A "pinking" shear is specifically designed with a serrated blade that cuts fabric in a zigzag pattern. This type of edge is particularly useful because it helps to minimize fraying, which can be a common issue in woven fabrics. When the edges of the fabric are left raw, they can unravel over time, leading to a less durable and aesthetically pleasing finish. By using pinking shears, the fabric edges are cut in such a way that reduces the likelihood of fraying, effectively contributing to a cleaner and more finished look. This makes pinking shears a valuable tool in fabric covering processes, ensuring longevity and maintainability of fabric edges in various applications.
