I couldn't pull up the page on Nancy's Notions, but the seam ripper with the surgical blade is fantastic! It is super sharp! You barely have to touch the thread and it tears apart. Nothing like it at all. I bought a man's beard shaver for $11 and it works so well that I use it mostly, but the surgical blade is superb! There are two kinds out there, one is crappy, don't get it. It is from Gingher. Believe it or not, it is dull. It's the other one. You can get it at
