Billet Knife or Lemon Knife. Hamburg: Willmann, 1930s. Spring-loaded mechanism concealed in a seemingly ordinary butter knife injects a small coin into a lemon as the fruit is cut open by the magician. Purchased by Charles Larson from the Willmann factory in Germany. Requires a shim to load. With instructions and notes in Larson's hand. Length 10". Minor splitting to blade. A precision-made prop and an unusual example of this clever apparatus.
