The Boomerang Corkscrew features a unique combination of waiter's corkscrew and foil cutter. Yes, we know the foil cutter is standard on a waiter's corkscrew, but it's usually a blade. The Boomerang, in addition to the standard bottle opener, boot, and worm, offers a retractable 4-wheel foil cutter, making stripping the foil off a bottle even easier.
