I have been enjoying the use of my Zwilling corkscrew now for several months. It's precision and quality make its use one of life's small pleasures. It has nice weight and balance. The hinges all work smoothly. The foil cutter blade works well and the double hinged puller mechanism ensures that it works well with all types of bottles and corks. I have only one small suggestion for improvement: the coating on the corkscrew itself is intended to allow it to penetrate easily into corks. However, in my experience smoother penetration is achieved with simple, uncoated corkscrews.
