The Innovation is the most cost-effective Coutale Sommelier corkscrew. This corkscrew is completely bombproof and built on an unbreakable stainless steel frame. Features include Coutale Sommelier’s patented automatic knife closure, a sharp micro-serrated knife, and a teflon-coated worm. Unlike other Coutale Sommelier corkscrews, the Innovation features a manual double lever.
