Cast Keyhole

I gave this as a gift to my son-in-law. Last time we were talking about Hanayama puzzles, he said that this is his favorite, because even though you know how it works, it still takes some really concentration to get the pieces apart, and then back together. I like this one because no mater how many time you do it, it doesn't really get any easier, because of the sequential steps it requires; if you lose track of where you are, you may have to backtrack almost to the beginning again

Took longer than expected to take this apart, and even longer to put back! Difficultly rating is appropriate, don’t be mislead by its appearance as a simple puzzle - it’s trickier than you think but lots of fun! Great quality as usual as a Hanayama puzzle. The polished metal and weight of the material makes it a very satisfying puzzle.

Held off on buying this for awhile because it looked too easy.. Finally purchased it and I was very glad I did! Awesome little puzzle where you think you're making progress only to find you need to circle back to the begining. I would recommend to puzzle lovers of any skill level. Really a fun little piece to solve, and reassemble.

The solution is very interesting. But like many other maze-like puzzles, the design (in terms of looks) is not appealing to me. However, I'd recommend it to everyone - beginner or pro in such puzzles.

This is a great little puzzle. Very sturdy and a good weight. The "maze" is much longer than it first appears and takes an open mind to solve it. The real challenge is, once it is apart, shuffle to two pieces and walk away for awhile. It will be harder to put back together than you think.

Fun to fiddle with, maybe over rated in difficulty a bit. Has a nice size, weight and sturdiness, looks good. The solution is a little longer and more complex than you might guess from a first glance, but only requires some perseverance to find it.
