Based on the science of topology which is the study of forms and surfaces, this puzzle is called Wit’s End in the New Book of Puzzles (J.Slocum & J.Botermans). An easier version called Sword Puzzle was patented in USA by Robert Boomhower in 1968 but of course, here at Mr Puzzle we had to make the difficult one!
