Just a little history lesson, the Zippo lighter was more or less invented here in Bradford by George G. Blaisdell after he used a lighter belonging to another man. That lighter was in two pieces but essentially like the zippo without a hinged top. George thought a top connected to the lighter with a hinge would be a better design, it obviously was/is. Otherwise the design is much the same as that two piece one. At one time there was a problem with the flint wheel (the little rough edged wheel that scratches the flint and makes a spark) so George stopped producing the lighter and kept his employees working with full pay until the problem was corrected. The story says it cost him quite a bit of money to do it, but he wanted a good quality product. Tere is a lifetime guarantee on a Zippo. The company has even replaced one that was run over by a paving roller, another damaged by a rotary lawn mower and many others. The factory has always been here. There was a factory in Canada, but it was closed several years ago. BTW Zippo produced the 400,000,000th lighter a couple years ago, it is on dislay at the Zippo/Case Visitor's Center, in case anyone would want to photograph the lighter. ;-)
