I have used literally hundreds of different kinds of corkscrews, and none work better than this swing-a-way. It's quicker and cleaner than the one with wings, surer than those with side tabs, and one of the best things is the wheel foil cutter--not a blade--which means I can travel with it.
Ever been in a hotel with a bottle of wine and no way to open it? I give them as gifts to my traveling friends, too. They are very appreciative!
