My favorite is the Fons & Porter red and white seam ripper. I have bought about 5 of them, and can usually only find 3 at any given time...So many of you like the Clover seam rippers I may have to buy one of those, too. I do love Clover products, so I'm sure I'll like it. The one which came with my Babylock works well, too, but I prefer the fat handled ones.
