I vote for my Martelli Rotary Cutter and my fancy seam ripper that is a little razor blade on a finger nail file looking stick. It's really more of a seam slicer but it does have the little pick end on the blade that came pre-installed. It comes with extra little razor blades in different shapes. It is sharper than the normal seam rippers and I don't stab myself with it like I do with the others. I had a smaller version that I got from Shirley's Sewing Stuff which I also loved but then I found it's big brother at a Hancock Fabrics that was going out of business. I don't see it on their website now so not I'm not sure what brand it is.
