|Both of these pairs are rare. The gold plated must have been done for a special purpose. And the chrome one has a rivit. The rivit was only used for its first year of manufacture. After that a Philips screw was used. The shear was designed by Norman F Wiss Jr and a product developer in Florham Park, NJ. The product's introductory flyer is dated September 1952. The style remained unchanged through to 1976. In the 1950s they were shipped in a box with a folded insert. These are in a family collection.
