SOLID STAINLESS STEEL FRAME AND HANDLE - The Rosewood Wine Glass has a solid stainless steel base. On this base, hand-cut rosewood panels are secured to the frame by stainless steel rivets Stainless Steel Fluted Worm Gear The corkscrew features a stainless steel fluted worm gear. Made from a single piece of stainless steel, the worm gear is not only aesthetically pleasing, but also practical. The grooves in the worm gear create friction between the cork and the worm gear for greater and smoother cork pull. Stainless Steel Serrated Knife The corkscrew comes with a stainless steel serrated knife. Unlike the dull standard configuration knives found on most corkscrews, our stainless steel serrated knife cuts cleanly through the foil, allowing for an even cut and clean removal of the foil.
