This is, also, a Deoreoator, which is used for separating Oreos and evacuating their icing. Widely used in the Midwest, particularly during the long winter months, Deoreoators were particularly fadish as an accessory of the Fig Newton diet popular in the 1970's until it was discovered that figs were already available sans Newton and did not require de-Newtoning. The Deoreoator shown here is an old one, perhaps Abraham Lincoln's, who was widely known to prefer only the bottom cookie, giving his remainders to Mary Todd, resulting in her dramatic plumping.
