Okay, so have I another seam ripper that came with my sewing machine, but after taking up quilting, this larger seam ripper has come in very handy. A good size that fits comfortably in the tool section of the plastic box, but is comfortable to hold. It cuts threads cleanly without snagging fabric (if I'm careful). Unfortunately, this seam ripper and I have spent a lot of time together correcting mistakes. ;-)
