I haven't used seam rippers in decades, not that I don't "rip" but use these snips from:
https://www.mygoodscissors.com/ThreadNippers.htm(Item #6204 4.75 tweezer snips with curved blades). The company has very good customer service, prices and shipping. I usually order 10 at a time, and that way I have a supply on hand, if one of my quilting friends would like to buy a pair at my cost.
