The evolution of corkscrew design is clearly presented in extensive text and displayed in over 500 photographs - over 450 in beautiful color - and 1000 U.S. patent drawings dating from 1851 to 1994. Brother Timothy Diener, the former winemaker at the Christian Brothers celler in Napa, California has written the Foreword.The book is arranged chronologically to show the development of designs. Here is a progression of corkscrews from common to unique, in materials from metals to plastics, and in value from inexpensive to priceless. The diversity is amazing. This book is a unique blend of primary research, visual excitement, and friendly dialogue which enriches our appreciation of corkscrews.
