Solid brass ends cap an aluminum core, with bananas made from very accurate and nicely milled brass stock. The feel and heft of this puzzle speak to its...

The acrylic top is held in place with a tricky set of shoulders resulting in a tight fit while retaining ...

Solving the Half Hour cube will only get you partially there, as the "T" shaped restriction limits the assembly to one solution.Previously existing as a prototype made ...
