Technically, you can sometimes cut individual threads with small scissors.
But a seam ripper gives you much more control.
It’s narrow enough to get between stitches and layers of fabric, making it easier to remove unwanted stitching while reducing the chance of accidentally cutting the fabric
itself.
That’s especially important when you’re working with delicate, expensive, tightly woven, or difficult-to-replace material.
Scissors are designed to cut.
A seam ripper is designed to remove stitches.

How Does a Seam Ripper Work?
The basic idea is wonderfully simple.
You use the pointed end to get underneath a stitch.
Then you position the thread against the sharp inner edge.
A gentle movement cuts the thread.
