One of the most recognized brands in the world, Zippo was founded in the fall of 1932 by George G. Blaisdell in Bradford, Pennsylvania, where it has manufactured over 550 million windproof lighters. With the exception of improvements to the flint wheel and modifications in case finishes, the product remains unchanged. Zippo's diverse product line includes lighters and accessories; butane candle lighters; fragrance, and a robust line of heat and flame products for outdoor enthusiasts. Zippo markets in nearly 200 countries and also owns the Ronson brand of lighters and fuel and W.R. Case and Sons Cutlery Company, both based in Bradford, Pennsylvania.
