Titan is a simple-looking, yet highly challenging metal puzzle and take-apart puzzle by Felix Ure. DESIGNER: 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; Mr. Puzzle's video review is excellent but does contain spoilers. It is with the heaviest of hearts and deepest sadness that we must announce that Eric Fuller passed away suddenly and unexpectedly of natural causes in the early morning hours of November 5th, 2022.

Score for TITAN

Eric was a truly gifted man in so many ways, and a pillar of the puzzle community. A brilliant designer, welcoming ambassador for the art and hobby, deviously sharp wit, and genuine friend. His loss will be felt by all. He founded Cubicdissection.com with nothing but some hand saws, chisels, and ideas, and led it for 20 years, building it into one of the foremost sources for fine art puzzles, with customers and fans all around the world. We at the company intend to proudly continue carrying his vision forward, because we know with certainty that it's what he would have wanted us to do. There will be some challenges for a period of time as we sort through this tragedy, so we humbly ask for your patience and ongoing support during this difficult time; rest assured that we will not let his banner drop and we promise that we will be as transparent as possible in communicating with you what's to come. We can all take solace in having been so privileged to know him and enjoy his friendship and his creations. Every time each of us has an "ah ha!" moment in solving one of his many incredible puzzles, we get to experience our connection with him and his life's work. That joy was his gift to us, and it can never be taken away.
