You don't need to be a waiter to love this Left-Handed Folding Waiter 4-in-1 Corkscrew ($20) from Lefty's The Left Hand Store, which contains a knife, corkscrew, bottle gripper, and bottle opener. What makes it perfect for lefties? The screw rotates counter-clockwise, which is much easier for lefties to use than the traditional right-handed corkscrew.
