This ubiquitous feke, originally made of metal, was invented by Prof. Herwin (William Humpage) c. 1885-6; see The Magic Wand, Vol. 23 No. 164, Dec. 1934, p. 149. Later variations have been manufactured in rubber and various plastics. The feke was little noticed by conjurers until it was popularized in the early twentieth century by a New York magician, Al Meiners, who used it in his marketed method for replicating Ching Ling Foo's Torn and Restored Paper Strip effect; see Max Maven in Gibecière, Vol. 9 No. 2, Summer 2014, p. 98.
