[CHAT] My favorite tool, what's yours?

This cheap little tool is a bit of magic! Snag Nab It, so helpful. It fixes snags, helps separate thread that isn't laying nicely or is twisted, and assists greatly with clean up frogging, especially if it's just a little spot and I'm trying not to disturb the rest of the stitching.

It's next to me with my needles at all times, it's my #1 favorite cross stitch tool. What are some must have, can't or don't want to stitch withouts?
