it won't suffer from solder drops or brief touches with the iron, and has more friction than many other sprung solutions so is less likely to ping at the wrong moment. You can always rest a book on the handle end to add more weight. If you're equipping a classroom, they cost next to nothing.

I used to keep a couple with my portable iron in a travelling toolkit; the soldering parts of that were mainly for cables/connectors.
