The Monkeys' Nuts! Puzzle Bolt

This is an impossible object: the puzzle is to decipher how it was made!

The Monkeys Nuts is Two Brass Monkeys' take on Scott Eliott's "Its Nuts" design. Originally only available in 3D print by Scott, our version is a beautifully crafted solid brass bolt with two nuts threaded on it. But all is not as it seems! A fine piece of mechanical engineering makes this bolt very, very special.

To remove one nut turn it clockwise. To remove the other, turn it counterclockwise. If you hold the two nuts and rotate the bolt they each move in different directions...this is seemingly impossible, as the bolt has the same thread along its length.

Milled from solid stock and measuring nearly 3" x 1", the entire assembly weighs a whopping 16 ounces. This object is large and very well made.

Handling Metal Puzzles
While all metals tarnish over time, residual oil and salt from handling speeds up the process and leaves fingerprints. An individually packaged metal cleansing cloth is included with each metal puzzle sold on Cubicdissection. Metal Puzzle Polishing Kits which contain a larger cleansing cloth and microfiber polishing towel are also available.
