The Rabbit Zippity 2-Step is the first and only waiters' corkscrew with a retractable foil cutter. When the levers are opened, the foil cutter retracts automatically, saving 5 seconds on every cork pull. The non-stick coated spiral turns into the cork 3 to 5 seconds faster than an ordinary spiral. The Rabbit Zippity 2-Step is a patented design that is the fastest 2-Step ever made. Lifetime warranty.
