(I googled, but found nothing that made sense!)
Clover calls it a Thread Cutting Pendant. I bought mine at JoAnn, but Amazon sells it, and I think I saw one at WalMart. Besides Clover, I saw a Susan Bates version and a Dritz version when I looked at Amazon. They are a circular blade, like rotary cutter blade, inside a pendant with small notches to cut thread.
I take applique just about everywhere I go. I have the applique pieces turned under and ironed onto freezer paper with all the other pieces for that block. Each block is in it's own quart baggie. They all fit neatly inside a gallon bag - I made a tote just slightly larger to also hold thread, thimble, seam ripper, glasses, and wallet. Makes it easy to get what I need for wherever I am. I can add more to it if I need to and it still stows under an airplane seat. I take the tote everywhere I go that I will be sitting and waiting. And the pendant thread cutter is perfect.
