Can you remove the ring from the puzzle without cutting the rope?

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!
