Well, to answer this question briefly, we would say yes, you can use them, but there are some cons to using scissors. Firstly, the scissors are too big and heavy. Scissors may also cause pain in your hands and fingers if you use them for longer periods, and they lack accuracy when compared to thread nippers. Thread snips are specifically designed for sewing related work, they are small in size, lightweight, and easy to carry and control. Therefore, using them for smaller and quick tasks is much more convenient and efficient.
