The Upper Blade for selected 4-thread Baby Lock Models is an genuine replacement part designed by Baby Lock. This vital component works alongside the lower blade in your overlocker to deliver precise, clean cuts along fabric edges. Over time, blades can dull or become damaged, resulting in frayed edges and uneven seams. Replacing the upper blade is essential for maintaining peak performance and achieving professional-quality results.
