Color Changing Knives. Nashville: Sanders Manufacturing, 1950s. Set of seven knives for the popular close-up routine, six with stag/colored handles, one with a green/grey and red composition. Colors include peach, solid green, green flecked, green/grey, shiny green, and one black/black knife. Each blade hallmarked. An unusual and possibly unique set. The standard Sanders-made knife sets were made up of a white/white, white/black, and black/black knife. In this set, the solid green/black knife was painted later, but the other unusual handles are originals and factory-made.
