Brass Monkey Five. Just a single hole and a ring at the end of each piece differentiate it from Brass Monkey One, Two, Three, and Four. It looks very similar to the other puzzles but has a completely different trick that locks its secrets.
Like the previous puzzles, it weighs almost 800g (1.1 lbs). Each piece is 70mm long and has a diameter of 19mm. This is a puzzler's puzzle. Perfect for fooling those who think they have seen it before. It looks like a standard interlocking Burr. It isn't. It makes a perfect quintet with its predecessors.
