What are "pinking shears"?

Pinking shears are a type of scissor used in sewing to prevent fabric edges from fraying. The blades of pinking shears have a serrated edge that creates a zigzag pattern along the cut edge, which helps to seal the fabric. They are a useful tool for finishing seams on lightweight and medium-weight fabrics, as well as for creating decorative edges on the fabric. Pinking shears come in different blade sizes and are available in both handheld and electric models. When using pinking shears, it is important to ensure that the blades are sharp to avoid damaging the fabric.
