are there any other uses for a corkscrew besides opening a bottle of wine?

since i carry my swiss army knife wherever i go and i have used it to open a bottle of wine several times when my regular corkscrew went MIA (or didnt join us on the picnic), i was wondering if those guys over at victorinox assume that most of their customers drink enough wine to include a corkscrew on most models of their knives.

is there another purpose for such a tool?
