Clover ripper? I have to search it up when I have time. I have and old seam ripper that came with a 201, it is the best so far. The ones I bough randomly in stores or on ebay doesn't do the job at all. I am on the look for a pair of very sharp point scissors; I have a few small thread and embroidery scissors I have used for ripping seams, but I also have a pair of very old embroidery scissors, one of the silver handles have come off, but generally they are of a quality I haven't found anywhere. Very sharp tips, finely made, firm feel to them and I wish I knew who made them. The don't make small every day items as nice as this any more, I think it was a gift to someone in the 1920s. I need a new pair of small scissors, but it has to be the right quality to be worth it. I talk too much, but my main point is, you don't know you have a good seam ripper or pair of scissors or until you have tried one.
