A longtime collector of corkscrews, author Donald A. Bull first displayed the breadth of his collection in The Ultimate Corkscrew Book, an extensive volume spanning the diversity and creativity of corkscrew production over the last several hundred years. Now with the companion guide, Bull's Pocket Guide to Corkscrews, collectors and dealers are once again invited to explore remarkable examples of corkscrews. From figurals and eclectic corkscrews to corkscrew knives, rare and novelty varieties are well represented. For easy reference, all corkscrews are classified categorically along with their current market values.
Don Bull is a retired executive with an unquenchable thirst for corkscrews and corkscrew knowledge. In 1979, he founded "Just for Openers" and is a member of many corkscrew-related organizations. In addition to two books on openers, Don authored The Ultimate Corkscrew Book.
