What cutting method is used to create pinked edges to prevent unraveling?

The method that creates pinked edges to prevent unraveling is through the use of special pinking shears. These shears feature a serrated blade that cuts fabric in a zigzag pattern, which prevents the edges from fraying. When fabric is cut with pinking shears, the design of the blades helps to disperse stress along the cut edges, reducing the likelihood of fraying or unraveling, especially in woven fabrics. This technique is particularly beneficial in fabric projects where a clean, finished edge is required without the need for additional finishing techniques, such as hemming or binding.

Other cutting tools, like rotary cutters or utility scissors, do not provide the same zigzag edge, and standard shears simply cut straight lines, which can lead to unraveling when the fabric is subjected to tension or wear. Pinking shears are specifically designed for this purpose, making them the most suitable option for creating pinked edges that inhibit fraying.
