OK, so maybe "saved the day" is a little overboard, must be the MacGyver in me, but it did help out some kids. Here's my story.
The police/fire dispatch office I work at is also part of the local community center, and the dispatchers also oversee it. Well, they're having a youth group summer camp here for the next couple of weeks and so they bought a lot of board games and other toys for the kids to use. One of the games, Operation, required batteries, and to get to the battery compartment, you have to remove a small screw. Well, it seems they didn't know this, so nobody brought a small screwdriver with them. Well, the folks running the camp decided to come to the office to see if I had a screwdriver. After looking around the office and not finding one, I had a "knife moment". I had a small screwdriver on the little Vic Classic on my keychain! So, I quickly removed it from the rest of the keys, went into the game room and unscrewed the battery compartment, zipped open the batteries with the little blade, put them in the game and screwed it back on, and set the kids to playing. Nobody said anything negative about the knife (true, it is tiny, but still) and I even got a few compliments on how useful it was.
So let's hear how others have used a SAK to "save the day".
