from cubicdissection.com:I'm always excited when Tom contacts me with a new design, and this one turned out to be no exception. The "Noose" in the name refers to the fact that all six pieces are contained by a 4x4 square which constricts them like a noose. A squat rectangle with a unique level 9 solution, it is very solid until you figure out the deceptive first move. After that things get interesting, with lots of movement but only one specific disassembly. Once apart, getting it all bac...

This copy of the Pentagon box is one of the better B&M puzzles made. It's 5 years old and while it's tightened up a bit, it still works fine.

However, keeping all these symmetries and creating a new shape resulted in...

Brian also added a locking mechanism that will ensure the puzzle is more difficult to disasse...
