I've got a Victorinox Officier in the junk drawer that I found on the side of a road. I never tried to sharpen it. I suppose if I ever need a corkscrew it will be handy. I recall from my student days where somebody would show up at a party with a bottle of wine with a cork and hilarity would ensue. My taste ran to Silver Satin. If you didn't want to drink the crap you could always pickle a pike.
