The Rabbit Zippity 2-Step is the first and only waiter’s corkscrew with a retractable foil cutter. After using the foil cutter to remove a foil cap, it retracts automatically when the levers are opened. And the Teflon-coated spiral turns into the cork up to 5 seconds faster than an ordinary spiral. The time saved—10 seconds or more on each cork pull—is important to a waiter who may open dozens of corks on a busy evening. Lifetime Warranty.
