How to solve the Hanayama Cast Enigma metal puzzle

Want to impress your friends by solving a puzzle? Watch this video tutorial to learn how to solve the Hanayama Cast Enigma metal puzzle. This Cast Enigma puzzle from Hanayama provides a difficult solution, and has a 6 out of 6 difficulty rating.

Directly from Hanayama: Patented in America in 1975, the somewhat swirled pieces of this puzzle by Eldon Vaughn must be disjoined and then put back together. I once found a smaller version of this puzzle about twenty years ago in America, but considered it impossible to solve at the time. We have made a new version maintaining the difficulty of the original and licensed it for the cast Cast Puzzle series. This is without a doubt among the most difficult of all puzzles. The key word is 'Twist'. Don't use too much force...the pieces should just slide apart.
