I took the photo on my phone, so the focus isn't great, but see that clever gizmo she's holding? It's the sharpest, neatest little stitch ripper I ever saw. The point is fine, the blade is sharp and it folds back into the handle for safe and convenient storage. When I saw it again the other night I made a decision on the spot. I must have one of those! I made a special trip to my local Quilt Store yesterday. There they were on the counter. The colours weren't so neat as the one my student has, but who cares? I bought two: one for my sewing machine and one for my teaching kit. I'm happy to report that I didn't buy any extraneous fabric. Next time I make a mistake I hope to be able to say "I'll unpick it" in a bright and breezy tone of voice just like my student does.
