I would have to say my manicure scissors have been my favorite tool lately... I use them as a seam ripper, to trim threads close on embroidery machine projects, little clips in a seam line, those little curved blades come in very handy off and on throughout the day... they are small enough to sit by my machine and not get in the way. I have an older pair that I use for paper, they are awesome when cutting out curves smoothly for templates, or into a V.
When I heard the clapper...I thought of that gadget that when you clap your hands a light turns off... :? Had me stumped til I checked the link... I had not seen one of those before! I will have to check it out!
