Puzzle, A Problem in Nails

Puzzle, A Problem in Nails

Description
This disentanglement puzzle consists of two entangled bent nails that are to be separated. They fit in a paper envelope, distributed by the American Steel & Wire Company, a subsidiary of United States Steel. A mark on the envelope reads in part: A PROBLEM IN NAILS.
The American Steel and Wire Company became a division of U.S. Steel in 1901, and remained a division until 1964.
A solution to the puzzle is given in a 1920 A.C. Gilbert publication cited below. Slocum and Botermans discuss the history of the puzzle.
