After 10 years and many, many hours spent on this puzzle, I'm slowly seeing it worn out more and more. I'm completely stuck and whenever I pick this up again I end up doing the same that I've already tried before.
First, has anyone ever solved this? I've had my doubts once in a while, but since it can be bought on This swedish puzzle-site it should be solvable. It is called "very difficult" on this page.
Can anyone help me to solve this puzzle?
EDIT: The ring can pass the black loop. The white loop on the wooden handle that holds the black loop can pass the big heart tightly. The ring can pass the loop sitting on the big heart. The ring fits on either side of the wooden handle.
