Take the two disks apart, that is the objective of this beautifully metal cast puzzle.
A word from the designer:
"The World Puzzle Designers' Forum, held in August 2000 in Los Angeles was where I first met my close friend Oskar. This puzzle is based on a disc puzzle that he showed me at that time. Battling it out with this puzzle is like putting your mind to the test against one of the world's sharpest minds. The idea to keep in mind here is 'circle'."
