The Hyperboloid Burr is a very fun six-piece burr puzzle made from identical hyperboloid pieces, designed by Oskar van Deventer and Naoaki Takashima.
The puzzle has two solutions. The six-piece version is a put-together that assembles and displays well, but if picked up by a single piece falls apart under its own weight. The seven-piece solution is completed with a satisfying "click" and holds together well.
Both assemblies are made possible by machining to very accurate tolerances. A mere 0.03mm variance and the seven-piece version of the puzzle either does not assemble or falls apart!
Note: This copy has been solved and is in used condition. Noticeable patina is visible. Original packaging is not included.

These puzzles are extras and oddballs that have accumulated in the shop. Sometimes when we make a run of puzzles we will have a few with different woods, etc. which are too much trouble to list individually on the website. These puzzles are all fully functional.
