Hoffmann Nut - Brass 6 Piece Burr Puzzle

A traditional 6-piece burr puzzle, beloved for over a century!  The plain-seeming exterior of this burr belies the mysteries within.  While one may pickup and disassemble a simple burr in seconds, the toughest burrs flummox even hard-core puzzle lovers.  This broad range of challenges has kept burr puzzles in the forefront of puzzle collections for decades.

Hoffmann Nut is part of a series of small 6 piece metal burr puzzles made by Grave Raven.  Each puzzle in the series appears identical when assembled, but each variant is made up of a different combination of pieces.  Grave Raven has designed their burr pieces to interoperate not just with the other 5 pieces in the puzzle you purchase, but with ANY piece they produce in the same series!  This means you can start your collection with a single burr puzzle, and add individual pieces or entire sets later, assured they will all fit together.

Hoffmann Nut- An early burr design described in Hoffmann's book of puzzles in 1893.  Will you be able to reassemble it?
Note: Contains pieces (001, 1024, 824, 188, 960, 256)

These burrs use "6 mm series" pieces, which means each little 'cubie' is nominally 6 mm center-to-center.  These are length-6 pieces, so their approximate total size is 0.5" (12 mm) wide and 1.5" (36 mm) long.

Other puzzles in the 6-piece burr series: Chinese Cross, Diabolical Structure, Six-Way Set, Yamato Block
Each style is available in aluminum or brass.
