I bought the razor sharp curved blade ripper over a year ago and LOVE IT!!! There are two kinds. It doesn't have the name on it, but the other one isn't sharp AT ALL!!! I use the curved blade and use it every 3 stitches and then use the new seam ripper that is like an eraser and roll it over the thread pieces and pick up every piece of thread. The lint roller doesn't seem to work nearly as well as the eraser seam ripper. Well worth the money for it. It was very inexpensive. I don't use the seam ripper part, just the eraser part. I guess you can use an eraser instead of this new fangled seam ripper eraser, but it's probably not as fast.
