After sewing for many years and hating to use a seam ripper, especially the ones that came with my machines, I went shopping for one with a larger ergonomic handle and found the white Clover and fell in "love" with it, now "Jack the ripper". Then bought and F & P red and white one with a larger handle but found that I prefer the Clover as it is easier to get in between the fabrics when ripping a long seam, but does an excellent job. I believe mine were NEVER sharp, so made ripping very difficult. Now "Jack the Ripper" and I have become VERY friendly and work well together.
