A seam ripper is an essential small sewing tool used for cutting and removing stitches.
A seam ripper is designed to do the job safely. One point of a seam ripper is sharp while the other has a ballpoint tip which prevents unintentional injuries and prevents ripping the fabric.The cutting edge of the ripper is the curved pit between the point and the ballpoint. With the sharp point you can go underneath the stitches. The ballpoint can slide against the fabric without damaging it.
