The tool on the cover of eBay Hacks is a corkscrew. The exact time origin of the corkscrew is not really known, but corkscrews descended from bulletscrews (also called gun worms)?a tool used for cleaning jammed bullets or unspent powder out of musket barrels, which shared a similar spiral tip. By the 17th century, the corkscrew was fairly common, as cork stoppers were now well-established throughout Europe, not only for wine, but for beer, medicine, and cosmetics.

Corkscrews come in a variety of styles, including direct-pull (the simplest), assisted-pull, single-lever, double- (or wing-) lever, and torsional. The corkscrew pictured on the cover is most likely an assisted-pull corkscrew; the most common ones in use today are single- or double-lever.
