In 199x...200x the Wenger company produced their Sterling Silver Series of Swiss Army Knives, consisting of seven Esquire models.
All models featured elegantly styled, solid, sterling silver (.925) scales, designed by one of the world's finest silversmiths. The Tuxedo model also featured black enameled scales.
They were sold in presentation boxes.
Branded versions, for example the Dolan Bullock model (see photo right), were also produced.
