It's the Gingher seam ripper. I have one, and I LOVE LOVE LOVE it! Won't use anything else. You can get replacement blades which they say is not needed because the curved blade doesn't get dull. However, after taking apart countless blue jeans for quilts for my nieces and nephews, I did change the blade. So if you get a chance to buy one with an extra blade, do that. It's worth it.
One of the nicest things about this seam ripper is that the very, very sharp curved blade retracts completely into the handle, so it's safe to leave in plain sight in your sewing room.
