The early 1950s was the era of the copper kitchen appliance. Many companies put out "Deluxe" Industrial Design models in copper or copper-plated versions, which were generally more expensive than their standard lines.
This Oster model 522 double action electric knife and scissor sharpener is a good example. You can use it as a wall mount or countertop appliance. It has a sliding copper plated cover, which when uncovered exposes two sharpening slots for knives and scissors. The base is a shiny black phenolic plastic.. It's about 8 by 4 by 4 inches. The cord is in good shape and it works.
There are three or four small dark tarnish spots to the sliding copper cover and there are two blade scratches to the plastic case alongside the right sharpening slot. The sharpener comes in its original box. Two different brochures featuring Oster products are included. A terrific look for your retro appliance collection or copper kitchen.
