Believe me, once I got stuck with only a SwissTool.
In the evening one of the kids came with a bottle of wine and no cork screw around- We managed to somehow open that bottle before starting to climb on the walls, but since then, I sweared to never get caught without my Wenger in my pocket.

There was one Leatherman with a cork screw, but is discontinued now.

No worries here: not a fan of Leatherman anyway
