can become dull or damaged, leading to frayed edges and uneven seams. Replacing the upper blade is crucial for maintaining optimal performance and achieving professional-quality results.
