I find this interesting as I have seen others ridiculed for including a paper clip in their mini kits. Obviously the ones doing the ridiculing didn't think it through and I am afraid the ones who were being ridiculed took the advice to heart and eliminated this obviously useful implement from their kit. The only disadvantage is some of the mods require other tools you may not have on your person. Still, if you might need a short length of wire for something it seems worth throwing one or two into your kit.

Also you can use one to unclog a glue applicator tip.

I can't think of anything else original to add that hasn't already been mentioned so ... yeah ... what everybody else said.
