Bill's Ball Bearing Burr (Aluminum)

Product is available.
$45.00
DESIGNER: Bill Cutler
MATERIAL: Aluminum and stainless steel
SIZE: 1.9" x 1.9" x 1.9"

As longtime fans of Bill Cutler's many engaging and unique interlocking burr puzzles, we are excited to release his Ball Bearing Burr design in metal. The normal six-piece assembly is complicated by the addition of two stainless steel ball bearings which must be placed in the correct location before assembly. Once the puzzle is assembled, the bearings can move about within the internal space, requiring you to maneuver them back into the right location in order to unlock the pieces and begin disassembly. This unique concept makes it stand apart from other, more typical six-piece burrs, and if you're a fan of the archetype then this is one you will definitely want to have in your collection.

Made of machined aluminum with a sand-blasted finish, this edition has a pleasant feel in the hands, and its petite size belies the mechanical trickery within. While this version is not quite as precisely fit as our original wood version, due to allowances that had to be made for the ball bearings in conjunction with the metal manufacturing process, it does not affect the functionality in any way, and it's still just as much of a joy to solve. The puzzle ships in an assembled configuration.

Handling Metal Puzzles
All metals tarnish over time. Residual oil and salt from handling speed up the process and may leave undesirable fingerprints. Occasional use of our Metal Puzzle Polishing Kit with a coat of Renaissance Wax will keep your metal puzzles in tip-top shape! The brass pins can be removed and shined with any standard brass polish, but we do not recommend you use polish on the plates as it may damage the finish.
