Cast Equa - Hanayama Metal Puzzle

This was my gateway puzzle. The very first cast I'd ever purchased and it launched my fascination with puzzle collecting over a year ago. It's one of the most difficult casts I own and reminds me every time I think I can resolve it at will. Took me over 3 weeks to completely solve and still gives me trouble whenever I pick it back up. I absolutely love it's design and really think it's everything that a great cast puzzle should be. If you're a fan at all of cast puzzles, this one is a must have. And yes, it's really flippin difficult!
