A few years ago, I tried to solve the angel-like metal puzzle but in vain. Even after I had read the solution which appeared in a book, I could not solve it. For 3 to 4 years, I thought this metal ring puzzle could not be solved. Finally, about 3 months ago, I learned the solution from a friend. Level 1 is the simple form of this metal ring puzzle. The "taller" one is the level 2, which is like an angle by appearance. I tried to combine two of the level-one items together in order to tell this is the original face behind the harder one.
