Overview
As far as I know, this is Ali's first bolt puzzle design that he has produced for sale commercially. And a really nice one too!

I have played with a number of bolt puzzles in the past and for most of these, the solution involves most of the time finding a way to unlock the nut (usually held in place by a retaining pin of some sort) and screwing the latter out. 

Ali's bolt puzzle is rather different from the majority in that while the goal is still to unscrew the nut from the bolt, the solution is very unique and the first time I have come across such a dissimilar and unusual solving method. Kudos to Ali for thinking up something different from the rest.

This is one of those puzzles that I can't say more here without letting out spoilers, so my only advice for those interested is to go purchase one from Ali, and I am assuming he still has some left for sale or will be making more. For the craftsmanship and work put into it and from a puzzling aspect, its well worth the money!

Difficulty Level

Not difficult once you discover what needs to be done and how the puzzle works. But rather tricky tho'. Certainly the solution was not at all what I thought it would be or expected and the puzzle stumped me for a while.
