Mustache trimmer to use as a seam ripper. Its amazing how quickly you can un-sew a long seam using this. I first saw this at a retreat. I could hear this buzzing every once in a while from across the room. Finally had to go investigate. On the way home, stopped at the store and bought one. When I got home, told hubby hey I bought you a present! He looked at it and said "why do I want that, I don't have a mustache" To that I said oh, I forgot, guess I will have to use it to rip my seams. grin. I didn't think he would ever stop laughing.
