Leatherman Squirt saves the day.
A few days ago, my wife had some cavities drilled. They numbed her up, so she couldn't feel the aftermath. Turns out they did a sloppy job at the finish. The filling is not level; messed up her bite, and there was a bit of filling splash out stuck to the inside of one of her molars, which was cutting her tongue.
After a while, she kept complaining of how painful that is, and how hard it is to eat.
I offered to get my Dremel and just take it off right quick, she was OK with that, but I wasn't so sure that's a good idea.
I decided to go a slightly softer route and try to file it off. First, I tried the Victorinox Executive's file, but the serrations in the file don't start until a good distance down the tool, and it is also pointed, so I couldn't overshoot, or I'd be poking her with it.
So I switched to my little Leatherman squirt, my smallest MT, along with the Micra. The Squirt's file's serrations start immediately, and the tip of the file is square. So I had her open up and made a good go of it. I filed it almost all the way off, little by little, with the fine side. I didn't want to get ALL of it off and start filing into the enamel of her tooth, but it is enough that it doesn't bother her any more. She can have the dentist fix the rest when they grind the main part of the filling down flush.
I will keep this story in mind when/if she complains about me having too many SAKs or MTs. In this case, the SAK files were not up to the job, as they all have pointy tips. The more toolish file of a plier-based MT was just the ticket!
