Titan will be back in stock in late June.
Titan is a simple-looking, yet highly challenging take-apart puzzle. The first design by Felix Ure, it's widely regarded as being both incredibly difficult and very satisfying to solve. The goal is to open the sphere but to do so you must defeat the mechanism which keeps the two spheres together.
Machined from solid brass, Titan measures 2 inches (50mm) in diameter and weighs 515g or approximately one lb. The brass is left unfinished, leaving it to slowly patinate and darken with use. Difficulty: 9/10.
Puzzle Mad wrote an excellent blog post which included this brass puzzle.
Been fiddling with this thing for 20 days now and I'm no closer to solving/understanding it than I was when it was still in the back of the UPS truck. This thing is next level! Very little feedback from this damned little ball. Very well made and satisfying to fidget with. If I ever figure it out, it's gonna be one hell of an endorphin rush.
Worthy and enjoyable….
