I have used a lot of seam rippers in my time from ergonomic to cheappy. The hands down best seam ripper I have ever used is one made by the other Rodney in LA and it is wonderful! Double ended with a small ripper on one end and a larger ripper on the other with a hand lathed handle from beautiful woods it is a very useful piece of art that I use daily. amazing how much unsewing I do because I change my mind about something.
